METHOD AND APPARATUS FOR WARNING OTHER ROAD USERS WHEN A VEHICLE IS TRAVELLING THE WRONG WAY ON A MOTORWAY OR DUAL CARRIAGEWAY

摘要

The invention relates to a method (300) for warning (310) other road users (204) when a vehicle (102) is travelling the wrong way on a motorway or dual carriageway, wherein the method (300) has a step (301) of preliminary detection, a step (306) of set-up, a step (304) of detection and a step (310) of provision. In step (301) of preliminary detection, a wrong-way travel potential for possible wrong-way travel by the vehicle (102) is detected in a preliminary fashion. In step (306) of set-up, a communication link (200) to at least one road user (204) that is at risk from the wrong-way travel is set up if the wrong-way travel potential is greater than a preliminary warning value. In step (304) of detection, the wrong-way travel by the vehicle (102) is detected. In step (310) of provision, a piece of wrong-way driver information is provided for the road users (204) at risk via the communication link (200) that has been set up if the possible wrong-way travel is detected as actual wrong-way travel.
