Mr. Conahan has extensive experience in various aspects of Traffic
Signals and Traffic Engineering, from planning and design to construction
and testing, and has knowledge of all federal and state standards required
for such projects. Specific aspects of planning and design include design
of traffic signals, capacity analysis and simulation, interconnection and
coordination of signal networks, safety studies, construction cost
estimation, specification preparation, construction services, highway
occupancy permitting, utility coordination, and data collection. He worked
for over 9 years with the Pennsylvania Department of Transportation
Engineering District 6-0 Traffic Unit. During his tenure with the Department
he was accountable for the contract, municipal, and system elements of
nearly 6,000 traffic signals, 160 signal systems, and 4 ramp metering
locations within the five-county Greater Philadelphia area.
Relevant Project Experience
Pennsylvania Department of Transportation Central Office, Traffic
Signal Asset Management System (TSAMS), District 6-0 : Responsible
for the documentation acquision, upload, and field inventory of 2,498 traffic
signal cabinets’ controllers, MMUs, detection equipment, preemption
equipment, and other relevavant components using an application in the
field to documents all manufacturers and system types into TSAM’s iPad
application. Once data is field logged, verifying and cleaning data in the
SharePoint database to ensure statewide consistency with overall
consultant team.
Upper Uwchlan Township, Adaptive Signal Control System, S.R.
0100, ARLE-Funded Project, Upper Uwchlan and Uwchlan
Townships, Chester County, PA: Project Manager and Lead Project
Engineer for the county’s first adaptive signal control system on two
corridors at eleven intersections along PA Route 100 and Graphite Mine
Road. Responsible for the extensive coordination between stakeholders;
systems engineering, product selection, and design; capacity analyses
and simulation modeling for time-of-day, traffic responsive patterns, and
incident management timings; bid packaging and awarding; and
construction observation and administration for this high profile project.
This project was partially funded from the Automated Red Light
Enforcement (ARLE) Program, with total funds being $668,000. Creative
use of option and alternative bidding methods also allowed for installation
of video and radar detection at every intersection and uninterruptible
power supplies at key locations and for the reconfiguration of the
intersection of PA Route 100 and East Township Line Road to install a
southbound left-turn lane which greatly increased mobility and progression
along the southern section of the corridor. Travel time reductions of up to
27% were realized with the addition of the adaptive signal control system.
City of Philadelphia Streets Department, Citywide Traffic Signal
Retiming Initiative, Various Corridors, City of Philadelphia, PA: Traffic
Signal Task Leader for a $700,000 engineering contract to optimize the
operations of up to 21 corridors and 600+ signalized intersections in the
City of Philadelphia. Special considerations included pedestrian timing and
accommodation and development of effective timing plans for corridors
that are limited by the use of electromechanical controllers. B/C ratios over
90:1 were achieved in some locations.
Pennsylvania Department of Transportation Engineering District 6-0;
Traffic Signal and Safety Open-End Services Contract; E01254 and
E02599; Bucks, Chester, Delaware, Montgomery, and Philadelphia
Counties, PA: Assistant Project Manager responsible for the distribution
of traffic signal and safety assignments received by Department
personnel. Managed the assignments that were performed in-house,
including traffic signal permit plan, construction plan, and tabulation
preparation; capacity analysis; corridor retiming; and low-cost safety
improvements.
Greene Township, Walker Road Traffic Signal Project (S.R. 0081 Sec.
065), Greene Township, Franklin County, PA: Project Manager for the
preliminary design, final design, and construction services of two new
traffic signals at the northbound and southbound approach ramps to the
Exit 17 Interchange of I-81. Special considerations were necessary, such
as queue management on the ramp approaches to avoid spill-back onto
mainline I-81 and radar presence detection due to a history of fog at the
interchange. The project also involved the interconnection of these
signals with the existing closed loop system in the neighboring Borough of
Chambersburg and the ADA-compliant curb ramp design at the project
and adjacent intersections.
East Whiteland Township, U.S. Route 30 and PA Route 29 Corridor
Retiming Initiatives, East Whiteland and Charlestown Townships, PA:
Project Manager responsible for the development and field implementation
of optimized traffic signal timings at 20 intersections on two primary
arterials. Scope of work included data collection, field views of controller
assemblies and their operational status, preparation of capacity analyses
utilizing Synchro and SimTraffic for developing new timings, and
implementation and fine tuning of timings in the controllers.
Lower Providence Township, Main Street/Ridge Pike Incident
Management Timings, Lower Providence and West Norriton
Townships, Montgomery County, PA: Project Manager responsible for
the trip generation and capacity analyses for three (3) special incident
management timing programs for seven (7) signalized intersections. The
Main Street/Ridge Pike corridor is a major regional arterial that is a
preferred alternate route through lower Montgomery County when
incidents occur on I-76, US Route 202, and US Route 422. Also
coordinated with the Lower Providence Township Police Dispatch and the
Montgomery County Emergency Operations Center on determinations of
need for incident timings and implementation procedures via the
Township’s closed loop system.
Pennsylvania Department of Transportation Bureau of Highway
Safety and Traffic Engineering, Roosevelt Boulevard (U.S. 1)
Retiming Initiative, E00228, City of Philadelphia, PA: District Project
Manager who supervised the optimization and implementation of traffic
signal timings for 14 highly complex signalized intersections along the
northern third of the corridor. Conducted before and after travel time and
delay studies. Special safety considerations were given to the
intersections at Red Lion Road and at Grant Avenue due to rankings as
two of the top three most dangerous intersections in the United States.
Pennsylvania Department of Transportation Bureau of Highway
Safety and Traffic Engineering, Newtown Bypass (PA 332/PA 413/PA
532) Retiming Initiative, S.R. E00228, Lower Makefield and Newtown
Township, Bucks County, PA: District Project Manager who supervised
the development and implementation of traffic responsive operation for
eleven (11) signalized intersections along the five-mile arterial. Conducted
before and after travel time and delay studies. Special consideration was
given to emergency management due to the likelihood that the arterial
would be utilized during major incidents on I-95 and US 1.
Pennsylvania Department of Transportation District 6-0, Traffic
Signal Maintenance Contract, Bucks, Delaware, and Montgomery
Counties, PA: Project Manager who managed the preventive and
emergency maintenance of state-owned traffic signals and railroad
crossings. Also, utilized the contract to upgrade and turn back state-owned
signals to respective townships.
Pennsylvania Department of Transportation District 6-0, Schuylkill
Expressway Corridor Transportation Systems Management, E00215,
Montgomery & Philadelphia Counties, PA: Signal Systems Design
Engineer and major stakeholder as a member of the PennDOT District 6-0
Traffic Unit in this federally-funded project which optimized traffic signal
timings and installed closed circuit television (CCTV) cameras and
dynamic message signs (DMS) along key diversion corridors, such as US
1 and PA 23.
