Route selection method and apparatus therefor.

摘要

A route between a starting point and a destination on a traffic network is derived by searching a first route from the starting point to a first route store point stored in an interpoint route memory (101) and a second route from the destination to a second route store point stored in the interpoint route memory (101), by retrieving a third route between the first and second route store points in the interpoint route memory (101), and by connecting the first, second and third routes to one route. <IMAGE>
