However, there is no effective solution to the case where fire / medical / police / military manpower and equipment transportation due to sudden fire or accident / accident is necessary. Especially in the case of fire trucks, ambulances, police cars, etc., it relies on the voluntary cooperation of general car drivers. In crowded urban areas, it is also impossible to get the chance of early resolution of incidents / accidents.

As one of the ways to solve this problem, there is a way to secure the course of the emergency vehicle by controlling the traffic light in the central control station. However, depending on the moving situation of the emergency vehicle, the central control station controls each traffic light individually, and it takes a lot of human and material costs especially in the city where incidents / incidents occur frequently. On the other hand, if the accuracy of the traffic signal control is lowered to reduce the cost, the traffic of the ordinary vehicle becomes unnecessary. Thus, there is a need for a signal control system that can be properly controlled in an emergency.
