Method and Device for Communication Between Road Users and/or Pedestrians and a Traffic Infrastructure on the Basis of an Ad-Hoc Wireless Motor Vehicle Communications System for Traffic Control

摘要

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.

1. A method for communication on the basis of a, in particular wireless, motor vehicle communication system interacting in an ad-hoc manner, wherein the communication takes place among road users and/or between road users and traffic infrastructure, characterized in that
a) in the vicinity of a node of traffic routes, particularly T-junctions or intersections of traffic routes such as road junctions or grade crossings, 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, associated with a device of the traffic infrastructure, that is in a radio coverage area of the first radio transmission/radio reception device, b) the message is sent in a manner such that the received message is taken as a basis for ascertaining a first direction of a change of position of the first road user, c) the messages are taken as a basis for forming a history about ascertained directions, d) a first correlation between the first direction and the history of directions is ascertained, e) a second correlation with the result of the first correlation and a reference lane from predetermined lanes at the node of traffic routes is ascertained, said reference lane being taken as a basis for control of the road users and corresponding to the geographical profile, particularly for initialization of traffic control, f) the first correlation and/or second correlation is/are taken as a basis for controlling the road users.
