Abstract
Vehicle navigation systems may calculate prospective routes from a user's current location but may not evaluate the potential benefit of turning around to a prior divergence point. A system can address this by storing data for an unchosen alternative path and its associated divergence point from a selected route. The system can monitor real-time conditions, such as traffic congestion, for both the active route and the stored alternative path. If a trigger condition is met, for example, a significant delay on the active route, a reversion calculation can be performed. This computation can determine an estimated time to backtrack to the divergence point and then proceed along the alternative path. The system may then present a comparison between an estimated time for continuing on the current route and an estimated time for the reversion scenario, providing a basis for a driver's decision.
