In this case, the search results 501 may be sorted in alphabetical order or distance according to a setting, and may be displayed on the screen including information such as a place name and address. The terminal 10 transmits the information on the keyword to the POI providing apparatus 20.

Thereafter, the terminal 10 receives the route information 503 for the plurality of POIs to which the traffic information is applied from the route search apparatus 30, and outputs the received route information 503 on the screen. In this case, the route information may display the distance to the corresponding POI and the estimated time of arrival. In addition, the terminal 10 may add events, events, or weather around the plurality of POIs in order to increase the reliability of the estimated time of arrival. The information may be collected, and the estimated time of arrival to the corresponding destination may be calculated by combining the collected additional information and the traffic information.

The terminal 10 sets the POI corresponding to the specific route information 505 selected by the user among the plurality of route information 503 as a destination, and performs route guidance to the destination.

As illustrated in FIGS. 6A to 6C, the terminal 10 confirms an initially confirmed estimated arrival time and an estimated arrival time when driving in a current state while the vehicle is traveling along a specific route. If the terminal 10 determines that the estimated time of arrival from the current location 601 to the destination 603 is delayed compared to the initially set estimated time of arrival, the terminal 10 displays a popup message 605 on the screen. In this case, the pop-up message is not displayed in full screen so as not to interfere with driving, but is provided to one side of the map information displayed through the navigation application. For example, a pop-up message might say, "The estimated time of arrival is delayed. Would you like to use a different POI?" May be displayed.

When the path reset is requested in response to the pop-up message, the terminal 10 requests the path search apparatus 30 to search for the path again. In addition, the terminal 10 may check a time required until the POI searched again based on the current location 601, change the destination according to a user setting, and provide a route guidance to the corresponding destination 607. .

The present invention collects traffic information for a plurality of POIs from a search result associated with a specific keyword, and provides route guidance to a specific POI after applying the collected traffic information to the plurality of POIs. Accordingly, since the navigation providing system searches for and provides information of interest mainly on the estimated time of arrival (required time) to which the actual traffic conditions are applied, the navigation providing system is effective in providing a route. In addition, there is no inconvenience of separately checking the time required for the various POIs, and since only the POIs that the user wants to check are collectively checked, the time for the route search is saved and convenient. In addition, if the estimated time of arrival to the destination is delayed compared to the initially set estimated time of arrival while driving by selecting a specific POI, the user may be re-collected to reset the estimated time of arrival by re-collecting traffic information about another selected POI. It provides a route to a POI that is relevant to a quickly entered keyword. This has industrial applicability because it is not only sufficient marketable or business possibility, but also practically evident.
