Collect Traffic Surveillance
- 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 respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
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 Environmental Monitoring
- The field element shall include surface and sub-surface environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
- The field element's environmental sensors shall be remotely controlled by weather service providers such as the National Weather Service or value-added sector specific meteorological services.
- The field element shall provide weather and road surface condition data to centers.
Roadway Traffic Information Dissemination
- 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).
- The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
- The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.
TMC Environmental Monitoring
- The center shall remotely control environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
- The center shall remotely control environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
- The center shall assimilate current and forecast road conditions and surface weather information using a combination of weather service provider information (such as the National Weather Service and value-added sector specific meteorological services), data from roadway maintenance operations, and environmental data collected from sensors deployed on and about the roadway.
TMC Traffic Information Dissemination
- The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
- The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
- The center shall distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.
- 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.
