Route information conversion system, route information transmission apparatus, and route information reception apparatus

A route information conversion system includes a route information transmission apparatus and a route information reception apparatus. The route information transmission apparatus includes: a route search unit that generates a search result of a route with reference to first map data; a position reference information generation unit that generates position reference information indicating a road corresponding to the search result; and a peripheral road information generation unit that generates peripheral road information indicating a road branching from the road corresponding to the search result. The route information reception apparatus includes: a route information restoration unit that restores route information on second map data from the position reference information; and a route match determination unit that determines whether the search result on the first map data and the route information on the second map data match each other with reference to the peripheral road information.
