The present invention discloses a road projecting method and system for a traffic light. A passable region and an impassable region are determined according to a current state and a time period of the traffic light and a preset travelling speed of a vehicle; on a map, the passable region is displayed in a first manner, and the impassable region is displayed in a second manner; and the first manner is different from the second manner. The road projecting method and system for a traffic light provided by the present invention divides the road on which the vehicle is running into the passable region and the impassable region on the map, and the passable region and the impassable region are displayed in different manners; therefore, when a driver is farther from the traffic light, the driver can know in advance the state of the traffic light when the vehicle runs to the intersection, thereby avoiding congestion caused by stop of a large number of vehicles close to the intersection and improving the traffic efficiency.
