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, and send traffic images to the center for further analysis and distribution.
- 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.
Roadway Traffic Information Dissemination
- The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.
- The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
- The field element shall include driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers, under center control.
- The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
TMC Traffic Information Dissemination
- The center shall provide the capability for center personnel to control the nature of the data that is available to non-traffic operations centers and the media.
- The center shall distribute traffic data to the media; the capability to provide the information in both data stream and graphical display shall be supported.
- The center shall distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.
- The center shall retrieve locally stored traffic information, including current and forecasted traffic information, road and weather conditions, traffic incident information, information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements), and the definition of the road network itself.
- The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
- The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
- The center shall remotely control driver information systems that communicate directly from a center to the vehicle radio (such as Highway Advisory Radios) for dissemination of traffic and other information to drivers.
- The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
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 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.
