Abstract
Methods, systems and computer program products providing traffic light status notifications to drivers are provided. Aspects include determining that a first vehicle, operated by the driver, is approaching a traffic light and receiving, by the first vehicle, traffic light status data from one or more second vehicles in a vicinity of the traffic light via vehicle-to-vehicle communication. Aspects also include obtaining a traffic light pattern for the traffic light from a traffic light pattern database and determining a predicted status of the traffic light at a time when the first vehicle will reach the traffic light based on a speed of the first vehicle, the traffic light status data, and the traffic light pattern. Aspects further include notifying the driver of the predicted status of the traffic light.
