METHOD AND APPARATUS FOR DETERMINING TRAFFIC STATUS

摘要

In order to determine traffic status data, if it is detected that a vehicle is participating in a traffic flow, a speed of a vehicle is measured repeatedly at predefined time intervals. The respectively measured speed (vc) is assigned to a first speed range if the respectively measured speed (vc) of the vehicle is greater than at least one predefined speed threshold. Furthermore, a first counter reading (Z1) is increased if the respectively measured speed (vc) is assigned to the first speed range. If the respectively measured speed (vc) of the vehicle is less than the at least one speed threshold, the respectively measured speed (vc) is assigned to a second speed range and a second counter reading (Z2) is increased if the respectively measured speed (vc) is assigned to the second speed range. A holding phase (TvO) is detected while the respectively measured speed (vc) has a speed value in a predefined range around the value zero once or several times in sequence. During the detected holding phase (TvO), the measured speeds (vc) having the speed value in the predefined region around the value zero are not taken into account with respect to the adaptation of the second counter reading (Z2) for a predefined number of speed measurement periods to be disregarded.
