Claim Text:
1. Method for obtaining emission and/or fuel consumption data associated with a road segment, the method comprising the steps of receiving by a system comprising a receiving facility at least position data from a vehicle, determine a respective value for at least a first and a second parameter indicative for a movement of the vehicle, the first and the second parameter including at least a speed and an acceleration, storing a frequency distribution having classes for respective combinations of value ranges for the first and the second parameter, updating a frequency count for a class of said frequency distribution corresponding to the determined values for the first and the second parameter, repeating the previous steps, therewith calculating an associated relative frequency for each class, the associated relative frequency for each class being the relative frequency with which a combination of respective values for the first and the second parameters was determined within the respective value ranges for each class, calculating an expected emission and/or fuel consumption for a typical vehicle on said road segment on the basis of an emission or fuel consumption model specifying an expected emission or expected fuel consumption associated with each class, wherein the expected emission or expected fuel consumption associated with each class is weighted with its associated relative frequency.
