FIELD: transport.
SUBSTANCE: in compliance with this method, green light is switched on with time delay relative to red light switching on. Prior to switching of green light, radar detects vehicles moving to junction from its both sides. Spatial and time coordinates of detected vehicles are periodically measured with the help of said radar. Data on quantity and spatial and time coordinates of detected vehicles are transmitted to controller. The latter computes the braking distance and stoppage time before stoppage nearby stop-line and completion of crossing of junction and turns to other road. Controller is switches on the light green signal with variable time delay after registration of vehicle stoppage nearby stop-line, termination of junction crossing and turn to other road.
EFFECT: decreased quantity of accidents at signal-controlled junctions.
