1.1 LIGHTING AND NAVIGATIONAL AIDS
Introduction
An inspection of the airfield lighting and navigational aid (NavAid) equipment on Merrill Field
Airport was performed on October 4, 2007. The inspection of airport lighting components
included evaluation of the existing condition of the airport lighting vault, standby generator, and
runway and taxiway edge lighting for Runway 16/34, Runway 7/25, parallel Taxiways A, B, C,
and N, and interlink taxiways. Portions of the Taxiway G and Taxiway Q edge lighting were
inspected separately as a part of the Block 5 Apron, Phase 3 rehabilitation project in 2008. The
NavAid inspection included the airport beacon, lighted windcones, runway end identifier lights
(REIL’s), visual approach slope indicators (VASI’s), and pulse light approach slope indicators
(PLASI’s). The equipment was also checked for compliance with applicable FAA advisory
circulars and local, state, and federal code requirements. Maintenance records, technical
manuals, and spare parts inventories were not verified during this inspection.
The corrective action items listed in the 2007 Annual Inspection Report included: 1) removing
and replacing the standby generator with a new enclosure outside the airport lighting vault; 2)
rearranging the regulator layout and hydronic heat piping in the airport lighting vault to meet
code; 3) fixing broken or missing lights and junction boxes; 4) replacing Runway 16/34 edge
lights south of Taxiway Q intersection; 5) upgrading edge lighting to LED fixtures; 6) improving
grounding and bonding of beacon tower; 7) replacing all lighted windcones with frangible tilt
down fixtures; and 8) replacing the existing PLASI with a new VASI approach aid system.
Since October 4, 2007, nine (9) Airport Improvement Program (AIP) projects have been
performed at Merrill Field Airport. Components of these projects have updated portions of the
lighting and NavAid systems at Merrill Field Airport. Table 1.1a identifies a list of recent airport
improvement projects that included upgrades to the airfield lighting and NavAid systems at
Merrill Field.

The airport lighting vault is located in a concrete block room on the east end of the airport
manager’s office building. The vault contains power distribution panels for the airport
manager’s office, the standby power generator, and seven constant current regulators for the
runway and taxiway edge light circuits. The 2007 inspection evaluated the vault for
conformance with AC 150/5340-30A and the Municipal Electrical Code. Multiple code violations
were identified during the inspection and are noted in the updated Electrical Inspection
Checklist included in this section. Most violations were caused by the cramped nature of the
vault and inadequate clear spaces in front of and around equipment. Recent construction in the
vault has consisted of replacement of existing electrical components with new equipment. New
installations have been installed in conformance with AC 150/5340-30A and the Municipal
Electrical Code. Existing deficiencies identified in the 2007 Annual Airport Inspection Report
have not been corrected by recent construction.
The runway and taxiway edge lights consist of mid-intensity fixtures elevated 24 inches above
grade. The fixtures are equipped with varying lens attachment methods including twist lock,
clamp band, and pop top style attachments. The lighting was checked for conformance with
AC 150/5340-30A for color, siting criteria, and installation. The general condition and operation
of the edge lighting were also evaluated. Non-conforming elements of the airport lighting
system are noted in the Updated Electrical Inspection Checklist included in this section. Airport
lighting components that have been updated since October 4, 2007 include the airport lighting
and control system (ALCS); installation of new LED runway and taxiway edge lighting for
Runway 16/34, Taxiways G and Q, and interlink Taxiways M, N, Q, R, and S; and installation of
new reflective taxiway edge markers on the north end of Taxiway B adjacent to Orca Hangars.
The 2007 inspection work also included evaluation of the rotating beacon and lighted windcone
navigational aids. The rotating beacon and windcones were inspected for conformance with AC
Page 2 of 4

2012 Updated Airfield Inspection Report
Lighting and Navigational Aids
150/5340-30A and general operational performance. The rotating beacon is located adjacent
to the south wall of the Merrill Field maintenance building, near the intersection of Taxiway Q
and Merrill Field Drive. A general inspection of the beacon was performed from ground level.
In 2011, Merrill Field maintenance noted that the beacon was not rotating consistently. Beacon
upgrade work performed in 2012 consisted of replacing the bearings, re-building the gear box,
and installing new bulbs. Beacon malfunctions have not been reported since the upgrades.
The primary windcone is located to the southeast of the intersection of Runway 7/25 and
Runway 16/34, with 4 secondary windcones located at the east end of Runway 7/25, south end
of Runway 16/34, east end of runway 5/23, and east end of Taxiway Q near the helipad. The
primary lighted windcone and secondary lighted windcone at south end of Runway 16/34 were
replaced in 2010 with new LED L-807 lighted windcones. Merrill Field opted to install 12-foot,
non-frangible, windcones at both locations for improved visibility and functionality.
The 2007 NavAid inspection also included evaluation of the REIL’s and approach aids at each
runway end. Each end of Runway 7/25 is equipped with VASI’s and omni-directional REIL’s.
Runway 34 was equipped with a PLASI and uni-directional REIL’s that face approaching
aircraft. Runway 16 is equipped with a VASI and uni-directional REIL’s. The FAA owns and
maintains the VASI and REIL navigational aids on both the runways at the airfield. Merrill Field
Airport owned and maintained the PLASI system. The inspection verified that all NavAids were
operational and noted the general condition of the equipment. Equipment aiming and signal
intensity were not measured during the inspection. The PLASI on Runway 34 was replaced
with a new precision approach path indicator (PAPI) during the 2010 Rehabilitate Runway 16/34
project. The new PAPI is owned and maintained by Merrill Field. The 2010 project did not
include improvements to the existing VASI and REIL systems owned and maintained by the
FAA. New runway lighting conductors which supply power to the REIL’s were installed in the
2010 project. FAA technicians serviced the REIL’s on Runway 16/34 after the lighting
conductors were installed but deficiencies identified in the 2007 Annual Airport Inspection were
not addressed.

2012 Updated Airfield Inspection Report
Airfield Pavement
1.2 AIRFIELD PAVEMENT
Introduction
Merrill Field manages approximately 2.5 million square feet of runway, taxiway, and apron
asphalt concrete pavement. Paved surfaces north and west of, and including Runways 7/25
and 16/34, are generally founded on relatively clean gravel soils. Pavements south and east of
Runways 7/25 and 16/34 are generally founded on poorer soils and landfill garbage. The ages
and condition of pavements are found in the attached 2009 Pavement Condition Report (James
Horn, Alaska DOT&PF). The Alaska DOT&PF performs the pavement survey and testing
approximately every 3-4 years. A new pavement condition survey is anticipated to take place
during summer 2012.
Since October 4, 2007, nine (9) Airport Improvement Program (AIP) projects have been
completed at Merrill Field Airport. Components of these projects have rehabilitated existing
paved areas at Merrill Field Airport. Recent airport improvement projects that included
upgrades to the pavement systems at Merrill Field are listed in Table 1.2a below.

Runways. Runway 7/25 pavement was rehabilitated in 2005. An approximate 75-foot by 15foot area of pavement along the south edge of Runway 7/25, between Taxiways C and D,
contains multiple 1-inch diameter divots. These divots were formed from separation of the hot
mix asphalt mixture during paving operations due to poor quality batch mixture or low
temperature application. Repair of the area should be made within the next 24 months. Coating
this area with a pavement sealer is recommended to fill in the existing divots and prevent future
pavement degradation and water intrusion. Other Runway 7/25 pavement is in good condition
and no signs of pavement heave or rutting were found.

Municipality of Anchorage
Merrill Field Airport
2012 Updated Airfield Inspection Report
Airfield Pavement
Runway 16/34 pavement was rehabilitated in 2010. Existing pavement was milled and used as
surfacing on the runway shoulders. New leveling course and pavement were installed and
compacted to 100% maximum density and 94% maximum density, respectively, as specified. A
508-foot long by 28-foot wide area located along the western edge of the runway pavement,
between the newly installed PAPI’s and demolished Taxiway R, was excavated to a depth of
5.6’ below runway surface. This excavation was necessary to remove silty soils that caused
frost heaving during winter. The excavation was backfilled with non frost susceptible classified
fill. Runway 16/34 pavement is in good condition and no signs of pavement heave or rutting
have been reported since the rehabilitation.
Taxiways. Taxiway pavements were tested by Alaska DOT&PF in 2009. The DOT&PF report
recommends ongoing preventative maintenance. Merrill Field implements ongoing preventative
maintenance using a crack sealing program to extend the life of its pavement. Taxiway
pavement was visually inspected by HDL in April 2007 and October 2007. The 2007 Annual
Airport Inspection Report identified eight (8) locations on Taxiways A, C, K, and N that
contained severely cracked pavement, poor drainage, or frost heaves. These areas were
rehabilitated in 2010 as part of the Rehabilitate Runway 16/34 project. The project rehabilitated
approximately 34,700 square feet of existing pavement and underlying subgrade. Pavement
was removed, subgrade soils were excavated to a depth of 4 feet, and the structural sections
were rebuilt with classified fill, leveling course, and pavement.
Taxiway Q was rehabilitated between Merrill Field Drive and Taxiway G in 2010 and 2011
during Rehabilitate Taxiway Q, Phase 1 and Rehabilitate Taxiway Q, Phase 2, respectively.
The rehabilitation consisted of pavement removal, new grading for positive drainage, new storm
drain system installation, dynamic compaction of the taxiway shoulders and adjacent apron
areas, and installation of new leveling course and pavement. This portion of Taxiway Q
pavement is in good condition since the rehabilitation projects and no signs of pavement
cracking or settlement are currently noted in this area.
Taxiway Q between Taxiway G and Alaska Regional Hospital is in fair condition and contains
settled areas that will need to be rehabilitated within the next 2 to 5 years. This section of
taxiway is functional because of the positive longitudinal grade. Aprons that transition into
Taxiway Q are showing signs of failure due to settlement of underlying refuse. Portions of this
area will be repaired during the Rehabilitate Taxiway Q, Phase 3 project scheduled for
construction in summer of 2012. This project will rehabilitate approximately 415 feet of Taxiway
G between Merrill Field Drive and Taxiway Q and 245 feet of Taxiway Q east of Taxiway G.
The remaining portion of Taxiway Q between Taxiway G and Alaska Regional Hospital should
be rehabilitated as funding becomes available.

Aprons. Paved aircraft aprons range from good to very poor depending on the location.
Aprons located over landfill garbage are performing the worst and include portions of Golf East,
Quebec, and Whiskey aprons.
Since 2007, the Block 5 Apron has been rehabilitated by a series of FAA grant funded projects.
These projects include pavement removal, dynamic compaction of subgrade and underlying
refuse, backfill, and new pavement. The Block 5 Apron is in good condition and no settlement
or cracking has been noted in the rehabilitated areas.
The Charlie South Apron was rehabilitated in 2009 to pave gravel aircraft parking areas and
provide positive drainage. The existing grade was compacted and new leveling course and
pavement were installed. No subgrade improvements were made during the repair. Minor
settlement of underlying, non-compacted, refuse has been noted since construction. The apron
pavement surface is still in good condition and the apron remains fully functional. Dynamic
compaction of the underlying landfill and subgrade would extend the life of the apron and
should be performed when funding becomes available.
The 2010 Rehabilitate Taxiway Q, Phase 1 project repaved approximately 4,070 square yards
of the Quebec apron, southeast of the intersection of Merrill Field Drive and Taxiway Q. The
existing pavement was removed and new leveling course and pavement were installed to repair
ponding areas. No subgrade improvements were made during the repair. The northern edge of
the Quebec apron received dynamic compaction during the Taxiway Q Rehabilitation, Phase 1
and Phase 2 projects. These portions of the Quebec Apron are in good condition. Dynamic
compaction is recommended throughout the remaining Quebec Apron when funding becomes
available.
The Rehabilitate Taxiway Q, Phase 3 is scheduled for construction in 2012. This project will
rehabilitate approximately 54,500 square feet of Golf East Apron. The remaining portion of Golf
East Apron should be rehabilitated as funding becomes available.
The pavement in the medevac apron is cracking and should be replaced.
Recommended Corrective Action
Apron improvements should be focused in apron areas constructed above the closed Merrill
Field Landfill. Dynamic compaction of the underlying refuse prior to apron reconstruction has
shown positive results and extended the life of rehabilitated pavement. Dynamic compaction
over remaining paved areas above refuse is recommended with priority given to the Golf East
and Q aprons, as funding becomes available. It is anticipated that these rehabilitation projects
will be phased over multiple years. The following corrective action summary includes pavement
in critical areas that need repair as soon as possible to improve safety and functionality at the
airport.

Instructions for Viewing Map Layers
The map contains layers, and must be opened with Adobe
Reader version 8 or later.
Click on Adobe's Layer Tab to
View Layer Controls
Click in a layer's box to turn it
on/off
The "eye" symbol shows that the layer is visible.
These layers draw from the bottom up, which means that a layer
higher in the list might block out the information on a lower layer.
Turn off the higher layer to see the information on a visible lower
layer.

2012 Updated Airfield Inspection Report
Airfield Signage
1.3 AIRFIELD SIGNAGE
Introduction
Ninety-eight (98) lighted and unlighted airfield signs were inspected on October 3 and 5, 2007
for condition and compliance with AC 150/5340-18D “Standards for Airports Sign Systems”. AC
150/5340-18D (the standard) provides recommendations for standardized airport signs and
should be followed to the greatest extent practicable.
FAA personnel at the Merrill Field Airport Traffic Control Tower (ATCT) were interviewed.
ATCT personnel reported that aircraft rarely become lost or disoriented in the Air Operations
Area (AOA) and few incursions have taken place where a pilot has failed to notice existing
signage. Most incursions occurred on the gravel Runway 5/23 where there is neither runway or
taxiway edge lighting nor lighted signs to provide guidance in poor visibility.
The 2007 inspection work included evaluation of signage for Runway 7/25, Runway 16/34,
Runway 5/23 (Runway 4/22 in 2007), Taxiways A, N, C, G, and Q, and interlink taxiways. Signs
were checked for compliance with FAA criteria including presentation, sighting criteria, height,
lettering size, and whether they were functioning. The signs included 63 lighted signs and 35
unlighted signs. An Inspection Checklist was prepared to evaluate the condition of each sign
and determine its conformance with AC 150/5340-18D and is included in this section. This
inspection checklist has been updated to include recent improvements constructed on Merrill
Field since 2007.
Since October 5, 2007, nine (9) Airport Improvement Program (AIP) projects have been
completed at Merrill Field Airport. Components of these projects have repaired and replaced
existing signage at Merrill Field Airport. Recent airport improvement projects that included
upgrades to the signage systems at Merrill Field are included in Table 1.3a below.

AIP # 3-02-0015-056-2011
Security Improvements, Phase 1
· New Rwy 5/23 unlighted signs (mandatory instruction, location, & boundary)
Merrill Field airfield signs are sized in accordance with Category 1 sign criteria listed in Table 2
of AC 150/5300-13. Category 1 signs have maximum height 30 inches above finish grade.
The signs inspected on Merrill Field contained 12-inch lettering and were between 28 and 30
inches high. The signs were installed 10 to 20 feet from the runway or taxiway edge in
accordance with AC 150/5300-13. Raising the height of existing signs would cause the signs to
exceed the Category 1 sign criteria standards. Signs that exceed these standards require
larger sign panels, printed with larger lettering, and installed farther from the runway or taxiway
edge to avoid contact with low-wing aircraft. The existing sign size and location meet the needs
of a general aviation airport. Installing larger signs farther from the runways and taxiways is not
recommended.

2012 Updated Airfield Inspection Report
Airfield Signage
The 2007 Annual Airport Inspection Report identified 19 airfield sign items that did not meet
standards and are candidates for corrective action. The airfield improvement projects
constructed since 2007 have addressed 10 of these items through construction of new
improvements or decisions to make no corrective action during final design. The FAA
regulations allow the Airport Manager to deviate from the standard where the standard signage
application is impractical or presents additional safety concerns or confusion. Locations and
explanations for noted items where no corrective action was taken are included in Table 1.3b
below.

Distance of Runway Hold

Reasoning For "No Corrective Action"
Determination
Hold position signs installed 125' from
Runway centerline would position holding
aircraft within the traveled ways of Taxiway
C and Taxiway K. The non-standard hold
position location is identified on the
approved ALP and Modification to
Standards letter dated February 10, 2009.

Recommended Corrective Action
The Updated Airfield Signs Corrective Action List, Existing Airport Sign Layout Diagram, and
Airfield Sign Inspection Checklist are included with this report. The Updated Corrective Action
List identifies 19 items that did not meet the standard and are candidates for corrective action.
No action was recommended on Items 1, 5, 6, 9, 10, 12, 13, 14, 15, 16, 17, 18, and 19 because
the existing sign configuration provides clear information to the pilot, and reconfiguration to the
standard would likely make information more confusing. The remaining 6 work items identified
on the checklist were consolidated into 3 corrective action categories. These corrective action
categories include fixing broken or missing signs, constructing new signs, and relocating
existing signs to standardize sign layout in the vicinity of the intersecting runways and taxiways.

1.4 AIRFIELD MARKINGS
Introduction
An airfield pavement marking inspection took place in October of 2007 and was reported in the
2007 Annual Airport Inspection Report. The marking inspection utilized a September 17, 2007
aerial photo of Merrill Field Airport provided by Aero-Metric, Inc. The photo was taken on a
clear day with the airfield pavement markings clearly visible. The photo was scaled using 2005
AutoCAD computer software to an accuracy of approximately 0.5 feet. The inspection
evaluated the existing runway and taxiway pavement markings for condition and compliance
with AC 150/5340-1K “Standards for Airports Markings”. In 2012, CAD Civil 3D 2011 was used
to verify marking locations utilizing an Aero-Metric, Inc. aerial photograph taken on October 4,
2011.
Since October 2007, nine (9) Airport Improvement Program (AIP) projects have been
completed at Merrill Field Airport. Components of these projects have rehabilitated existing
airport markings at Merrill Field Airport. Table 1.4a lists recent airport improvement projects
which included upgrades to the marking pavement systems at Merrill Field.

Runway 7/25 is a visual runway marked with precision runway markings. Precision markings
include threshold bars, threshold markings, runway designation markings, centerline and edge
striping, aiming points, and touchdown markings. The precision marking of this runway
exceeds the FAA standards for Merrill Field’s circling GPS approach. The runway also contains
lead-in chevrons on unusable pavement beyond the runway thresholds. The runway markings
consist of white paint. The chevron markings consist of yellow paint. The attached Updated
Airfield Marking Deficiency List indentifies that touchdown zone markings and aiming point
markings on Runway 7/25 are located approximately 20 feet down runway from the preferred
location listed in AC 150/5340-1K. In 2010, the Runway 7/25 markings were re-applied in their
current location to correct old and faded markings. Through discussions with the Owner, the
Page 1 of 3
Municipality of Anchorage
Merrill Field Airport
2012 Updated Airfield Inspection Report
Airfield Markings
decision was made to not relocate the aiming points and touchdown zone markings during the
2010 project because removal of the existing markings would damage the runway surface.
Also, the VASI’s, which are co-located with the aiming point markings, can be negatively
impacted when the markings are shifted. It is recommended the 7/25 marking configuration be
revaluated during the next 7/25 runway surface rehabilitation project and relocation of the
existing runway markings be performed at that time.
Runway 16/34 is marked with non-precision runway markings meeting the requirements of a
visual runway. The runway contains threshold markings, runway designation markings, and
centerline striping. Lead-in chevrons are installed on the unusable pavement beyond the
threshold of Runway 34. Aiming points, touchdown zone markings, and edge striping are not
required on Runway 34 because it is a visual runway less than 4,000 feet long with full width
available for aircraft operations. The runway markings consist of white paint. The chevron
markings consist of yellow paint. This runway was rehabilitated in 2010 to include new
pavement markings and lighting.
Paved taxiways are marked full length with centerline striping. Dashed edge striping is
implemented on taxiway edges abutting paved aprons. Aircraft hold position markings are
installed on interlink taxiways between runways and parallel taxiways and also prior to taxiway
gates and on Taxiways G and Q at intersections with parallel Taxiways N and C. Runway 16/34
hold position markings are located 100 feet from runway centerline, which is 25 feet less than
the standard distance specified in AC 150/5300-13. The hold lines are installed in this location
to keep holding traffic out of the traveled way of the parallel taxiways. The non-standard hold
position location is identified on the approved ALP and the Modification to Standards letter
dated February 10, 2009 and corrective action is not recommended.
Taxiway gate markings also include gate approach markings on the air-side pavement prior to
the gate location. Edges of roadways that intersect taxiways are delineated with dashed
“zipper” markings for enhanced visibility. “Zipper” roadway markings consist of white paint.
Taxiway centerline stripes, edge stripes, hold position markings, and gate approach markings
are installed with yellow paint.
Recommended Corrective Action
Removal and reinstallation of the Touchdown Zone and Aiming Point Markings is recommended
when funding becomes available or during the next Runway 7/25 pavement rehabilitation
project. The attached Updated Airfield Marking Deficiency List and Sheet 1.4 identify the
corrective action items and locations.

Access Road Pavement
2.1 ACCESS ROAD PAVEMENT
Introduction
The asphalt concrete (AC) pavement on Merrill Field Drive was inspected on October 4, 2007
for condition and compliance with the Alaska Department of Transportation (ADOT) and
Municipality of Anchorage (MOA) standards. The inspection work included evaluation of the
pavement along the Merrill Field Drive corridor. Pavement was checked for rutting, settlement,
heaving, cracks, potholes, raveling, and pavement wear.
Since October 4, 2007, nine (9) Airport Improvement Program (AIP) projects have been
completed at Merrill Field Airport. One (1) of these projects contained a component that
rehabilitated an existing paved area along Merrill Field Drive. Recent airport improvement
projects that include upgrades to Merrill Field Drive pavement are identified in Table 2.1a below.

Segments of Merrill Field Drive were rehabilitated during the summer of 2000 to repair
pavement damage from settlement of underlying landfill refuse. The project included
reconstruction of approximately 1,080 linear feet of road between Taxiway G and the UAA
Aviation Complex and approximately 3,200 linear feet of road near the south airport entrance.
The reconstruction of the area to the east of Taxiway G included removing existing road
structural section and performing high energy dynamic compaction of underlying landfill refuse.
Granular fill was placed over the consolidated refuse to re-establish crown and grade prior to
installing new AC pavement. Reconstruction of the road near the south airport entrance
included rotomilling existing pavement, placing of granular fill to re-establish crown and grade,
and installing new AC pavement. Dynamic compaction was not used in this area.
The 2007 pavement inspection revealed that the 1,080 linear feet of Merrill Field Drive to the
east of Taxiway G performed well over the course of the past 8 years. This area was
reconstructed using dynamic compaction to consolidate underlying refuse.
Very little
settlement, cracking, and rutting was noticed in this pavement section. However, settlement
and pavement cracking was witnessed in the area near the south airport entrance that was also
rehabilitated in 2000. Dynamic compaction was not used in the reconstruction of this area.
The performance of the pavement in this area indicates continued settlement of the underlying
soils from degradation, decomposition, and settlement of landfill refuse. Other pavement areas
not located over landfill refuse showed signs of wear after years of routine airport traffic, heavy
studded tire wear, and heavy construction vehicle traffic for airport improvement projects.

2012 Updated Airfield Inspection Report
Access Road Pavement
A 74 foot by 25 foot section of Merrill Field Drive near the end of Runway 34 was rehabilitated in
2009. Subgrade settlement of the road section caused a below-grade, abandoned, manhole to
differentially settle yielding an uneven driving surface. The pavement was removed, the
abandoned structure was completely demolished, backfill was compacted, and new pavement
was installed. Continued settlement in this area has resulted in slight grade changes since the
2009 work.
In 2009, two (2) new taxiway aircraft gates were installed on Taxiway G and Taxiway Q at
intersections with Merrill Field Drive. The existing asphalt was removed from the intersection to
perform conduit trenching work and traffic loop installation work. New leveling course was
installed, graded, and compacted. New pavement was installed. The pavement in these areas
is performing well since the work.
Recommended Corrective Action
Two airport access road rehabilitation projects are recommended based on the 2007 pavement
inspection. The first project is to rehabilitate 3,830 LF of Merrill Field Drive from Taxiway
Quebec to the intersection at 15th Avenue. Approximately 3,260 LF of this road section is
located above the old landfill. Dynamic compaction of the landfill waste is recommended in this
area to prolong the life of the pavement based on the results of the 2000 Merrill Field Drive
rehabilitation projects. Construction of this project would include removing the existing road
structural section to a depth of 3 feet, performing high energy dynamic compaction of
underlying landfill refuse, placing granular fill to re-establish crown and grade, and installing
new AC pavement. This project should be performed within the next three years to repair
damaged pavement areas that continue to degrade. The second project is to rehabilitate
approximately 1,900 LF of Merrill Field Drive from the intersection at Airport Heights Drive to the
limits of the 2000 Airport Access Road Rehabilitation Project. Approximately 450 LF of access
road to west of Airport Heights entrance is founded on good gravel and dynamic compaction is
not recommended. The remaining 1,450 LF of Merrill Field Drive is constructed above the old
landfill and dynamic compaction is recommended to consolidate the underlying refuse. Sheet
2.1 attached at the end of this section identifies the project locations. Construction methods for
the dynamic rehabilitation of the dynamic compaction areas and rehabilitation of the gravel
areas will be the same as described above. It is recommended that the remaining portions of
Merrill Field Drive be rehabilitated within 10 years.

2.2 SIGNAGE AND MARKINGS
Introduction
Road signs and pavement markings along Merrill Field Drive were inspected on October 4,
2007 for condition and compliance with the Alaska Department of Transportation (ADOT) and
the 2003 edition of the Manual on Uniform Traffic Control Devices (MUTCD). The inspection
work included evaluation of signage along the Merrill Field Drive corridor and at taxiway and
apron intersections. Signs were checked for compliance with presentation, reflective standards,
effective application, siting criteria, height, condition, and size. A deficiency list was prepared to
identify sign applications that fail to meet MUTCD and ADOT standards. This inspection report
was updated to included recent roadway signage improvements on Merrill Field Drive. The
updated road sign deficiency list is included at the end of this section.
Access road signage is an important component of airport safety and reducing runway
incursions. Informational and directional signs posted along Merrill Field Drive help direct
unfamiliar airport users to their intended destinations without inadvertent travel into the aircraft
movement area. Proper signage, used in combination with the established Merrill Field Driver
Safety Training Program, improves airport safety and security and reduces the risk of runway
incursions.
Since October 4, 2007, nine (9) Airport Improvement Program (AIP) projects have been
completed at Merrill Field Airport with impacts to signage along Merrill Field Drive. Components
of these projects have repaired and replaced existing signage at Merrill Field Airport. Recent
airport improvement projects that include upgrades to the signage systems at Merrill Field are
identified in Table 2.2a below.

In 2008 and 2009, the Alaska Department of Transportation and Public Facilities constructed
th
the 5 Avenue widening project adjacent to Merrill Field. The project widened the existing
drivable surface of 5th Avenue and installed a median between the east and westbound traffic
lanes. In order to widen the road, the Merrill Field Airport Frontage Road was eliminated and
four circular turnouts (Wilbur Circle, Ardaiz Circle, Reeve Circle, and Hudson Circle) were

2012 Updated Airfield Inspection
Security Gates and Fencing
3.1 SECURITY GATES AND FENCING
Introduction
Thirty-four (34) electronic vehicle gates, twenty (20) pedestrian gates, three (3) taxiway barrier
gates, and eight (8) non-electrical manual vehicle gates were inspected in October 2007 for
general condition and functional performance. A map of the gate locations is attached at the
end of this section.
Since October 4, 2007, nine (9) Airport Improvement Program (AIP) projects have been
performed at Merrill Field Airport. Components of these projects have updated portions of the
security gate and fence systems at Merrill Field Airport. Table 3.1a identifies a list of recent
airport improvement projects that included upgrades to the security fencing and gate systems.

In 2008 and 2009, the Alaska Department of Transportation and Public Facilities constructed
the 5th Avenue widening project adjacent to Merrill Field. The project widened the existing
drivable surface of 5th Avenue and installed a median between the east and westbound traffic
lanes. In order to widen the road, the Merrill Field Airport Frontage Road was eliminated and
four cul-de-sacs (Wilbur Circle, Ardaiz Circle, Reeve Circle, and Hudson Circle) were installed
to provide airfield access along 5th Avenue. This project relocated the fence alignment and new
vehicle gates were installed at the new airport access points.
The results of the HDL and Merrill Field maintenance staff 2007 inspections are contained in
the field inspection checklist located at the end of this section. The inspection reports and
checklists have been updated to consider improvements constructed since 2007.

2012 Updated Airfield Inspection
Security Gates and Fencing
Electronic Vehicle Gates. Electronic gate operator components were visually inspected
including the gate rollers, pinion shafts, chains, sprockets, gear boxes, fuses, power supplies,
key pads, manual overrides, motion detectors, heaters, edge sensors, and electric eyes. Merrill
Field maintenance staff independently inspected fuses, wiring, thermostats, timer clocks relays,
and limit switches in July 2007. There were no significant operational problems reported with
the electronic vehicle gates, other than edge sensors that were not functional. Poor edge
sensor functionality was likely due to dead batteries in the wireless unit. The gate map and list
of deficiencies has been updated to consider recent fence and gate upgrades constructed since
the October 2007 inspection. No additional field inspection or gate operation verification was
performed as part of this report update.
Pedestrian Gates. Components of twenty (20) pedestrian gates were inspected in October
2007, including the rollers, cables, combination locks, latches, grease fittings, and counter
weights. Most south, east, and west pedestrian gates were generally in good condition with a
few that need minor adjustments. Currently (June 2012), several of the north pedestrian gates
do not have controls installed (combo locks, automatic closers, handles, etc.) These north
gates were relocated during the ADOT&PF 2008 project and the controls were not re-installed.
The gates are locked with chains and pad-locks. Attached is an updated list of inspection
items.
Taxiway Barrier Gates. Taxiway barrier gates at Merrill Field are rolling cantilever-style gates
with mesh panels. The gates are in excellent shape and function properly. In 2010, two new
taxiway barrier gates were constructed at the intersection of Merrill Field Drive and Taxiway Q
and the intersection of Merrill Field Drive and Taxiway G. The taxiway barrier gate located at
the south end of Taxiway G was constructed in 2005. One square-tube structural member on
the east panel of this gate has split from water intrusion and freezing.
Non-Electronic Vehicle Gates. The condition of eight (8) non-electronic manual rolling gates
were inspected in October 2007. The non-electric vehicle gates were all pad-locked and
generally in fair to good condition with no deficiencies that would pose a security concern.
Fencing. Merrill Field operates and maintains approximately 28,200 lineal feet of airport
perimeter and internal security fencing. The north, east, and south perimeter fencing is typically
6-foot high. The west perimeter fencing, parallel to Orca Street and the Fairview community,
includes sections of 7-foot and 8-foot high fence. The perimeter fencing on the west side of the
field consists of either galvanized chain-link or vinyl coated fence meeting FAA material
specifications. The fencing is in reasonably good condition and no deficiencies were noted.
Recommended Corrective Action
Recommended corrective action includes: 1) repair non functional edge sensors, key pads,
and manual over-rides on the electronic vehicle gates, particularly the safety devices as soon
as practicable; 2) reinstall locking and automatic closure components on the pedestrian gates;
and 3) repair the damage aluminum tubing on the Gravel/Ski Runway gate, and drill weep holes

2012 Updated Airfield Inspection
Public Address System
3.2 PUBLIC ADDRESS SYSTEM
Introduction
The public address (PA) system was inspected in May of 2007 by HDL and Siemens Building
Technologies (Siemens) and was found to be not operational.
At the time of inspection, the airport’s existing PA system consisted of a transceiver located at
the FAA Airport Traffic Control Tower (ATCT) that transmitted to four loudspeakers located on
the south side of Runway 7/25. There were four existing loudspeakers – three pole-mounted
loudspeakers and one speaker mounted on the north wall of the Merrill Field Airport Manager’s
Office. The three pole mounted loudspeakers were driven by transceivers/amplifiers located in
weather-proof electrical boxes at the poles. The transceiver/amplifier on the pole located south
of the Airport Manager’s Office drove the loudspeaker on the pole and the loudspeaker on the
north wall of the Airport Manager’s Office.
The PA system is used by ATCT controllers to communicate directly to unauthorized vehicles
and pedestrians who inadvertently access the air operations area. Construction began in 2008
under AIP 3-02-0015-042-2007 to perform the following work to repair and improve the PA
system:

Base Transceiver: Replaced the base transceiver located on the roof of the FAA Air
Traffic Control Tower. Installed an uninterrupted power supply (UPS) at the transceiver
to limit disruption from power spikes.

Pole-Mounted Panel and Speaker Assembly Located Near UAA Building: Replaced
existing antenna, receiver, amplifier, and speaker and incorporated new components
with existing heater, cable, and conduit.

Pole-Mounted Panel and Speaker Assembly Located Near ACE Hangar Building:
Replaced existing antenna, receiver, amplifier, and speaker and incorporated new
components with existing heater, cable, and conduit.

Pole-Mounted Panel and Speaker Assembly Located Near Airport Manager’s Office
Parking Lot: Replaced existing speaker, installed new heater, and incorporated new
components with existing antenna, receiver, amplifier, cable, and conduit.

Speaker Assembly Mounted on North Exterior Wall of Airport Manager’s Office:
Replaced existing speaker.

Pole-Mounted Panel and Speaker Assembly Located in 1209 Orca St. Parking Lot:
Installed a new pole-mounted speaker assembly including speaker, pole, control panel,
antenna, power supply, and associated appurtenances in the parking lot of the 1209
Orca Street building. Replaced the existing meter base in the parking lot and connected
the new speaker assembly to the new meter base.

Video Surveillance System
3.3 VIDEO SURVEILLANCE SYSTEM
Introduction
The video surveillance system currently installed at Merrill Field represented the state-of-the-art
in video camera, wireless local area network (LAN), and video management software systems
in 2005 when the system was designed. Originally 63 analog day/night capable cameras were
placed at strategic positions around the airfield with video from these cameras stored digitally
for a 30-day minimum period on servers located at the airport management office. Most of the
cameras are connected into the system using a point to multi-point wireless LAN internet
protocol (IP) radio network system. The video management software was provided by Verint
Loronix and runs on a Verint proprietary digital video recorder (DVR) hardware based platform.
A public web page is provided for the viewing of camera still frame images which are updated
every 5 minutes. The video surveillance system was installed in years 2005 and 2006 and is
still in operation.
The camera system was not inspected during the 2007 Annual Inspection Report because the
system was newly installed and actively maintained by separate security camera specialists.
Since 2007, the system has become increasingly unreliable and has many obsolete parts that
cannot be repaired or replaced. The LAN is using wireless technology that is operating at its
maximum data throughput capacity at all base station locations, severely compromising the
overall system performance and stability. The analog cameras installed are 5 years old and are
not providing acceptable video resolution. In addition, the Verint Loronix video management
software currently used is no longer supported by the manufacturer, and does not provide an
internal supervisory function to automatically identify system faults such as loss of camera video
input. Loss of camera video data has routinely gone for months before it is identified and
repaired. All DVR and computer hardware used in the video management and display system
is reaching end of life and is no longer supported by the manufacturer.
HDL inspected the existing video surveillance system in April and June of 2011. The system
was found to be working, but with an unsatisfactory level of reliability and video camera
resolution. Camera video data inputs are often unknowingly lost for months at a time and
frequently computer and wireless LAN components must be restarted to reacquire camera
transmissions. Cameras that have failed or gone off-line with no video provided are typically
only identified when a system user tries to view that specific camera and then notifies airport
personnel of a failure. The system originally consisted of 63 cameras as shown in Drawing E1.0
attached. The condition of each camera is noted in the attached Merrill Field Camera Inventory
dated June 15, 2011.
The wireless LAN system was found to be operating at its maximum data transmission capacity
at all five radio sector base stations, and as a result all camera frame rates have been locked at
a 1 frame per second and camera video encoder MPEG4 compression rates are set very high
to stay within the stable data rate capacity of the LAN. The wireless LAN system is also being

Video Surveillance System
used to support 33 gate access control systems widely dispersed around the airfield. In order to
provide a line of sight radio path for all of the gate control wireless subscriber units, a second
wireless base station location was added at the rotating beacon tower to support two 120
degree wide radio sectors. All beacon tower wireless LAN data is then sent via a single
subscriber unit to the airport traffic control tower's (ATCT) south facing base station. All
wireless base station data received at the ATCT is transmitted to the LAN server system via a
buried fiber cable between the ATCT and the airport manager’s office building.
Recommended Corrective Action
A system upgrade is required to provide Merrill Field with a reliable, low maintenance,
supportable and high resolution video surveillance system. The video surveillance market has
grown substantially since 2005 and several new “open architecture” video management
software systems, cost effective IP-based high definition (HD) cameras and fiber or wireless
high bandwidth LAN systems are available to meet or exceed the requirements of the Merrill
Field security camera system.
A significant investment was made in 2005 to install the current video surveillance system and
every effort should be made to carry forward as appropriate those cameras and system
components that are still supported by the manufacturer and have more years of useful lifetime
remaining.
In order to determine the scope and design parameters of the recommended video surveillance
system upgrade project, a field test of possible camera and video management systems was
performed in February 2012. The purpose of the field test was to evaluate under realistic day
and night winter operating conditions the capability of four candidate outdoor rated HD
Megapixel cameras and security software to capture vehicle images and vehicle license plate
information. The field test cameras were located at the Lake Otis Parkway entrance and at
Merrill Field Drive exit. Specific emphasis was placed on achieving adequate video resolution
for consistent vehicle and license plate capture images during both day and night low light
conditions. Four HD Megapixel cameras from top manufacturers, installed in their respective
manufacturer provided weatherproof exterior housing, were evaluated. The High Definition
Video Camera Field Test and Evaluation Report, dated April 3, 2012 is included at the end of
this section.
AS a result of the inspection and subsequent field test program, a phased overhaul of the
existing video surveillance system at Merrill Field is recommended. The following system
upgrades are needed:
1. LAN Upgrade: Existing wireless LAN should be replaced with fiber-based LAN to
increase reliability and performance of the video surveillance system.
Page 2 of 4
Municipality of Anchorage
Merrill Field Airport
2012 Updated Airfield Inspection
Video Surveillance System
2. HD Camera Upgrades: The existing analog cameras should be replaced with new HD
cameras and new cameras should be installed at strategic locations to improve
surveillance footage of vehicles and a pedestrians entering and existing the airport.
3. Hardware: All of the remote Netgear hardware LAN switches are of limited temperature
range consumer quality and need to be replaced with a more reliable industrial quality
LAN switch such as those manufactured by Garrettcom. This will contribute to improved
LAN performance stability. Also, all currently installed video management hardware is at
end of life and should be replaced with a current production rack-mount server class
computer running the Microsoft Server Class Operating System. An external hard drive
RAID 5 storage array should also be provided to support the requirement for a minimum
of 30 days video storage from all camera systems including the 4 new HD camera
systems.
4. Video Management Software Upgrades: The Verint Loronix video management software
should be replaced with open architecture state-of-the-art video management software.
It is recommend that the work described above be constructed in four phases as funding
becomes available. Sheet E1.1 attached to the end of this section shows a conceptual phasing
plan for the video surveillance system upgrades. Sheet G1.3 attached to the end of this section
shows the scheduling for the first phase of construction. The first phase was designed in spring
2012 and construction is scheduled to be complete in early summer 2013. The 2012 security
improvement project includes the following work:
1. A complete fiber optic cable LAN backbone along Merrill Field Drive, including
approximately 10,600 feet of buried fiber optic cable, innerduct, distribution centers,
patch panels, splice enclosures, connectors, jumpers, and junction boxes.
2. A video surveillance network system including power-over-Ethernet (POE) managed
Ethernet switches, routers, video management server, analog camera video encoder
replacement, video management workstation, RAID 6 Hard Drive storage arrays, power
supplies, software, and equipment racks as required for a complete video management
system that seamlessly integrates with the existing video surveillance systems.
3. Video surveillance camera systems including infrared (IR) illuminators, camera
enclosures, supports, power supplies, transformers, surge arrestors, circuit breakers,
miscellaneous support equipment, and connections to existing power sources at the
locations shown on the drawings.
4. Network connections to two existing vehicle access gates including any required
configuration or software changes.
5. Complete integration with the existing video image web server system, and other related
work.

Purpose
The purpose of this field test was to evaluate under realistic day and night winter
operating conditions the capability of four candidate outdoor rated High Definition (HD)
Megapixel cameras and security software to capture vehicle images and vehicle license
plate information when located at the Lake Otis Parkway entrance and exit at Merrill
Field drive. Specific emphasis was placed on achieving adequate video resolution for
consistent vehicle and license plate capture images during both day and night low light
conditions. Four HD Megapixel cameras from top manufacturers, installed in their
respective manufacturer provided weatherproof exterior housing, were evaluated.
The test cameras and software were evaluated for their overall performance in winter
weather conditions at Merrill Field starting on January 23, 2012 with initial data
recording through January 28. All cameras were left powered and in place for additional
video recording availability through the end of the month of March, 2012. The cameras
were specifically set up and evaluated for; vehicle image clarity, license plate capture
video quality, the ability to resist frost or fog on the all weather housing viewing window
and internal camera lens, consistent operation through low temperature weather
extremes, and the ability to maintain image focus through Day/Night winter weather
extremes. An external IR Illuminator was also evaluated to determine if this additional
illumination technique provides any advantages in license plate capture images during
low light night conditions.
The results of this field test will provide the required operational experience in the Merrill
Field Day/Night winter environment to assist in specifying the HD Megapixel camera
features and characteristics and software that are required to achieve the license plate
capture performance objectives of the video surveillance system.
1.1
Test Summary
State-of-the-art HD Megapixel cameras were obtained from the following leading
manufactures; IQinVision, Axis, Bosch, and Sony. Milestone XProtect, Corporate
edition, software was selected and used to operate the cameras and record video data.
Each camera was mounted in the manufacturer’s best available all weather outdoor
housing rated to – 40°C if possible. The cameras were all powered from a hardened
POE Ethernet LAN switch provided by Comnet. Only two of the cameras required an
additional power source connection for internal auxiliary heating; Bosch and Sony
(mounted in a Dotworkz housing). Each camera was fitted with an appropriate lens for
an achievable field of view of 30 feet wide at a distance of 80 feet.
All four cameras were mounted using their manufacturer provided wall mounts to a 4foot tall, 8-inch wide, test mount fixture made from ¾-inch plywood. The test mount
fixture was strapped to the light pole at four places for secure attachment. An outdoor
rated enclosure was provided with 120 VAC power to house the Comnet Local Area
Network (LAN) Power Over Ethernet (POE) switch and the 24 VAC transformer to
power the Bosch camera housing auxiliary heater. The cameras were mounted at a
1
height that provided essentially the same look angle to the target area. All camera
mounting and vehicle observation geometries are defined in Section 3.0.
The IR Illuminator was used during several night test periods. The IR illuminator was
placed on the ground approximately 40 feet from the vehicle capture area of
observation. Recorded video clearly shows the benefits of using an IR Illuminator.
A 100 foot long CAT 6 LAN cable was used to connect the Comnet LAN switch to a Dell
E5400 laptop positioned inside a minivan vehicle parked to the side of the light pole. All
four cameras were sharing the single Comnet 8-port POE LAN switch and
communicating to the laptop over a single Ethernet Cat 6 cable. No connection to the
Merrill Field LAN or the Internet was available or provided for this test. Milestone
software was used in the Dell Laptop for all video recording and viewing. The Milestone
software was configured to present a 2 X 2 camera display such that all 4 cameras were
viewed and recording video simultaneously for every vehicle observed.
Video was recorded for the day and night periods of January 23 through January 28,
2012. The cameras were left powered ON and available for additional video recording
as required using the laptop connection during the period of January 29 through the end
of the month of March. For the purposes of this report, only video recorded during the
January 23 through January 28 time periods will be presented since the test is still
ongoing during the writing of this report. All video data was recorded and saved to the
Dell laptop hard disc. Select video files showing the typical performance of the four HD
cameras are provided on a CD ROM which accompanies this report. The screen shots
in this report are a representative sample of the performance of the camera systems
under Merrill Field’s actual site conditions.
During the January 23, 2012 through January 28, 2012 test period; the outdoor ambient
temperatures ranged from a high of +10 F during daytime hours, to lows of – 16°F
during nighttime hours. Light snow was experienced during the nighttime hours of
January 25 and 26. The humidity was typically between 30 % and 40%.

Equipment Installation Descriptions
All four cameras were mounted to a 4-foot tall by 8-inch wide ¾-inch plywood mount
fixture using the camera manufacturer supplied wall mount brackets. The plywood
mount fixture was painted gray to match the color of the light pole. The fixture was
attached to the light pole using four band mounts. The cameras were mounted at the
height above ground as shown in Figure 1.0
The support box at the bottom was provided by Merrill Field and had two AC outlets for
120 VAC power. The Comnet POE switch, Comnet power supply, and the 24 VAC
transformers were installed in the support box. No heat source was provided in the
support box.
The IQinVision and Axis cameras only required power as supplied by the standard
Ethernet POE power source. The Bosch camera required Ethernet POE power for the
camera, and an additional 24 VAC at 40 VA for a thermostatically-controlled heater in
the camera housing. The Sony camera was mounted inside a Dotworkz housing that
required Ethernet POE power for the camera, and an additional 120 VAC at 50 VA
connection for the internal heater and 2 internal fans. The IQinVision and Axis cameras
do not provide an external power connection option for auxiliary heat in their housings
3.1
Camera Mounting and Positions
In order to provide the required Day/Night resolution for robust vehicle and license plate
capture, the cameras were set up to view a rectangular “box” capture area that
concentrated the camera image horizontal pixels per foot to a minimum of 45 pixels/foot
density over the front area of the vehicles moving through the capture area. An
observed capture area was established where the front of the car would enter into the
screen at the top left corner and exit at the lower right corner in order to maximize the
time that the vehicle and license plate are in the observed area, and to capture the
entire vehicle image including the windshield area to view occupants inside the vehicle.
In order to accomplish license plate capture, the look angle of the cameras relative to
the center front of the vehicle is very important and must not exceed an angle of 30
degrees in either the vertical or horizontal axis. Look angles of no greater than 30
degrees will reduce the relative motion of the license plate to the camera, and will thus
permit longer camera shutter speeds with minimal motion blur.
The cameras were mounted at a height where the look angles into the center of the
capture area were 16.5 degrees in the horizontal angle, and 9 degrees in the vertical
angle. The range to the center of the capture area was 79 feet. The capture area was
set up to emphasize the approaching lane, however the capture did cover the majority
of the opposite lane with very successful license plate captures on vehicles moving in
the opposite direction. See Figure 1.0.

Test Results
All four cameras were set to observe the identical capture area. It was determined that
the Sony camera did not have the correct lens and could not be focused properly to the
desired capture area. A replacement lens from the local Sony distributor was obtained
on January 26 to correct the problem; therefore the Sony video capture prior to January
26 will not have the correct close-in capture area view.

All cameras were adjusted individually for best focus and optimum day/night
performance. A substantial amount of time was spent working with each individual
camera to reach optimum performance for both day and night lighting situations. Prior
to this field test, I received specific instructions from each camera manufacturer for
setup procedures and optimum settings to achieve best performance for the moving
vehicle license plate capture. The day (color)/night (monochrome) mode change was
set to the best available automatic function as would be used in the Merrill Field
application. Each camera video output was set to MJPEG as sent to the Milestone
software for recording.
The Dell E5400 laptop was running the Milestone Corporate video management
software. Both the Milestone Server software and the Milestone Client viewer software
were running on the single Dell laptop. All cameras were configured to provide a
minimum frame rate of 15 frames per second to the Milestone software. It was found
that the laptop CPU utilization was 100% when both the Milestone Server and Milestone
Client viewer were in use at the same time during periods of live video capture. This
resulted in the Milestone software not recording every video frame provided by the
cameras. Once this problem was identified, the client viewer was used only after a
video capture period and this corrected the missing frame recording issue.
Approximately 50 hours of test video were recorded using a test vehicle driven by Roy
Pace of EDC, plus random vehicle traffic was recorded to provide a wide range of
vehicle types and speeds under Merrill Field’s ambient light conditions. All cameras
operated simultaneously and video from all four cameras was recorded simultaneously
for a direct comparison of each camera’s performance for exactly identical situations.
The cameras were all carefully focused and had no trouble maintaining the set focus
through the cold temperature extremes experienced (+10°F to –16°F) during the test
period. The remote back focus feature provided in the Axis, Bosch, and Sony cameras
was noted to be of high value and is considered to be an important “must have” feature
that will optimize camera performance over time, and will significantly reduce installation
and maintenance costs.

enhancement of the nighttime license plate capture image for all of the cameras. In all
cases, the Bosch camera provided the best night image performance both with and
without IR Illumination. Analysis and recommendations are provided in Section 5.

Analysis and Recommendations
All four of the cameras and software performed reliably during the test period. No
problems were encountered with the humidity, snow, and low temperatures
experienced. All cameras in their respective housings maintained a clear housing lens
and consistent video performance. During the 5-day data acquisition period, over 100
vehicle captures were collected, and 30 specific test vehicle video captures were
collected and analyzed. After review of all the collected video, the following analysis
recommendations can be made.
1. Provide a pixel density of at least 45 pixels per foot. In order to provide
acceptable license plate and vehicle image capture performance, the camera must
be setup at a range of about 80 feet, and with a horizontal field of view of 35 feet to
achieve a minimum horizontal video pixel concentration of 45 pixels per foot. It is
generally accepted in the industry that a minimum pixel concentration of 45 pixels
per foot is required in order to read a license plate. The camera must be setup to
concentrate the video pixel density into an area where vehicles pass through, and
the observation look angles must be no greater than 30 degrees in both the vertical
and horizontal planes. In order to accomplish this, the license plate capture
cameras must be; (1) selected with the correct megapixel performance, (2) fitted
with the correct lens to set the field of view, (3) mounted at a low height that is close
to the road surface, and (4) mounted at short range with sufficient width to capture
2 lanes of Merrill Field Drive.
When the camera horizontal pixel count (HPC) performance is known, the pixel
density per foot (PD) for a given field of view (FOV) is defined as follows:
PD = HPC / FOV
Looking at this another way, in order to determine the achievable field of view (FOV)
from a camera with known horizontal pixel count (HPC), and desiring a 45 pixel per
foot density for license plate capture, we can calculate the achievable FOV as
follows:
FOV = HPC / 45
Setting a capture area with a horizontal field of view of 35 feet, at a center range of
79 feet for this field test, the horizontal pixel density achieved with each of the test
cameras is calculated as follows;

All test cameras were adjusted for a capture area of 35 feet width at a range of 79
feet which exceeds the minimum requirement of 45 pixels per foot for license plate
capture.
All test cameras were setup as defined in Section 3.1. Each camera was carefully
adjusted for the correct capture area and the focus adjusted. The Axis camera was
provided with a lens that would not zoom to the exact same capture area at a range
of 79 feet and the capture area was moved slightly forward with a slightly greater
look angle to establish the correct field of view. The Sony camera was initially
provided with the incorrect lens. The correct lens was provided on January 26
establishing the correct capture area.
2. Provide Bosch NBN-832V-IP cameras. After careful review of all video captures,
the Bosch model NBN-832V-IP camera was the only camera that could consistently
capture license plates in both day and night conditions. See the typical video
captures provided in Sections 4.1, 4.2, and 4.3, and Table 2.0 below.

The IQinVision camera was second in license plate capture performance and the
Sony was generally slightly better than the Axis camera. The Bosch camera has a
more consistent performance in both day and night conditions and this is mostly due
to the Bosch internal proprietary camera and video processing designs, and the
specific Bosch optics developed for this camera series. The Bosch camera at 2.1
Megapixel has a potentially greater sensitivity to low light conditions; however this
can only partially explain the improved performance at night.
The Bosch camera was also easy to use and the menu and setup procedures were
simple and clear. No significant effort was required to get outstanding video license
plate capture performance. In the low light night conditions, the shutter speed of the
Bosch camera was reduced to 1/500 second to remove any motion blur from
vehicles moving at speeds up to 40 mph. This 1/500 shutter speed was also
acceptable during daylight conditions. It was noticed that with the shutter speed of
1/500 second not being a harmonic multiple of the 60 Hz line frequency, the night
video from the Bosch camera had a set of rolling horizontal hum bars in the video.
This is due to the street light amplitude moving up and down at a harmonic of the
line frequency beating with the fast camera shutter speed that is not harmonically
related to the 60 Hz line frequency. This effect, while a nuisance, did not reduce the
ability to resolve the license plate capture.
14
The IQinVision camera performed second best with inconsistent license plate
capture during the daytime hours. At night, the license plate capture was not
consistent in most cases with the headlights causing a “blooming” effect that
obscured the license plate information. Also, the license plate capture video was
typically blurred at night and could not be read. Daytime license plate capture was
fair, however blurred video was also a problem with the moving vehicles in daylight
conditions. The IQinVision camera did not have a remotely operated back focus
option; however this option is now available in the current camera models. Manual
focus of the camera was easily achieved and was stable during both day and night
video captures.
Both the Axis and Sony cameras provided similar performance. License plate video
capture was mostly possible only during the daytime hours and rarely possible at
night.
3. Provide Milestone open-architecture software. The Milestone XProtect,
Corporate edition, software was identified as the only complete solution for the
Merrill Field system for the following reasons:
a. Supports active fail-over to a second operating backup server PC for
automatic PC hardware fault tolerance without loss of system function or
data.
b. Has open architecture for hardware system optimization and reduced cost.
c. Interfaces to all cameras and video encoders planned for Merrill Field.
d. Supports over 100 simultaneous HD IP video cameras.
e. Supports ONVIF and PSIA standards.
f. Multi-stage storage features allows setting multiple archive steps with
individual retention times and frame rates to reduce cost of long term
storage.
g. Provides automatic camera loss of video detection and automated system
fault alarms with email notifications.
h. Alarm manager feature consolidates alarms from all security devices and
systems.
i.
Separate client viewer software runs on independent network to preserve
LAN bandwidth on camera network.
j.
Sequence explorer feature provides an instant overview of recorded video
and bookmarked incidents from multiple cameras, which speeds up
investigation work and simplifies evidence export.
15
k. Overlay buttons provide control, configuration, and maintenance functions
of cameras and devices directly from the camera view image.
l.
Manufacturer training course available for certification of system
integrators and installers.
4. Provide two cameras at gates. In order to improve the video capture, it is
recommended that two cameras be used at all license plate capture positions; one
camera looking at one direction and another camera at the identical mounting
height looking at the opposite direction, all at appropriate capture areas over the
road surface. This is fully defined in section 5.2.
5. Provide IR Illumination at gates. The use of the IR Illuminator at night to increase
the reflected energy from the license plates improved low light license plate capture
performance. A single IR Illuminator is recommended with each camera dedicated
for license plate recognition use. It was found that the use of an IR Illuminator
operating at a wavelength of 850 nM was quite helpful. The IR Illuminators would
be mounted at the same pole locations as the two license plate capture cameras.,
however at a lower height of 6 feet or less. Using two recommended Bosch
cameras configured in this way, nearly 100% license plate capture can be achieved
in daylight conditions and at least 90% license plate capture in the low light
nighttime conditions.
6. Provide ambient light at gates. Ambient street lighting at night is mandatory and
must be provided. The more street lighting there is, the better the nighttime video
license plate capture will be. Using IR Illumination alone is definitely not considered
adequate for the nighttime low light license plate capture.
7. Provide automatic back focus. The remote automatic back focus option was
extremely useful and is considered a “must have” feature. The remote back focus
feature will significantly reduce both the camera installation and maintenance times
required during the life of the system.
8. Camera placement and aiming. In order to accomplish vehicle license plate
capture video with adequate detail to digitally zoom to read the license plate
number, the cameras must be positioned with both a horizontal and vertical
maximum look angle of less than 30 degrees. In this field test, the cameras had
look angles of; 16.5 degrees horizontal and 9 degrees vertical. This will require that
cameras used for license plate recognition be mounted close enough and low
enough to the road surface to achieve these look angles. Cameras must also be
positioned at points where the vehicles are moving as slow as possible in order to
reduce image blur and obtain the maximum number of video frame captures
possible. Optimum camera placement positions are; curves in the road, stop signs,
and intersections. The video camera capture area should be adjusted to see the
vehicles in both lanes moving in both directions for each camera.
