摘要

The method involves differentiating two traffic jam conditions on basis of a measured speed. A traffic jam condition is recognized, if the measured speed is smaller or equal to a preset speed during a preset time interval that is longer or equal to another preset time interval. Another traffic jam condition is recognized, if the former condition is not recognized, and the measured speed is smaller or equal to another preset speed during the preset time interval that is longer or equal to another preset time interval for recognition of the former jam condition.
