FIELD: transport engineering.
SUBSTANCE: proposed device contains units of pairs of friction or sliding shoes moving on metal guide rail, each being attached to self-guided device by rollers running along said guide rail. Shoes from electric circuit with guide rail including detector with safety circuit energized by low-voltage generator circuit with terminals BT+ and BT- through which current passes through shoes and guide rails at reliable grounding contacts. Depending on quality of electric contact on shoes, safety circuit will be either opened or closed, thus showing presence or absence of potential risk. Proposed invention is designed for manufactures of public vehicles running on tires and being self-guided.
EFFECT: improved safety of passengers inside and outlet the vehicle.
