The traveled road is a road actually traveled by a vehicle. The extension road is a road continuous with the traveled road. The retrieval section includes a selection section. When multiple routes each to the destination are retrieved, the selection section selects a route from among the multiple routes based on a distance of an unrecognized road, a travel time taken to travel the unrecognized road, or a connection condition of the unrecognized road. The unrecognized road is a road other than the recognized road stored in the storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Navigation device and program for performing route guidance along a route using, as a recognized road, an extension road not actually traveled which extends straight from and is continuous with a road actually traveled","description":"A navigation device is provided, which includes a retrieval section that retrieves a route to a destination, and a storage device that stores a traveled road as a recognized road and stores an extensi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9689689","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.
