Navigation apparatus for vehicle, generates branch model diagram, based on connection relationship of approach and recession paths, number of lanes, with reference to branch pattern data

摘要

A CPU (4) acquires branch information from map data stored in memory (3) and searches the connection relationship of approach and recession paths, and number of lanes from the acquired branch information. The branch model diagram is generated based on the searched data, with reference to branch pattern data included in map data. An Independent claim is also included for memory medium.
