- The center shall provide road network conditions and traffic images to emergency management centers to support the detection, verification, and classification of incidents.
- The center shall provide video and traffic sensor control commands to the field equipment to detect and verify incidents.
TMC Incident Dispatch Coordination/Communication
- The center shall coordinate planning for incidents with emergency management centers - including pre-planning activities for disaster response, evacuation, and recovery operations.
- The center shall exchange incident information with emergency management centers, maintenance and construction centers, transit centers, information service providers, and the media including description, location, traffic impact, status, expected duration, and response information.
- The center shall share resources with allied agency centers to implement special traffic control measures, assist in clean up, verify an incident, etc. This may also involve coordination with maintenance centers.
- The center shall receive inputs concerning upcoming events that would effect the traffic network from event promoters, traveler information service providers, media, border crossings, and rail operations centers.
TMC Regional Traffic Management
- The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
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 collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
- 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.
Traffic Equipment Maintenance
- The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
- The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.
TMC Evacuation Support
- The center shall coordinate planning for evacuation with emergency management centers - including pre-planning activities such as establishing routes, areas to be evacuated, timing, etc.
- The center shall support requests from emergency management centers to preempt the current traffic control strategy, activate traffic control and closure systems such as gates and barriers, activate safeguard systems, or use driver information systems to support evacuation traffic control plans.
- The center shall coordinate information and controls with other traffic management centers.
