FIELD: transport.
SUBSTANCE: invention relates to traffic safety devices to be used at railway crossing. Proposed device comprise hollow elements arranged at track-bed benches. Guard element is secured between said benches its ends being connected with inertial elements. Said elements are arranged under prop bases secured by rope to form block and tackle system. Proposed device is provide also with lock mechanisms connected by ropes with guard element and crossing guard control system. Said system consists of displacement transducers arranged at props and guard barriers and connected to processor input. Signal light is connected to processor second input while processor output is connected to lock mechanisms and drive.
EFFECT: higher traffic safety.
