The invention relates to a method and a stationary device for communication on the basis of an ad-hoc interacting motor vehicle communication system, particularly of the wireless variety. Communication occurs between the road users and/or pedestrians themselves and/or between road users and/or pedestrians and the traffic infrastructure wherein, in the near field of a traffic route junction, particularly T-junctions or intersections of traffic routes such as road or railway junctions, a radio transmission/receiving device associated with a first road user continuously transmits a message to at least one second radio transmission/receiving device that is associated with a device of the traffic infrastructure and located in the radio coverage range of said first radio transmission/receiving device, the message being transmitted such that a first direction of a change in position of the first road user is detected on the basis of the received message, a history of detected directions is compiled on the basis of these messages, a first correlation is determined between said first direction and the historical directions, a second correlation is determined with the result of said first correlation and a reference traffic lane of pre-plotted traffic lanes at the traffic route junction, said reference traffic lane corresponding to the geographic course and being the basis for road user and/or pedestrian control, particularly when initialising the traffic control, and road users and/or pedestrians being controlled on the basis of said first and/or second correlation.

The invention relates to a method for communication on the basis of an, in particular wireless, motor vehicle communication system interacting in an ad-hoc manner, wherein the communication takes place between road users themselves and/or between road users and traffic infrastructure, in which, in the vicinity of a node for traffic routes, particularly junctions or intersections between traffic routes such as road or rail junctions, a radio transmission/radio reception device associated with a first road user continuously sends a message to at least one second radio transmission/radio reception device, which is situated in the radio coverage area of the first radio transmission/radio reception device and is associated with a device for the traffic infrastructure, the message is sent such that, on the basis of the received message, for each manoeuvre that is possible at the node, at least one value correlating to a probability of execution of the manoeuvre at the node is ascertained, and the road users are controlled on the basis of the correlating value. The invention also relates to a device for the traffic infrastructure and to a road user device having means for carrying out the method.
