MEASUREMENT METHOD FOR PROVING STATE OF VEHICLE HOLDING INSUFFICIENT FOLLOWING DISTANCE

PROBLEM TO BE SOLVED: To provide a method for identifying a violation vehicle without holding sufficient vehicle following distance by a simple operation from a police car under high speed travel and for enhancing its admissibility. SOLUTION: The police car A on which a violation evidence creating device in which a laser distance measuring function and a photographic image acquiring function are incorporated is mounted irradiates a laser beam on a rear part of a forward vehicle C obliquely from behind a suspected vehicle B without having the vehicle following distance by using a laser distance measuring device, measures a distance, simultaneously takes its state photograph with an electronically interlocked CCD camera and defines it as an evidence photograph. Three vehicles as a front part of the police car A, the suspected vehicle B without holding the vehicle following distance and the front vehicle C are portrayed in one photograph, positional relation among the three vehicles is clearly read and a fact that the police car is not in front of the suspected vehicle is proved. Namely, a measurement value N is larger than the vehicle following distance L between the front part of the suspected vehicle and the rear part of the front vehicle and, when the measurement value N is shorter than violation distance, L is also violated.
