Collect Traffic Surveillance
- 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.
- 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 )
- The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
- 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 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 distribute traffic images from CCTV systems 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.
Field Management Stations Operation
- The filed management station shall pass data provided by the center to local field devices and report data from the field devices back to the center.
- The field management station shall accept configuration information from the center.
Roadway Basic Surveillance
- The field element shall return sensor and CCTV system fault data to the controlling center for repair.
- The field element shall return sensor and CCTV system operational status to the controlling center.
- 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.
Roadway Signal Controls
- The field element shall return traffic signal controller fault data to the center.
- The field element shall return traffic signal controller operational status to the center.
- The field element shall report current preemption status to the center.
- The field element shall report the current signal control information to the center.
- The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
- The field element shall respond to pedestrian crossing requests by accommodating the pedestrian crossing.
- The field element shall control traffic signals under center control.
- The field element shall report current transit priority status to the center.
TMC Signal Control
- The center shall remotely control traffic signal controllers.
- The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
- The center shall manage boundaries of the control sections used within the signal system.
- The center shall implement control plans to coordinate signalized intersections based on data from sensors.
- 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.
- 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 accept notifications of pedestrian calls.
Traffic Equipment Maintenance
- 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.
- 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 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 collect and store CCTV surveillance system (traffic, pedestrian) fault data send to the maintenance center for repair.
- 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) operational status.
- The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
