A navigation device 200 includes an arithmetic device 204 that, when a route including a difficult-to-travel section is found, identifies the route as a candidate route while adding a predetermined penalty cost to the cost of the route, identifies an alternative route obtained by coupling a first partial route from a constituent node in the difficult-to-travel section of the found route to a destination with a second partial route from the departure point of the found route to a node having already been searched for, identifies the alternative route as a candidate route after adding a coupling cost for reaching from the already-searched node to the certain constituent node in the difficult-to-travel section to costs of the first and second partial routes, selects one of the candidate route with the penalty cost and the candidate route with the coupling cost with the smaller cost as a guidance route."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Navigation device, route search server, and route search method","description":"The present invention performs route guidance that excludes a difficult-to-travel section appropriately and provides an alternative route with favorable route quality.
