The present invention relates to a traffic light, and more particularly, to an emergency traffic light device for securing an emergency lane to enable the rapid running of emergency vehicles and smooth communication of general vehicles.

In recent years, various disaster prevention systems have been introduced, such as automatic security systems for protecting personal property and human life, and automatic monitoring systems for monitoring disasters such as fire or gas leakage. For example, an automatic monitoring system is installed in a specific building to detect fires, gas leaks, and the like, a transmitter for receiving operation information of the sensors, a plurality of transmitters installed in a certain area, and wired / wireless. Includes disaster prevention centers connected via a network. The disaster prevention center contacts, for example, a public office such as a fire station, a police station, a hospital, or the like when a fire occurs in a specific building. The government office contacted the emergency vehicle, such as fire trucks, police cars, emergency vehicles to go to the fire notification site to extinguish the fire, take the patient to the hospital and determine the cause of the fire.

However, in the past, no traffic control or road traffic regulations and related facilities are provided for the rapid driving of emergency vehicles when dispatching emergency vehicles. However, there is only an tacit provision that a general vehicle on the road must yield a lane when an emergency vehicle is found or recognized at a short distance. Accordingly, the general vehicle in driving has to change lanes for rapid driving of emergency vehicles, but it is difficult to change lanes on a road with heavy traffic. In this case, the emergency vehicle must slow down, especially at a congestion road or at a traffic intersection, waiting for the road to communicate. As a result, the dispatch time of emergency vehicles can only be delayed. On the contrary, the damages to property and lives of fire reporting sites increase. On the other hand, when an emergency vehicle runs in disregard of a traffic signal, a traffic jam and a traffic accident often occur.
