Abstract

A communication-based navigation system that detects a traffic volume change and searches for a route. The system comprises terminal retaining geographic information and generating a route request and a traffic condition check request; traffic analysis server having at least one database corresponding to and in communication with the terminal; and service server receiving route request from the terminal for searching for route and transmitting searched route to the terminal and traffic analysis server, and relaying the traffic condition check request from the terminal to traffic analysis server. Traffic analysis server stores in database the searched route from service server and traffic conditions in the searched route and is responsive to the traffic condition check request signal for detecting traffic condition change from comparing a current traffic condition in the searched route with a previous traffic condition stored in the database and for transmitting the traffic condition change.
