IVHS Categories: ATMS

Advanced Traffic Management Systems (ATMS) involve the use of surveillance technologies (e.g. machine vision devices, sensors, and CCTV) and advanced communications (e.g. VMS, HAR, and personal communication devices) to maximize throughput and safety by doing the following:

  • Facilitating timely (e.g. real-time) detection of roadway incidents and providing warnings to motorists or dynamically redirecting traffic through the use of VMS, HAR, or in-vehicle navigation technology to avoid congested areas of the 
    road network

     
  • Implementing adaptive traffic signal timing that minimizes the number of stops and hence the delay on arterial roadways

     
  • Providing signal preemption services to priority vehicles (e.g. emergency vehicles) to avoid possible conflict with other traffic at roadway intersections

     
  • Implementing effective ramp metering scheme in order to minimize interference on mainline traffic

     
  • Implementing electronic toll collection (ETC) scheme involving the use of transponders

     
  • Implementing multi-jurisdictional traffic control centers to address regional traffic operations issues

     
  • Integrating and optimizing multi-modal transportation system (e.g. passenger vehicles, trucks, train, and buses) operations

     
  • Providing surveillance and detection systems that minimizes the misuse of high occupancy vehicle (HOV) designated facilities

     
  • Using electronic sensors (e.g. machine vision cameras), involving less intrusive installation and maintenance than traditional in-pavement inductive loop detectors, as vehicular presence and incident detectors

     
  • Using electronic sensors as defined above to identify empty spaces as a way of optimizing parking operations
