Traffic light management system and traffic light management method

A traffic light management system that manages display of traffic lights includes a communication device, a control device, and a map database. The control device performs emergency control of the display when abnormal traveling information indicating the information on an abnormally traveling vehicle is included in the information received from a communication vehicle. In the emergency control, the control device predicts a future trajectory of the abnormally traveling vehicle based on the abnormal traveling information. Next, the control device generates the emergency control signal for temporarily prohibiting passage at an intersection and a crosswalk on a road along the future trajectory based on the map information and the future trajectory. After that, the control device sends the emergency control signal to controlled traffic lights. The controlled traffic lights are each a traffic light at the intersection and the crosswalk on a road along the future trajectory.

RAPID DEPLOYMENT OPERATOR CONTROLLED PORTABLE EMERGENCY TRAFFIC CONTROL SYSTEM
20220406177 · 2022-12-22 ·

A user-controlled portable traffic control system comprises one or more traffic signal units and a wireless handheld remote-control unit. Each traffic signal unit provides instruction to approaching motorists via a segmented backlit display consisting of first and second message panels. The wireless handheld remote-control unit allows a user to communicate commands to the traffic signal units via a transceiver circuit. Additionally, the handheld remote-control unit includes an interface indicating system status information via a plurality of indicator lights corresponding to the traffic signal units.
