The invention relates in particular to a method for providing traffic condition data in the context of a traffic condition recognition (500) by a motor vehicle, in particular traffic condition data for detecting the position of traffic, preferably traffic condition data for detecting traffic jams. The aim of the invention is to provide high-quality traffic condition data at an acceptable cost. To achieve this, in a first step the type of road along which the vehicle is travelling is determined (202) by means of a position recognition device and a digital road map. In a second step, the category of road along which the vehicle is travelling is determined by means of the position recognition device and the digital road map (203). A third step utilises assignment means, in particular a table (204), which assigns at least one lower speed threshold (S1), one upper speed threshold (S2) and preferably also a normal speed to both the relevant road type and the relevant road category of the road along which the vehicle is travelling. Finally, in a fourth step, at least the lower speed threshold (S1) and the upper speed threshold (S2) are used, (optionally in modified form), to determine the traffic condition. |
