Abstract:
An apparatus measures and indicates the speeds of a vehicle at the beginning and end of braking of the vehicle by counting as many vehicle speed representative pulse signals as indicative of the speed per hour of the vehicle which are gated during the time that the desired number of clock pulses are counted in response to the beginning and end of braking of the vehicle, respectively.
