ROUTE SEARCH SYSTEM, DATA PROCESSOR, DATA DISTRIBUTION APPARATUS, AND NAVIGATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a route search system for searching for routes capable of facilitating the passage of a vehicle, a data processor, a data distribution apparatus, and a navigation system. SOLUTION: Probe information transmitting devices 4-6 mounted to probe cars 1-3 transmit probe information on the traveling state of each probe car. A data processing center collects the probe information and computes a count value indicating the number of probe cars passed through each road on the basis of collected probe information. The data distribution center or the navigation system 10 searches for a route through which a vehicle should travel on the basis of the count value computed in this way. COPYRIGHT: (C)2009,JPO&INPIT
