System
 A key element
of Montgomery County’s Advanced Transportation Management System (ATMS)
is the traffic responsive signal system. The County’s computerized signal
system started with 10 intersections in 1980 and now controls all of approximately
780 County maintained traffic signals. The ATMS is designed to interface
to the existing COMTRAC computerized signal system and can readily be adapted
to new traffic signal technology. County-wide traffic responsive operation
will be implemented in the near future.
System features include:
- Second-by-second traffic signal control and monitoring
- Traffic responsive operation
- Capable of controlling 1500 traffic signals
- 100 groups of intersections
- Capable of monitoring 3000 sampling detectors of various types
- Special event plans
- Time of day operation capable
- Manual control of intersections and groups when required
- Real-time geographic information system
- Graphical user interface
- Priority signal treatment of the County’s 250 bus fleet
BENEFITS:
- Traffic signal control and coordination:
- Decreases traffic congestion
- Increases rush hour travel speeds by 14-20%
- Decreases the number of rear end collisions
- Improves system’s efficiency and decrease delay by an estimated 17-37%
- Decreases the average number of vehicle stops resulting in a reduction
in fuel consumption and carbon monoxide emissions
- Improves incident and special event management
