Patent number: 9696169Abstract: The described principles provide a method and system for identifying a potentially closed road based on reroute requests, and of accommodating the potential road closure while continuing to test the road status periodically via routing decisions and rerouting requests. While the optimal route assumes that the potentially closed road is open, a replacement route is defined assuming that the potentially closed road is closed. A fraction of users are sent along the optimal route, and if a reroute request is received, the potentially closed road is assumed to be closed still. The affected user is rerouted to a recovery route that matches the optimal route up to the potentially closed road, and then differs from the optimal route thereafter to avoid the potentially closed road.Type: GrantFiled: March 19, 2010Date of Patent: July 4, 2017Assignee: GENERAL MOTORS LLCInventors: Richard A. Johnson, Steven C. Tengler
