National ITS Architecture Functional Requirements
associated with City of Charlottesville TMC:

Collect Traffic Surveillance
  1. The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
  2. The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
  3. The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.
  4. The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
  5. The center shall maintain a database of surveillance and sensors and the freeways, surface street and rural roadways, e.g. where they are located, to which part(s) of the network their data applies, the type of data, and the ownership of each link (that is, the agency or entity responsible for collecting and storing surveillance of the link) in the network.
  6. 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 data.
TMC Signal Control
  1. The center shall remotely control traffic signal controllers.
  2. The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
  3. The center shall collect traffic signal controller fault data from the field.
  4. 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.
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 collect operational status for the driver information systems equipment (DMS, HAR, etc.).
  3. The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
  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 distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.
  6. 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.
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 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 receive inputs concerning upcoming events that would effect the traffic network from event promoters, traveler information service providers, border crossings, and intermodal freight depots.
  3. 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.
  4. The center shall provide road network conditions and traffic images to emergency management centers to support the detection, verification, and classification of incidents.
  5. The center shall provide video and traffic sensor control commands to the field equipment to detect and verify incidents.
TMC Incident Dispatch Coordination/Communication
  1. 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.
  2. The center shall coordinate planning for incidents with emergency management centers - including pre-planning activities for disaster response, evacuation, and recovery operations.
  3. 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.
  4. 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.
  5. 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.
  6. The center shall provide road network conditions and traffic images to emergency management centers, maintenance and construction centers, and traveler information service providers.
  7. 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.
  8. The center shall coordinate information and controls with other traffic management centers.
  9. 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 Evacuation Support
  1. 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.
  2. 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.
  3. The center shall coordinate information and controls with other traffic management centers.
  4. 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.
Traffic Maintenance
  1. The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
  2. The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
