Abstract
A method for geographic region detection of traffic infrastructure via a receiver disposed in the region of the traffic infrastructure for a detection region of the receive unit, wherein status data of vehicles is communicated by the vehicles several times to the receive unit via wireless communication during the period in which vehicles pass through the detection region of the receiver, the receiver, or a processor connected to the receive unit, computes a vector for each vehicle, where the vector extends from a first position of the vehicle to a second position of the vehicle, and the receiver or the processor determines directions of travel of the vehicles and the geographic location of roadways and/or lanes of the roadways of the traffic infrastructure in the detection region from the vectors of all the vehicles.
