In one embodiment, a system receives vehicle information from one or more ADVs. The system determines a location and a heading of each ADV from the vehicle information of the ADV. For each of the ADVs, the system determines if the ADV is approaching a traffic light junction based on the location and the heading of the ADV. The system sends the vehicle information of the ADVs to a traffic light control system in response to determining the ADV is approaching the traffic light junction, where the vehicle information is used by the traffic light control system to direct a traffic flow at the traffic light junction, including adjusting a time duration of a light signal at one or more traffic lights disposed at the traffic light junction in advance of the ADVs arriving at the traffic light junction.
