•High Definition Messages


Integrated Traffic Management System•Autonomous (Operated with little user intervention)

•Condition Responsive (Time Delays, Reduced Speeds)

•Improves traffic flow through work zones and high traffic areas

•Real time information

•Wireless networked - always communicating


Networked Components

• Enhanced Dynamic Message Sign (EDMS)

• Supplemental Speed Repeaters (SSR’s)

• Central System Controller (CSC)

• Highway Advisory Radio (HAR) optional


Enhanced DMS Concept

• Located upstream of construction and providing real time information concerning:

•Lane closure•Traffic speed•Queue development•Delays•Other


Enhanced DMS Components

• DMS with communications capability• Queue detector(s)• Doppler radar (optional)• Roadside remote station (RRS)


Supplemental Speed Repeater (SSR) Components

• Gathers traffic condition data and/or serves as a communications repeater• Has a trailer or pole mounted power source (battery w/solar)

• Has sensors: queue, speed, etc.


Central System Controller

A PC that processes traffic data from RRS/SSR and selects appropriate DMS messages through algorithmic process.


Secondary Central System Controller (CSC)

A PC that has access to traffic data and displays the current traffic profile, perhapsto an emergency service agency.


Condition-Response DMS Message Templates

• Congestion Advisory• Delay/Diversion• Time Stamp

Example:

Condition5 minDelayAhead

ResponseSLOW TO45 MPHNOW

Light Congestion
