The processor determines whether the turning costs are different between the sets of nodes. In addition, the processor calculates a driving risk degree from the i-th node to the (i+1)-th node when the turning direction from the i-th node to the (i+1)-th node is different from the turning direction from the (i+1)-th node to the (i+2)-th node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Route searching method of navigation system and apparatus therefor","description":"A route searching method of a navigation system is provided and includes calculating, by a processor, a turning cost from an i-th node to an (i+1)-th node and a turning cost from the (i+1)-th node to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9671240","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.
