Abstract

The invention relates to a device for measuring the speed of a vehicle (V) travelling on a road (CH), characterised in that it comprises a single image line sensor (C) positioned above the vehicle (V) and means (MOY) for estimating the speed of the vehicle from image lines (L1, L2) acquired by the sensor. The invention also relates to a method for measuring the speed of a vehicle travelling on a road from image lines acquired by the sensor of the device.
