FUNCTIONAL REQUIREMENTS

Collect Traffic Surveillance

  • The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for traffic data.
  • The center shall maintain a database of surveillance equipment and sensors and associated data (including the roadway on which they are located, the type of data collected, and the ownership of each )
  • The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
  • The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.
  • The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
  • The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.

Roadway Basic Surveillance

  • The field element shall return sensor and CCTV system fault data to the controlling center for repair.
  • The field element shall return sensor and CCTV system operational status to the controlling center.
  • The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.

Traffic Equipment Maintenance

  • The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for traffic maintenance data.
  • 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.
  • The center shall collect environmental sensor equipment fault data and send to the maintenance center for repair.
  • The center shall collect environmental sensor operational status.
  • The center shall collect and store CCTV surveillance system (traffic, pedestrian) fault data send to the maintenance center for repair.
  • The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.
  • The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
  • The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
