摘要： The invention provides a method of resolving a location from an ordered list of location reference points being representative of nodes in an encoder digital map and each having attributes representative of a specific line or segment in said encoder digital map emanating from or incident at those nodes. The method comprises the steps of (i) for each location reference point, identifying at least one candidate node existing in a second digital map, and, using the available attributes of that location reference point, identifying at least one candidate line or segment existing in said second digital map emanating from or incident at said candidate node, (ii) performing a route search within said second digital map between: (a) at least one of said at least one candidate node and the corresponding candidate line or segment emanating therefrom or incident thereat, and (b) at least one of a candidate node for the next location reference point appearing in the list and the corresponding candidate line or segment emanating therefrom or incident thereat, and extracting from said second digital map each line or segment forming part of the route so determined between said candidate nodes, (iii) repeating step (ii) for each consecutive pair of location reference points up to and including the final location reference point appearing in the list. Preferably, the route search is a shortest path route search, most preferably operating on respective pairs of successive candidate nodes, and includes a means of ensuring that the corresponding line or segment of the first of the pair of nodes forms part of the route resulting therefrom.

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 efficient method of encoding a continuous path within a road network is described. Ideally the path to be encoded is capable of being completely represented within a digital map and expressible as a path list of lines and/or segments existing in said digital map and consecutively ordered. The method comprises the steps of: (i) storing a start position in a route search list, said start position being one of: (a) the line or segment first appearing in said path list or, where the start node of said first line or segment is artificial, the first line or segment appearing in said digital map having a real start node and which leads directly to said first line or segment optionally through other artificial nodes, or (b) a most recently identified deviation line or segment also appearing in said path list; (ii) determining a path from the start node of the start position and including said start position to an end node of the last line or segment in the path list within said digital map, said path being determined according to an algorithm, (iii) comparing the shortest path so determined to the path list for identity, and in the absence of identity, identifying at least one deviation line or segment being part of the path list and having a start node representative of an intersection in said digital map but not being the line or segment first appearing in said path list, and if such deviation line or segment does not terminate at the end node of the last line or segment appearing in the path list, repeating step (i) using said deviation line or segment, and (iv) Storing the last line or segment in the path list in said route search list if not already stored. Most preferably, the algorithm used is a shortest path algorithm.
