Functional Areas

Collect Traffic Surveillance

• 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 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.
• The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.

Roadway Basic Surveillance

• 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 CCTV system operational status to the controlling center.

Roadway Signal Controls

• The field element shall control traffic signals under center control.
• 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 return traffic signal controller operational status to the center.

TMC Signal Control

• The center shall accept notifications of pedestrian calls.
• 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 remotely control traffic signal controllers.

Traffic Equipment Maintenance

• 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.
