Advanced Traffic Management Systems (ATMS)
General Description:
Advanced Traffic Management Systems are primarily aimed at improving vehicular flows on highways, arterial roads, and other streets. These systems typically use a combination of technologies that count vehicles, measure speed, and/or categorize motor vehicles to provide information to computers that control and adjust signal systems.
Examples of this include the following:
- Traffic signals that adjust their timing to the flow of vehicles through an intersection
- Freeway ramp metering systems that improve the flow of vehicles onto congested highways
- Speed detection and video surveillance of roadways that improves incident response
Effects of Solution:
¨ Increase Passenger Throughput
þ Increase Roadway Capacity (Optimizes intersection use)
þ Manage System Efficiency (Minimizes delays of vehicles)
¨ Reduce Local Demand
Examples of Implementation:
No information available at the time of publication.
