| Functional Requirements: |
Collect Traffic Surveillance
- The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
- The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.
- The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
- 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.
- 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.
HRI Traffic Management
- The center shall remotely control highway-rail intersection (HRI) equipment located in the field.
- The center shall accept collect highway-rail intersection (HRI) advisory or alert data from rail operations centers.
- The center shall collect highway-rail intersection (HRI) equipment operational status and compare against the control information sent by the center.
- The center shall provide the highway-rail intersection (HRI) equipment operational status to rail operations centers.
- The center shall collect incident information related to a highway-rail intersection (HRI), such as intersection blockages or crashes or equipment malfunctions.
- The center shall implement control plans to coordinate signalized intersections around highway-rail intersections (HRI), under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, equipment faults, pedestrian crossings, etc.
TMC Incident Detection
- 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.
- 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 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 coordinate information and controls with other traffic management centers.
- 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 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 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 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 sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.
- The center shall collect environmental sensor operational status.
- The center shall collect environmental sensor equipment fault data and 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 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.
