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.
- 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 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 )
Roadway Basic Surveillance
- 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.
Roadway Field Device Monitoring
- The field element shall monitor the operational status (state of the device, configuration, and fault data) of connected sensors (such as traffic, infrastructure, environmental, security, speed) and devices (such as highway advisory radio, dynamic message signs, automated roadway treatment systems, barrier and safeguard systems, cameras, traffic signals, ramp meters, short range communications equipment, security surveillance equipment).
- The field element shall send operational status of connected field equipment to the maintenance center.
- The field element shall send collected fault data to the maintenance center for repair.
- The field element shall include a local interface that provides operational status and fault data for connected field equipment to field personnel.
- The field element shall include a local interface that allows field personnel to command diagnostic tests on connected field equipment.
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.
TMC Probe Information Collection
- The center shall collect traffic probe data from vehicles via roadside field equipment.
