5 is a menu configuration screen on a display unit of an information terminal providing a function of selecting a route and a means of transportation.

Referring to FIG. 4, the user selects a navigation menu basically provided by the information terminal 110 (S410).

When the controller 320 displays an input screen or a map screen for selecting a starting point or a destination on the display unit 370, the user requests a route for reaching the destination from the starting point by inputting the starting point or the destination (S420).

Here, the starting point or the destination may be location information of the point where the information terminal 110 is currently located, and may be input in a text form from the user or according to a user's designation on a map image.

At this time, the position information of the point where the information terminal 110 is currently located is received from the GPS satellite 122 through the GPS receiver 310.

Referring to FIG. 5, a starting point and a destination may be input as text in the input window 501 or a starting point and a destination may be selected on a map image by using a map button 502.

Since it is inefficient to display all the paths from the starting point to the destination on the display unit, the user can set the route variable (S430).

When traveling from the starting point to the destination, various routes are generated by cost, distance, travel time, and number of transfers. In this case, cost, movement distance, travel time, and number of transfers that affect the occurrence of the route will be defined as route variables. .

For example, if the user prioritizes only the minimum cost, the controller 320 searches only the optimal cost path regardless of the distance, travel time, and the number of transfers, and arranges the paths sequentially on the display unit 370 in the order of least cost.

Referring to FIG. 5, in the path variable setting 503, a path variable desired by a user may be selected from among costs, distances, times, and transfer times.

For the convenience of the user, the information terminal 110 allows the user to designate one or more of public transportation, that is, bus, subway, taxi, so that the user can preferentially select a public transportation to use.

For example, when the user selects only a bus, the controller 320 of the information terminal searches only a route using a bus, and when a plurality of buses and subways are selected, a bus and a subway are used as well as a bus and a subway. Navigate the route, even if used. If the user has selected all possible modes of transportation, then all possible routes from the origin to the destination are searched.

Referring to FIG. 5, a user may select from among buses, subways, and taxis in the public transportation setting 504.

However, when the search result is displayed on the display unit 370, only the cost may be displayed according to the user's selection, and at least one of the distance, the moving time, and the transfer number may be simultaneously displayed as well as the cost.

The real-time public traffic situation information or the operation information of the public transportation means is received from the public transportation system through the broadcast receiving module 340 of the information terminal and stored in the public transportation information storage unit 350.

The information terminal 110 may allow a user to select whether to use real-time traffic situation information. If the user requests the use of real-time traffic information, the information terminal 110 receives real-time public traffic situation information from a traffic guidance system (not shown) through the broadcast receiving module 340 and avoids a congestion section according to the current traffic situation. The travel time is calculated by reflecting the delay time due to searching the route or congestion. In addition, when calculating the travel time, using the real-time traffic status information reflects the waiting time according to the public transportation boarding, the travel time according to the transfer.

Then, when the user requests the route guidance (S460), the controller 320 of the information terminal 110 drives the GPS receiver 310 of the information terminal 110 by referring to the route information stored in the map data storage 360. In order to start the route guidance (S470).

While guiding the route, the state of the information terminal may be changed to an idle mode according to a user's selection, or the state of the information terminal may be reactivated to leave the route or re-search the route.

When the information terminal 110 reaches the transfer point or the destination point based on the route information, the information terminal 110 may notify the user by at least one of voice and text according to the user's selection.

In addition, when the user reaches the transfer point, the information terminal 110 may request the arrival schedule information of the public transportation from the traffic information guide system (not shown) through the broadcast receiving module 250.

For example, a user may take a subway and get off at Yeoksam Station to transfer to a bus. When the user inputs the station "Yeoksam Station" or "bus number" to search for the arrival time of the bus, information on the bus that is expected to arrive near Yeoksam Station is displayed.

As another embodiment of the present invention, a location of an information terminal of another user may be searched and set as a destination. When the information terminal of another user is the destination, the information terminal may be divided according to whether the information terminal set as the destination is moved.

When the information terminal set as the destination is fixed without moving, the destination information is not the user inputting the destination information but the destination information, but the fixed current position of the information terminal of another user.

As another example, there may be a case where an information terminal set as a destination promises to meet at a third place by moving at the same time as the information terminal set as a starting point. That is, there may be a case where the users of the information terminals set as the starting point and the destination at the same time at the third appointment place meet to meet each other.

The GPS receiver 310 of the information terminal 110 set as a starting point receives location information (latitude and longitude information) from the GPS satellite 122, and the GPS satellite 122 searches for the location of another user's information terminal to obtain destination information. Is provided to the information terminal 110 set as a starting point.
