NAVIGATION SYSTEM, ROUTE SEARCHING SERVER, PORTABLE TERMINAL DEVICE AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To guide the optimum guide route by optimizing the transfer time in a junction place to the transfer time according to the real state in a navigation system for searching and guiding a route from a starting place to a destination including transfer of trains utilizing transportation.

SOLUTION: A route searching system 10 having a route searching server 30 and a portable terminal device 20 includes: a transfer time DB38 accumulating the transfer time in the junction place; a transfer time collecting means 35 collecting the transfer time from the portable terminal device 20; and a statistical processing means 37 for statistical processing the data on the transfer time of every junction place collected by the transfer time collecting means 35 to calculate the transfer time by each junction place, wherein the transfer time accumulated in the transfer time DB38 is updated by the transfer time calculated by the statistical processing means 37.
