Appendix D – System
Descriptions
Appendix D provides the reader with a background on the systems used
to illustrate CM concepts and practice throughout the handbook.
Southern California Priority Corridor
The Southern California Intelligent Transportation Systems Priority
Corridor is the site of a large integration effort involving multiple
ITS systems. As one of four corridors identified by the 1991 Intermodal
Surface Transportation Efficiency Act, the objective of the Corridor is
to fully deploy and showcase ITS potential. The Corridor serves the counties
of Los Angeles and Orange, and the major urbanized portions of Riverside,
San Bernardino, San Diego, and Ventura counties. The program includes
a number of smaller projects, currently at various stages. Some of the
goals of the program include: increasing the safety of travel systems,
aiding in the development of intelligent vehicle development, and enhancing
the transfer of passengers and goods from place to place. The integration
is providing both transportation management possibilities as well as increased
traveler information services.
Georgia NaviGAtor
NaviGAtor is the intelligent transportation system for the Georgia Department
of Transportation and combines video monitoring and detection with emergency
response systems and public input. Based on information gathered through
the various sensors, the system formulates a response plan and then communicates
it to the public. One of the primary goals of NaviGAtor is to link the
central traffic management center to transportation control centers in
surrounding counties, the City of Atlanta and the Metropolitan Atlanta
Rapid Transit Authority, thereby providing an enhanced ITS capability
that serves more than 220 freeway miles. Some of the major features of
the NaviGAtor program are: the Motor Vehicle Emergency Response Team,
roadside accident investigation sites, traveler information kiosks and
free cellular incident response service.
Maryland Coordinated Highways Action Response Team II (CHART II)
As a cooperative program between the Maryland Department of Transportation
and the Maryland State Police, CHART, Maryland's Transportation
Management System, aims to improve real-time operations of Maryland's
highway system through its ITS component, CHART II. Specifically, CHART
II is designed to monitor traffic conditions and issue advisories to motorists
based on information gathered from speed detectors, loop detectors, cameras,
weather sensors and cellular calls from the public. The system utilizes
permanent and portable message signs to disseminate the information about
traffic conditions to the public. CHART II has a central statewide operations
center and local traffic operations centers. Data are stored at the nearest
traffic operation center and are retrieved by the statewide operations
center when needed. One of the goals of this configuration is to provide
redundancy in case of failure of a single site.
Richmond, VA Smart Traffic Center
The Richmond Smart Traffic Center is one of three STCs in Virginia with
the stated goals of:
- Local traffic and transportation operations and management in [the
Richmond] district.
- Regional traffic incident and coordination within coverage area.
- Coordination with nearby STCs and/or transportation emergency operations
centers for regional or statewide transportation operations and incident
management.
The Richmond STC uses sources such as police, VDOT offices, and other
emergency responders to provide highway incident information to the 4
cities and 14 counties in the Richmond district. Some of the hardware
that the system employs includes: variable message signs (VMSs), highway
advisory radio (HAR), portable message signs, and closed-circuit video
cameras. The system operates 24 hours a day, 7 days a week.
