Abstract (en)
[origin: WO2005064565A1] The invention particularly relates to a method for provision of traffic status information, in the context of traffic status recognition (500), by means of a motor vehicle, in particular, traffic information for traffic positional detection, preferably, traffic information for detection of congestion, whereby the vehicle comprises a device for position recognition using a digital road map stored on a data support, in particular, a GPS navigation system with a DVD as digital road map. According to the invention, qualitatively high-grade traffic information may be provided at reasonable cost, whereby, in a first step, a determination of whether the vehicle is located closer to a road junction than a pre-determined distance (S3) is carried out, optionally, in a second step, a determination is carried out as to whether speed is less than a pre-determined speed (S1) and, optionally, in a third step largely for the traffic status recognition, the average speed of the vehicle, during a period (v(t-60)) leading up to the moment at which the vehicle reaches the junction area, is used.
