- 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 provide road network conditions and traffic images to emergency management centers, maintenance and construction centers, and traveler information service providers.
- The center shall exchange road network status assessment information with emergency management and maintenance centers including an assessment of damage sustained by the road network including location and extent of the damage, estimate of remaining capacity, required closures, alternate routes, necessary restrictions, and time frame for repair and recovery.
- The center shall receive inputs from emergency management and transit management centers to develop an overall status of the transportation system including emergency transit schedules in effect and current status and condition of the transportation infrastructure.
- 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 incident management.
TMC Signal Control
- The center shall accept notifications of right-of-way requests from pedestrians.
- The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
- The center shall collect traffic signal controller fault data from the field.
- The center shall implement control plans to coordinate signalized intersections, under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, emergency vehicle preemptions, the passage of commercial vehicles with unusual loads, equipment faults, pedestrian crossings, etc.
- The center shall remotely control traffic signal controllers.
Traffic 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.
- 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) fault data send to the maintenance center for repair.
- 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 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.
TMC Work Zone Traffic Management
- The center shall collect operational status for the driver information systems equipment in work zones.
- The center shall collect fault data for the driver information systems equipment in work zones for repair.
- The center shall receive proposed maintenance and construction work plans, analyze the activity as a possible incident, and provide work plan feedback to the sending center.
- The center shall receive work zone images from a maintenance center.
- The center shall analyze work zone images for indications of a possible incident.
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 execution of evacuation strategies with emergency management centers - including activities such as setting closures and detours, establishing routes, updating areas to be evacuated, timing the process, etc.
TMC Transportation Operations Data Collection
- The center shall collect real-time information on the state of the regional transportation system including current traffic and road conditions, weather conditions, special event and incident information.
