METHOD AND APPARATUS UTILIZING BOTH STATISTICAL AND REAL TIME DATA FOR A VEHICLE NAVIGATION SYSTEM

摘要

A method for determining a preferred route of road links between an origin and a destination in a vehicle navigation system. A boundary is established the origin and a destination and real time road link data is acquired for road links between the origin and the boundary. Similarly, road link data from a statistical database is retrieved from a road link database for road links between the boundary and the destination. The preferred route between the origin and the destination is then calculated as a function of both said real time road link data and statistical road link data and the calculated route is displayed on a screen.
