Method for analyzing operation characteristics of a vehicle driver, wherein a driver operation characteristics parameter is determined by an analyzing vehicle system in the vehicle, the parameter is sent to a stationary processing unit, and the stationary processing unit determines a driver operation characteristics wherein the parameter is a plurality of position coordinates and speed data of the vehicle, the method being characterised in that: - the analysing vehicle system determines the travelling speed of the vehicle at a plurality of geographic locations, the vehicle system then separates such speed data from the location data where this speed was driven, the speed data are separated from the location data in different files containing either the location data or the respective speed data, the separation is done in a way that the direct correlation between speed data and corresponding location data is destroyed due to the separation, - at the analysing vehicle system, a plurality of speed data are integrated to an average speed over an area of interest, - at the analysing vehicle system, location data as position coordinates of the vehicle are stored as entries in a file and the sequence of entries of the file is randomized, and the randomly organized location data and the average speed over an area of interest are transmitted to the stationary processing unit for further processing, - at the stationary processing unit the randomly organized location data are processed via a data base that assigns to each coordinate point on a road a speed reference, wherein the stationary processing unit extracts from the data base the information how fast the vehicle was allowed to drive on the respective roads associated with these sets of GPS location coordinates, - these speed limits are then combined into an average speed reference for the area of interest, - the resulting average speed reference is then compared to the average actual speed of the vehicle contained in the respective area of interest, and the delta between the two average speed values defines a speed metric. - the analysing vehicle system determines the travelling speed of the vehicle at a plurality of geographic locations, the vehicle system then separates such speed data from the location data where this speed was driven, the speed data are separated from the location data in different files containing either the location data or the respective speed data, the separation is done in a way that the direct correlation between speed data and corresponding location data is destroyed due to the separation, - at the analysing vehicle system, a plurality of speed data are integrated to an average speed over an area of interest, - at the analysing vehicle system, location data as position coordinates of the vehicle are stored as entries in a file and the sequence of entries of the file is randomized, and the randomly organized location data and the average speed over an area of interest are transmitted to the stationary processing unit for further processing, - at the stationary processing unit the randomly organized location data are processed via a data base that assigns to each coordinate point on a road a speed reference, wherein the stationary processing unit extracts from the data base the information how fast the vehicle was allowed to drive on the respective roads associated with these sets of GPS location coordinates, - these speed limits are then combined into an average speed reference for the area of interest, - the resulting average speed reference is then compared to the average actual speed of the vehicle contained in the respective area of interest, and the delta between the two average speed values defines a speed metric.
