The present invention relates to a vehicle driving speed display system. The vehicle driving speed display system includes: a driving speed sensing device installed on a specific position in a tunnel, and sensing the driving speed of a vehicle driving in a longitudinal direction of the tunnel; a speed section determination device storing display colors of a plurality of LED floodlights disposed in the tunnel in accordance with a plurality of vehicle speed sections, determining a corresponding vehicle speed section according to the driving speed of the vehicle sensed by the driving speed sensing device among the plurality of vehicle speed sections, and determining a display color of an LED floodlight in accordance with the corresponding vehicle speed section; and a driving speed display device installed at the entrance of the tunnel, and receiving the driving speed of the vehicle and the display color of the LED floodlight from the speed section determination device, thereby displaying the driving speed of the vehicle and the display color of the corresponding LED floodlight such that the driver of the vehicle entering the tunnel can check the driving status of the vehicle in the tunnel. Therefore, the present invention is capable of helping the driver to carefully drive the vehicle in the tunnel in preparation for an accident.
본 발명은 차량 주행속도 디스플레이 시스템에 관한 것으로, 터널 내의 특정 위치에 설치되고, 터널의 길이방향으로 주행 중인 차량의 주행속도를 감지하는 주행속도 감지장치; 복수의 차량속도구간에 따른 터널 내에 배치된 복수의 엘이디 투광등의 표시색상을 저장하고, 상기 복수의 차량속도구간 중에서 상기 주행속도 감지장치가 감지한 차량의 주행속도에 따른 해당 차량속도구간을 판단하고, 해당 차량속도구간에 따른 상기 엘이디 투광등의 표시색상을 판단하는 속도구간 판단장치; 및 터널 입구에 설치되고, 상기 속도구간 판단장치로부터 차량의 주행속도와 상기 엘이디 투광등의 표시색상을 수신하여, 터널 내로 진입하는 차량에서 운전자가 터널 내의 차량의 주행상황을 확인할 수 있도록 상기 차량의 주행속도와 상기 해당 엘이디 투광등의 표시색상이 디스플레이되도록 하는 주행속도 디스플레이 장치를 포함한다.
