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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of detecting the opening of closed roads","description":"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 r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9696169","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
