Abstract: A computer-implementable method for identifying the preferred route to be used, or ordering a set of routes to be used in order of preferability, for a given route requirement, in a computationally efficient manner is disclosed. The computer-implementable method selects a subset of stored routes having origins within a configurable radius of the required origin and destinations within a configurable radius of the required destination, calculates the distances between the two origins, between the two destinations, and between each origin and its corresponding destination, to compute various indicators of the similarity between the required route and each stored route in the subset. The computer-implementable method presents the selected stored routes ordered by a selected route-similarity indicator. The first such ordered selected stored route is the preferred route.
