Abstract: A navigation system and method for resolving discrepancies between a reported position and route data is presented. Based on a reported position, the navigation system identifies prospective road segments within a radius of the reported position. For each road segment, the navigation system generates a series of scores according to various attributes, including the current heading, current speed, proximity of reported location to the prospective road, and the like. Historical scores are also generated based on historical information, i.e., previous navigation device locations. Scores are normalized such that they can be compared, and optionally weighted according to particular implementation details. After scores have been generated for each prospective road, the prospective road, and its determined location, with the best score is selected as the resolved, actual location.
