Patent ID: 8489354

Claim:
A method for verifying the speed of a vehicle having at least a front axle and a rear axle using sensors, the sensors being separated by a distance, the method including the following steps: (a) sensing a presence of the vehicle; (b) recording an image of the vehicle to enable the vehicle to be identified; (c) triggering the sensors to each emit a signal; (d) receiving the signals emitted by the sensors; (e) determining the speed of the vehicle; (f) determining a wheel base measurement for the vehicle; (g) identifying the vehicle from the recorded image of the vehicle; (h) comparing the determined wheel base measurement to a validated wheel base measurement of the vehicle being sensed; and (i) identifying a discrepancy between the determined wheel base measurement and the validated wheel base measurement of the vehicle being sensed as potential errors in the speed of the vehicle determined by step (e).
