Functional Areas

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 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 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.
