Disclosed is a telematics system comprising a telematics terminal for storing complex intersection images and providing information related to a present position and a running direction by using the complex intersection images, and a telematics server for sharing ID codes of the complex intersection images stored in the telematics terminal with the telematics terminal and creating route data in response to a request from the telematics terminal, wherein the telematics server adds the ID codes of the complex intersection images to the route data when the route data include complex intersections and transmits the ID codes of the complex intersection images and the route data to the telematics terminal. The telematics system provides route information, which is easily recognized by users.

Disclosed is a single or multi-route map matching apparatus in a system which provides a navigation service via a mobile communication terminal. The map matching apparatus comprises: an information center for calculating an optimum route to a destination inputted by a user based upon a present location of the mobile communication terminal, and generating a format of route data based upon the calculated optimum route; and an Intelligent Transportation System (ITS) terminal for detecting the present location of the mobile terminal to generate location data, processing the route data, performing map matching based upon the location data to determine whether the user travels on a given route or departs from the route, and performing road guidance based upon a result of the map matching.

Single or multiple route map matching apparatus for navigation service and method thereof

A route guiding method for an in-vehicle navigation device. To guide a vehicle to a destination by an optimum route, it is determined whether the vehicle is on track within a predetermined intersection range based on route guidance data received from a traffic information center via a mobile communication network. If the vehicle is on track within the intersection range, it is determined whether the vehicle is in a free run state according to predetermined free run conditions to prevent a preliminary route guidance message that is confusing to a driver in the free run state. According to the determination result, the preliminary route guidance message is selectively provided.
