Abstract

The present disclosure provides a traffic light for cooperative vehicle-infrastructure and a method for controlling the same. The traffic light for cooperative vehicle-infrastructure includes: a communication module, a central processing module, a Global Positioning System GPS module and a scheduling module. The communication module is configured to receive a set of messages sent by vehicles periodically. The GPS module is configured to locate the position of the traffic light. The central processing module is configured to perform calculations and analyses on the received set of messages and the position of the traffic light, dynamically set lasting times of red and green lamps of the traffic light, and send a control signal carrying the set times to the scheduling module. The scheduling module is configured to control the lasting times of the red and green lamps of traffic light according to the control signal carrying the set times.
