Functional Areas

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 monitor, analyze, and distribute traffic images from CCTV systems 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 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.

Roadway Basic Surveillance

• The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.
• The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
• The field element shall return CCTV system operational status to the controlling center.
• The field element shall return CCTV system fault data to the controlling center for repair.
• The field element shall return sensor operational status to the controlling center.
• The field element shall return sensor fault data to the controlling center for repair.
• The field element shall return CCTV system fault data to the controlling center for repair.

Roadway Signal Controls

• The field element shall return traffic signal controller fault data to the maintenance center for repair.
• The field element shall control traffic signals at intersections and on main highways for urban and rural areas, under center control.
• The field element shall collect pedestrian images and pedestrian sensor data, and respond to pedestrian crossing requests via display, audio signal, or other manner.
• The field element shall provide the capability to notify the traffic management center that a pedestrian has requested right-of-way and when the request was or will be granted (request for right-of-way).
• The field element shall monitor operation of traffic signal controllers and report to the center any instances in which the indicator response does not match that expected from the indicator control information.
• The field element shall monitor operation of traffic signal controllers and report to the center any instances in which the indicator response does not match that expected from known indicator preemptions.
• The field element shall return traffic signal controller operational status to the controlling center.

Roadway Traffic Information Dissemination

• The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
• The field element shall include 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, under center control.
• The field element shall include pedestrian information systems under center control (e.g. warning pedestrians of a potential hazard, or providing mandatory instructions as to the availability of pedestrian access).
• The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
• The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.

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.

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 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.
• The center shall distribute traffic data to maintenance and construction centers, transit centers, emergency management centers, and traveler information providers.
• 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.
• 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 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 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.
