METHOD FOR DETERMINING THE LENGTH OF A VEHICLE WHILE MOVING AND APPARATUS FOR IMPLEMENTING SAME

摘要

P The method according to the invention consists in measuring the time taken by a fixed point of the vehicle to pass from a first location to a second one separated by a predetermined distance from the first, so as to determine the speed of the vehicle, passing this moving vehicle at said speed between a light source and a light detector, measuring the time taken by a vehicle to obstruct the reception by the detector of the light emitted by the light source and calculating at from these two time measurements the overall length of the vehicle. /P
