Abstract
A method is disclosed for warning in case of wrong-way travel of a vehicle on a directional carriageway by means of an on-board unit carried by the vehicle, said on-board unit determining its position and direction of movement in a satellite-assisted manner, comparing the latter with a target direction of movement stored in a digital road map for this position and outputting a warning message when detecting a wrong-way travel, comprising: for a temporary change in course of a section of the directional carriageway, providing a radio beacon arranged upstream to said section and having a local radio coverage range; when the on-board unit enters the radio coverage range of the radio beacon, receiving a message sent by the radio beacon concerning the change in course in a transceiver of the on-board unit; and detecting the wrong-way travel depending on the received message.
