NAVIGATION SERVER AND NAVIGATION SYSTEM

摘要

Disclosed is a navigation system which creates "environment contribution information" in accordance with deviation (d(k)) between the total cost (C1(k)) of a first route (RT1(k)) which is searched using traffic information indicating the amount of the cost required to pass through each link, and the total cost (C2(k)) of a second route (RT2(k)) which is searched without using the traffic information. The traffic information used when the first route (RT1(k)), which leads to a target location (TP(k)) of a vehicle (2), is searched is used when a route to a shared target location is searched by means of a navigation device (200).
