associated with City of Charlottesville TMC:

TMC Incident Detection
  1. The center shall collect and store traffic flow and image data from the field equipment to detect and verify incidents.
  2. The center shall provide video and traffic sensor control commands to the field equipment to detect and verify incidents.
  3. The center shall provide road network conditions and traffic images to emergency management centers to support the detection, verification, and classification of incidents.
  4. The center shall receive inputs concerning upcoming events that would effect the traffic network from event promoters and traveler information service providers.
  5. The center shall exchange incident and threat information with emergency management centers as well as maintenance and construction centers; including notification of existence of incident and expected severity, location, time and nature of incident.
TMC Traffic Information Dissemination
  1. The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
  2. The center shall distribute traffic data to the media.
  3. The center shall distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, parking facilities, and traveler information providers.
  4. 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.
  5. The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
  6. The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
TMC Basic Surveillance
  1. The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
  2. The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.
  3. 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).
  4. The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
  5. The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
TMC Signal Control
  1. The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
  2. The center shall remotely control traffic signal controllers.
  3. The center shall collect traffic signal controller fault data from the field.
  4. The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
TMC Multi-Modal Coordination
  1. The center shall respond to requests from transit management centers for signal priority at one or more intersections along a particular transit route.
TMC Regional Traffic Management
  1. 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.
  2. 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 Evacuation Support
  1. The center shall coordinate evacuation information and controls with other traffic management centers.
  2. 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.
  3. 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.
  4. 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.
TMC Incident Dispatch Coordination
  1. The center shall coordinate information and controls with other traffic management centers.
  2. 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.
  3. The center shall provide road network conditions and traffic images to emergency management centers, maintenance and construction centers, and traveler information service providers.
  4. 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.
  5. 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.
  6. 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.
  7. The center shall coordinate planning for incidents with emergency management centers - including pre-planning activities for disaster response, evacuation, and recovery operations.
  8. 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.
