A method for determining road traffic characteristics utilizing movement data of vehicles which have communication devices trackable by radio positioning. The data includes time and place data regarding acceleration and braking maneuvers recorded by the communication devices. Chronological progression of acceleration and braking maneuvers is evaluated with respect to the occurrence of a predetermined characteristic pattern for a specific traffic characteristic. When such a pattern is detected and is linked to the location at which the maneuvers took place, this location is determined to be the location of the traffic characteristic. A report regarding the characteristic and its location is submitted to a central data collection point. In the central data collection point, the reports are evaluated. When a threshold number of similar reports from various users regarding the traffic characteristic at a certain location is exceeded, then this characteristic is classified as being reliably determined at the corresponding location. |
