Methods and systems for providing advance warning of a change in status of a traffic light to drivers approaching an intersection. The systems and methods include secondary lights positioned in advance of a traffic light at an intersection so that they are visible to oncoming traffic; and using a controller to control the plurality of secondary lights to start flashing before the traffic light changes from green to yellow. Once activated, the lights flash in the direction of oncoming traffic to warn drivers approaching the intersection that a stop may be required and that caution should be exercised.

A method includes the step of receiving traffic signal display information from a traffic control unit controlling a display of a traffic signal located near an intersection when a vehicle is driving toward the intersection. The traffic signal display information includes a current display state of the traffic signal and information indicating a remaining time for which the current display state of the traffic signal will continues. The method further includes the step of acquiring traffic signal recognition information when the vehicle is driving toward the intersection. The traffic signal recognition information is recognized by a traffic signal detector mounted on the vehicle and indicating a current display of the traffic signal. The method further includes the step of controlling driving of the vehicle when the vehicle enters the intersection based on the traffic signal display information and the traffic signal recognition information.

Provided are a method and device for processing signal operation information of an intersection, and the method includes transmitting, to an external device, a driving status information message regarding a vehicle, determining a particular intersection, based on a current location and heading of the vehicle included in the driving status information message, and receiving, from the external device, a signal operation information message regarding the particular intersection, by using a geofencing area.
