摘要： A method of providing a graphical indication of traffic congestion along a stretch of physical road notionally divided by a traffic information provider into one or more road segments is disclosed. The invention also covers a navigation system, portable navigation device, and or software capable of implementing such a method. The method is characterized by the steps of (i) determining that stop-start type traffic congestion exists by analyzing the traffic information received for each of a plurality of adjacent or proximate road segments and identifying that different traffic congestion severities prevail therein, (ii) determining an aggregated traffic congestion value for some or all of said plurality of segments and comparing that value to a first threshold value, a positive comparison result therewith being indicative of a level of congestion for said segments which should be identified to a user graphically, (iii) determining a measure of the relative density of segments within said plurality of segments for which the aggregated traffic congestion value does not result in a positive comparison, and (iv) displaying one of a plurality of different graphical indicators repeatedly for all said plurality of segments, the particular graphical indicator being dependent on said determination, and thus providing an indication of both the relative overall severity of traffic congestion in said plurality of segments, and that a stop-start type of traffic congestion prevails along the stretch of road comprised of said plurality of segments.

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 is provided of providing jam warning messages in relation to jams affecting navigable segments of a network of navigable segments. The method comprises, for each of one or more identified jams, obtaining a jam tail flow speed for the jam. The jam tail flow speed is preferably determined from the analysis of positional data relating to the current or relatively recent movement of a plurality of devices associated with vehicles along at least some navigable segments of a navigable network with respect to time. The jam tail flow speed is used to generate, or to determine whether to generate, a jam warning message in respect of the jam.
