Collect Traffic Surveillance
- The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
- The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
Roadway Basic Surveillance
- 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.
- The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
- The field element shall return CCTV system operational status to the controlling center.
- The field element shall return CCTV system fault data to the controlling center for repair.
- The field element shall return sensor system operational status to the controlling center.
- The field element shall return sensor system fault data to the controlling center for repair.
Roadway Probe Data Communications
- The field element shall communicate with passing vehicles for traffic data link time calculations and send collected data to the controlling center; identification will be removed to ensure anonymity.
- The field element shall communicate with on-board equipment on passing vehicles to collect current vehicle position, speed, and heading and a record of previous events (e.g., starts and stops, link travel times) that can be used to determine current traffic conditions.
- The field element shall communicate with on-board equipment on passing vehicles to collect current status information and a record of previous events (e.g., temperature, wiper status, headlight status, traction control system status) that can be used to determine road and surface weather conditions.
- The field element shall communicate with on-board equipment on passing vehicles to collect vehicle trip information (e.g., origin and destination information, travel times) that can be used to support transportation planning.
- The field element shall aggregate and forward collected probe information to the center.
- The field element shall provide roadside equipment operational status to the center.
- The field element shall provide roadside equipment fault indication to the center for repair.
TMC Probe Information Collection
- The center shall collect traffic probe data from vehicles via roadside field equipment.
- The center shall collect operational status for the roadside probe data collection equipment.
Traffic Equipment Maintenance
- The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
- The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
