The present invention relates to an emergency vehicle priority signal control system which provides a priority signal only to authorized vehicles and authorized persons by performing a verification process using a password and management information in a PPC board, thereby effectively preventing use of the vehicle terminal due to theft and duplication. The present invention can minimize damage to a general vehicle. In addition, the PPC board for judging whether the priority signal is provided to an emergency vehicle can be interlocked with an existing roadside base station and, at the same time, can be mounted inside a traffic signal controller previously installed in the form of an option board, thereby making installation, replacement and inspection simple, as well as preserving city appearances. In addition, the manufacturing cost can be reduced. The emergency vehicle priority signal control system of the present invention comprises: an in-vehicle terminal installed in the emergency vehicle, for receiving and storing a password from a user when the power is turned on, and for sending out access request data including current location information via GPS and the password; a roadside base station installed on a road and receiving the access request data from an adjacent vehicle terminal; a traffic signal controller for managing and controlling a present system of assigned traffic lights; and a PPC board. The PPC board receives the access request data from the roadside base station, verifies whether the access request data is normal data by comparing the password of the access request data with the previously stored password, and uses the location information of the access request data periodically received when the access request data is normal data in order to request the priority signal together with traveling direction information of the emergency vehicle to the traffic signal controller when the location of the emergency vehicle enters a setting area (S) set for each predetermined moving direction.

    본 발명은 PPC 보드에서 비밀번호 및 관리정보를 이용한 검증과정을 수행함으로써 인가된 차량 및 인가자에 한해서만 우선신호를 제공하여 도난 및 복제 등으로 인한 차량단말기의 사용을 효율적으로 방지할 수 있으며, 일반 차량의 불필요한 피해를 최소화할 수 있고, 긴급차량에게 우선신호 제공 여부를 판단하는 PPC 보드가 기 설치된 노변기지국에 연동 가능함과 동시에 옵션 보드 형태로 기 설치된 교통신호 제어기 내부에 장착되도록 구성됨으로써 설치, 교체 및 점검이 간단함과 동시에 도시미관을 해치지 않으며, 제조비용을 절감시킬 수 있는 긴급차량 우선신호 제어시스템에 관한 것이다.
