National ITS Architecture Functional Requirements
associated with Richmond District Local Signal Centers:

Collect Traffic Surveillance
  1. The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
  2. The center shall maintain a database of surveillance and sensors and the freeways, surface street and rural roadways, e.g. where they are located, to which part(s) of the network their data applies, the type of data, and the ownership of each link (that is, the agency or entity responsible for collecting and storing surveillance of the link) in the network.
TMC Signal Control
  1. The center shall remotely control traffic signal controllers.
  2. The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
  3. The center shall collect traffic signal controller fault data from the field.
  4. The center shall implement control plans to coordinate signalized intersections, under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, emergency vehicle preemptions, the passage of commercial vehicles with unusual loads, equipment faults, pedestrian crossings, etc.
HRI Traffic Management
  1. The center shall collect highway-rail intersection (HRI) equipment operational status and compare against the control information sent by the center.
  2. The center shall collect incident information related to a highway-rail intersection (HRI), such as intersection blockages or crashes or equipment malfunctions.
  3. The center shall implement control plans to coordinate signalized intersections around highway-rail intersections (HRI), under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, equipment faults, pedestrian crossings, etc.
Traffic Maintenance
  1. The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
  2. The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.
  3. The center shall exchange data with maintenance centers concerning the reporting of faulty equipment and the schedule/status of their repair. Information exchanged includes details of new equipment faults, and clearances when the faults are cleared.
