A method for detecting the direction of travel of and for determining travel in the wrong direction by a vehicle which is moving on a lane in a section of road. Identifiers are respectively emitted by an arrangement of radio beacons which are arranged along the lane. When the vehicle travels through the section of road, a radio receiver, in particular a cell phone device, which is arranged in the vehicle, successively receives the emitted identifiers of the radio beacons. The actual direction of travel of the vehicle is determined on the basis of the sequence of the successively received identifiers.
