A method is provided for generating traffic information for at least one vehicle, the information including at least one position. The method includes the following acts: comparing a currently used position table to at least one further position table; determining deviations in entries in the position tables; and, if a deviation is present, using the position of the deviating entry in one of the position tables as a reference point for the traffic information to be generated. A system for generating traffic information is described.

Method and system for generating traffic information for at least one vehicle

To ascertain traffic status data, a speed of a vehicle is acquired multiple times at predefined time intervals. The respective acquired speed is assigned to a first speed range when the respective acquired speed of the vehicle is greater than at least one predefined speed threshold. Furthermore, a first count is increased when the respective acquired speed is assigned to the first speed range. The respective acquired speed is assigned to a second speed range when the respective acquired speed of the vehicle is less than the at least one speed threshold, and a second count is increased when the respective acquired speed is assigned to the second speed range, wherein a holding phase is recognized while the respective acquired speed has a speed value in a predefined range around the value zero once or multiple times in succession. During the recognized holding phase, the acquired speeds having the speed value in the predefined range around the value zero are not taken into consideration for a predefined non-consideration number of speed acquisition periods with respect to the adaptation of the second count.

Method and apparatus for determining traffic status

A method is provided for determining an ecological route attribute, in which at least one current energy consumption value is determined by a motor vehicle. A current measurement location is determined by the motor vehicle. An ecological location attribute, which includes the measurement location and the current energy consumption value, is formed by the motor vehicle and transmitted to a central processor. An ecological route attribute is determined by the central processor on the basis of a plurality of received ecological location attributes, which in each case includes a measurement location, which ecological route attribute describes an energy consumption on a route section which has a prescribed spatial relationship with the measurement locations.
