    摘要: A method of processing data relating to an electronic map, the map comprising a plurality of segments representing navigable segments in the area covered by the map, the method comprising using a processing apparatus to generate segment data and comprising the steps of: collecting historic travel data for the segment; defining a jam condition for the segment, such that where the jam condition is satisfied the segment is classified as jammed and otherwise as not jammed; generating a jam probability for the segment according to the historic travel data and the jam condition definition; generating a jam speed for the segment using the historic travel data, the jam speed being indicative of the speed on the segment when the segment is considered jammed; and associating the jam probability and the jam speed with the segment in the electronic map.

    摘要: A method of generating expected average speeds of travel across one or more segments in the area covered by an electronic map, each segment representing a navigable segment in the area covered by the map and having associated therewith: an average speed of travel across that segment; segment data comprising at least one jam probability, the jam probability indicating the likelihood of a jam on that segment; and a jam speed indicative of the speed of travel on that segment when it is considered jammed. The method comprises using the segment data to predict whether a jam condition exists on at least one or each of the segments; and outputting the expected average speed of travel across these segments as: a) a first speed, where a jam condition is predicted to exist, the first speed being the jam speed for the relevant segment or a speed based thereon, or b) a second speed, where a jam condition is not predicted, the second speed being the average speed for the relevant segment or a speed based thereon.

    摘要: 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.
