Abstract

PURPOSE:To provide a safety system for preventing occurrence of an accident of vehicle at a curved road, which comprises means for receiving, from means disposed by the side of the road at the inlet portion of a curve of the road, information relating to the allowable vehicle speed when travelling along the curve, and means for producing an alarm of overspeed if the actual travelling speed of the vehicle is higher than the allowavble speed. CONSTITUTION:When a vehicle 3 comes near the inlet of a curve of road and approaches transmitter 1 disposed by the side of the road, electric waves containing information relating to distance Dm of the curve and reference allowable speed Vm for the curve, transmitted from transmitter 1, is received from antenna 11a to receiver 11 on the vehicle 3, whereupon reception starting signal is supplied to micro-computor 15 and it starts operational processing of safety control programme. That is, actual travelling speed of the vehicle is detected from the output from vehicle-speed sensor 12, and it is compared with the safety speed range determined by the allowable speed. Here, if the actual vehicle speed is higher than the safety speed range, alarm buzzer 16 is actuated.
