METHODS AND APPARATUS FOR ROUTE COMPARISON
First Claim
1. A computer implemented method of route comparison, comprising:
- receiving, by the computer, data indicative of first and second routes between a start location and a destination location wherein the first and second routes are generated using digital map data;
determining, by the computer, nodes of the first and second routes having a minimum coupling distance, wherein the minimum coupling distance is determined based upon nodes of the first and second routes constrained to within a predetermined distance of a current node of each route; and
determining, by the computer, a similarity index for the first and second routes based upon the minimum coupling distance and a threshold coupling distance.
