The present invention relates to a vehicle data detecting system improved in accuracy of detection. A pair of laser signal irradiates spaced apart from each other at a same width as a lane in the lengthwise direction and a plurality of pairs of the laser signal irradiate, thus an amount of data used for detecting the vehicle data and a sensing area is expanded in the widthwise direction of the lane, such that the accuracy and reliability of the detection is remarkably increased, installation, inspection, and maintenance and repair are simplified, and costs are reduced. A tolerance and a malfunction incurred upon the detection of the vehicle detection are accurately detected by using each of the vehicle speed and first thresholds (TH1) of the detected vehicle data, such that the accuracy and reliability of the detection is increased more, and civil complaint due to wrong data detection is remarkably reduced.
본 발명은 차선의 동일 폭으로, 길이방향으로 이격되게 출사되는 레이저신호들을 한 쌍으로 할 때 복수쌍의 레이저신호들을 출사함으로써 차량데이터 검출에 활용될 데이터양이 증가함과 동시에 감지영역이 차선 폭방향으로 확장되어 검출의 정확도 및 신뢰도를 현저히 높일 수 있으며, 설치, 점검 및 유지보수가 간단하며, 비용을 절감시킬 수 있고, 검출된 차량데이터들 각각의 차량속도 및 제1 설정값(TH1)을 이용하여 차량데이터 검출 시 발생한 오차 및 오동작을 정확하게 검출하도록 구성됨으로써 검출의 정확도 및 신뢰도를 더욱 높임과 동시에 잘못된 데이터검출로 인한 민원을 현저히 절감시킬 수 있는 차량데이터 검출 시스템에 관한 것이다.
