TMC Incident Dispatch Coordination/Communication

• The center shall exchange alert information and status with emergency management centers. The information includes notification of a major emergency such as a natural or man-made disaster, civil emergency, or child abduction for distribution to the public. The information may include the alert originator, the nature of the emergency, the geographic area affected by the emergency, the effective time period, and information and instructions necessary for the public to respond to the alert. This may also identify specific information that should not be released to the public.
• 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 support requests from emergency management centers to remotely control sensor and surveillance equipment located in the field, provide special routing for emergency vehicles, and to provide responding emergency vehicles with signal preemption.
• 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.
• 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 coordinate information and controls with other traffic management centers.
• 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.

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.
• The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).

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.
• The center shall provide weather and road condition information to weather service providers and center personnel.
• The center shall respond to control data from center personnel regarding environmental sensor control and weather data collection and processing.

TMC Traffic Information Dissemination

• The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• 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 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 distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.
• 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.

Traffic Equipment Maintenance

• 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.
