Patent ID: 8392100

Claim:
Method for determining traffic data, comprising the steps of: receiving, by a processor, statistical data relating to traffic at links of a street map, wherein the statistical data comprise travel speed data that are statistically obtained for each link; receiving, by the processor, condition data relating to the links of the street map, wherein the condition data comprise speed trap data and for at least one of the links: determining, by the processor, for which portions of the link the speed trap data are available; for each portion of the link, determining, by the processor, a first modification coefficient for modifying the travel speed data if the speed trap data are available, and determining, by the processor, a second modification coefficient for modifying the travel speed data if the speed trap data are not available; and determining, by the processor, the traffic data based on the travel speed data, the first modification coefficient for portions where the speed trap data are available, and the second modification coefficient for portions where the speed trap data are not available.
