ABSTRACT:
A device for cracking down on disregard of a traffic signal includes a television camera for imaging a road, on which signal lights are mounted at a cross; a vehicle movement measuring instrument for processing image data coming from the television camera and measures traveling position and traveling speed of each vehicle; a signal state detector for detecting an indication color of the signal lights; and a traffic signal disregarding vehicle detector for detecting a vehicle which has disregarded a traffic signal, based on the traveling position and the traveling speed of the vehicle measured by the vehicle movement measuring instrument and the indication color of the signal lights detected by the signal state detector. The vehicle movement measuring instrument measures the distance from the cross and the speed of the vehicle. In the case where there is a vehicle traveling within the cross, while the signal state detector detects a red indication of the signal lights, it is detected as a vehicle which has disregarded the traffic signal, and a recorder records the traveling state and the registration number thereof.
