METHOD OF DETERMINING SURFACE TRANSPORT FACILITY SPEED Russian patent published in 2011 - IPC G01P3/50 

Abstract RU 2431847 C1

FIELD: physics.

SUBSTANCE: delay time is measured when signals reflected from road coat irregularities illuminated by transport facility mini lamps are received by light-sensitive elements. Note here that not all pulses from sensitive elements are estimated but solely separate particular pulses isolated in forecast time intervals by mechanical speed pickup.

EFFECT: higher accuracy.
