Routing guide mediation system, routing guide mediation server, and routing guide method

摘要

A routing guide mediation system is equipped with a routing guide mediation server, establishing cooperation between a plurality of routing guide systems having map data by country and region and network data for route search. When a departure point and a destination are points in different areas, a first route search server extracts a candidate contact point which will be the boundary between the different areas, and transmits it to a second route search server via the routing guide mediation server. Then, the first and second route search servers search for an optical route from the departure point to the candidate contact point and an optimal candidate route from the candidate contact point to the destination, individually, and the first route search server acquires the amounts of time required for these routes and link data via the routing guide mediation server.
