Beschreibung
Zusammenfassung:	A method of creating a speed estimation representative of vehicle speed along one or more road segments. In at least one embodiment, the method includes obtaining at least reference speed data from a reference source of data and second speed data from a second source of data, wherein the second source is different from the reference and the speed data is indicative of vehicle speed along the or each road segment; using the reference speed data to verify the second speed data and modifying the second speed data according to the verification; and generating an estimation of vehicle speed for the or each road segment based upon the verified second speed data.
