Design Complexities
Integration/Implementation Plan
• FDOT and Broward County’s Plan for Arterial
Operations
GOAL OF THE PROJECT
Improve the efficiency of the existing Transportation
system through:
– Establish a System for Real Time Performance
Monitoring
• Detect the causes of non-recurring congestion
• Understand the recurring congestion patterns
– Active Arterial Management
• Incident management
• Traveler information dissemination
• Signal retiming
3
ATMS BENEFITS
• Increased motorists awareness of travel time and vehicular
incidents
• Emergency Pre-Emption and transit signal priority will allow
emergency vehicles and buses to travel faster, safer
• Improved incident response time through early detection
• Data collected used to adjust traffic signals to improve timing
and flow of traffic
• Reduced fuel consumption
• Reduced emissions
• Reduced accidents caused by congestion, speed differential and
sudden lane changing
• Reduced in secondary accidents
• Reduced delays
• Increased average travel speed
• Increased trip reliability

PROJECT AREA
ATMS IN CENTRAL BROWARD COUNTY
Project Components
– 31.8 miles of fiber optic
communication infrastructure
– Closed Circuit TV (CCTV) Cameras
– Arterial Dynamic Message Signs
(ADMS)
– Opticom devices for emergency
pre-emption and Transit Signal
Priority System (TSPS) devices
– Microwave Vehicle Detection
Sensors (MVDS)
– Travel Time System (TTS) readers
(AVI and Bluetooth)
Construction Timeline
• Summer 2012-Fall 2013
• COST: $8.9 million
• Contractor: World Fiber
Technologies, Inc.
• Lane Closures:
– Limited impact on the
communities surrounding
and within the project
limits.

existing mast arms)
Arterial DMS
AVI Travel
Time System
CCTV and
MVDS on Poles
and Existing
Mast Arms
DESIGN PROCESS
• Key MTR Requirements
– 100% CCTV camera coverage
– Cameras to be mounted on poles with lowering devices
• Providing complete camera coverage
– Bucket truck survey to replicate installed camera video.

DESIGN COMPLEXITIES
New DMS locations
TT Detectors and MVDS locations
• MVDS midblock spacing
• Travel time sensor spacing at origin and destination
points (also at DMS locations)
DESIGN PROCESS (CONT’D)
• Design variation was required due to mounting proposed CCTV
cameras on existing trusses and mast arms
– Structural analysis required on existing mast arms selected for camera
mount per PPM 25.4.26
• Release of underground conduit and pull box component plan
set to expedite construction.
DESIGN PROCESS (CONT’D)
• Utility Coordination with numerous utility owners
• Proposed device locations do not interfere with existing
overhead and underground utilities
– Design and construction Subsurface Utility Engineering (SUE)
investigation was utilized to achieve this.
• Verification of existing fiber optic infrastructure to connect with
the proposed ATMS network
DESIGN PROCESS (CONT’D)
• Co-locating ATMS devices where feasible to reduce
construction costs
• Permit approval process with local permitting agencies
INTEGRATION AND IMPLEMENTATION
• SunGuide to run ITS devices
– Developed new plugin for BlueTOAD travel time and
origin destination reports (provides real time input into
SunGuide for TMC operators)
– AVI module to be used in conjunction to compare
technologies
– New H.264 video stream driver
– All ITS devices are to be integrated and tested in
SunGuide
• Signal System is separate
– Opticom integrated into signal system

LESSONS LEARNED
• Device location acceptance before substantial design starts
• Underground conduit and pull box component set was
released to start construction
• Double stack concept plans not preferred, little room for
details
OPERATIONS AND MAINTENANCE OF ATMS:
AFTER ATMS IS COMPLETE, NEXT STEPS
• Fall 2013
• Partnerships – FDOT and Local Agencies
– Capitalize on strengths and pool resources
• Master Plan for Defined Network
• Development of Arterial Management Process
– Palm Beach County Living Laboratory
– Research projects
PARTNERSHIPS
• Operations and Maintenance
• Agency strengths and resources to be pooled for
maximum efficiency
• In house skills, ITS devices and ATMS software
• Investigate ways for FDOT District 4 to enhance arterial
O&M programs
• Objective – performance based arterial O&M program
1. Method for reporting
demand is defined
2. Identify
Critical Trends
3. Identify demand
Thresholds
4. What can we do to prevent
/alleviate network breakdown?
When should these strategies
be implemented?
Demand Based Signal Retiming
5. How do
the
strategies
impact the
network?
6.Demonstrate
18
PARTNERSHIPS
• Research underway in which
local agencies co-manage with
FDOT
– Demand Based Signal Retiming
– Coordinated Pre-Preemption of
Traffic Signals to Enhance
Railroad Grade Crossing Safety
in Urban Areas and Estimation
of Train Impacts to Arterial
Travel Time Delay
• Both focus on using existing
tools (signal system, system
software and data collection
devices)

EXPANSION OF ATMS ON A DEFINED
NETWORK
• Freeway ITS + Arterial ATMS
• Partnership with local agencies

PALM BEACH COUNTY LIVING LAB
• The principle goal for the TSM&O “Living Laboratory” is to
begin the utilization of TSM&O principles in a controlled
environment for a limited number of arterial roadways in
order to identify key elements and the requirements of the
process.
• Accomplished through PBC and FDOT partnership
• Primary Deliverable: Scalable SOGs that can be applied in
Broward County
PALM BEACH COUNTY LIVING LAB
• Starting with a plan with clear objectives and
targets
– Sample:
TSM&O Living Laboratory in Palm Beach County
OBJECTIVES
Define Scalable
Standard
Operating
Guidelines for
Active Arterial

Management
ACTIVITIES
1. Establish a monitoring plan to allow for TSM&O
operator to provide initial notification to the
County (example, cameras are reviewed every
hour). Performance metrics are defined as
possible.
2. Analyze the scalability of the monitoring plan
3. Document findings and Recommendations for
improving the monitoring plan for automation on
daily logs
4. Analyze daily logs and establish performance
targets
5. Daily analysis of problem areas and
recommendations are made for improving
performance and automating analysis of problem
areas
TARGETS (%, Score,
Timeframe,etc)
1. Initial plan developed
and implemented by
September 28th, 2012.
Plan improvements are
recommended by operator
in bi-weekly meetings.
2. To run concurrent with
development of
operations contract February 1st, 2013
Steps 3 - 5 are
documented in Daily Logs
and are reviewed in
weekly status meetings.
