Functional Areas

Collect Traffic Surveillance

• 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 i
• The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
• The center shall monitor, analyze, and store multimodal crossing and high occupancy vehicle (HOV) lane sensor data under remote control of the center.
• 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 respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
• 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.

Roadway Basic Surveillance

• The field element shall collect, digitize, and send multimodal crossing and high occupancy vehicle (HOV) lane sensor data to the center for further analysis and storage.
• The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
• 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 return sensor and fault data to the controlling center for repair.
• The field element shall return sensor system operational status to the controlling center.

Roadway Data Collection

• The field element shall collect sensor status and sensor faults from roadside equipment and send it along with the recorded data to a center for archival.
• The field element shall collect traffic, road, and environmental conditions information.
• The field element shall include the sensors and supporting roadside devices that sense, collect, and send traffic, road, and environmental conditions information to a center for archival.

Roadway Signal Controls

• 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 control traffic signals at intersections and on main highways for urban and rural areas, under center control.
• 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 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 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 return traffic signal controller fault data to the maintenance center for repair.
• The field element shall return traffic signal controller operational status to the controlling center.

TMC Signal Control

• The center shall accept notifications of right-of-way requests from pedestrians.
• The center shall collect traffic signal controller fault data from the field.
• The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
• 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 commerc
• The center shall remotely control traffic signal controllers.

Traffic and Roadside Data Archival

• The center shall collect traffic sensor information from roadside devices.
• The center shall manage the collection of archive data directly from collection equipment located at the roadside.
• The center shall record the status about the imported traffic and roadside data.
• The center shall respond to requests from the Archive Data Administer to input the parameters that control the collection process.
• The center shall send the request for data and control parameters to the field equipment where the information is collected and returned.
• The center shall use the status information to adjust the collection of traffic and roadside data.

Traffic Maintenance

• The center shall collect and store CCTV surveillance system (traffic, pedestrian) fault data send to the maintenance center for repair.
• 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 sensor (traffic, pedestrian, multimodal crossing) operational status.
• The center shall collect environmental sensor equipment fault data and send to the maintenance center for repair.
• The center shall collect environmental sensor operational status.
• 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.
