You can search.

That is, when the point of interest is first searched for, the point of interest search unit 50 searches for the point of interest corresponding to the POI information input by the user only for an area within a first set distance from the driving route. By limiting the point search area, a point of interest located far from the driving route can be excluded from the search target.

In addition, when the POI is secondary searched and additionally searched, the POI search unit 50 searches for the POI corresponding to the POI information input by the user only for an area within a second set distance from the retrieved POI. By limiting the POI search region through the method, POIs located far from the driving route can be excluded from the search target.

The first set distance and the second set distance may be preset in the POI search unit 50 according to the designer's intention, or may be set in a manner that the user inputs through the input unit 10 (eg, the first set distance). Set distance: 500m, 1km, 5km, Second set distance: 500m, 1km).

In addition, when the POI is secondary searched and additionally searched, the POI search unit 50 allows the user to input only an area within the second set distance from the searched POI and the first set distance from the driving route. It is also possible to search for a point of interest corresponding to one POI information.

That is, by substantially limiting the POI to be searched in the primary search, the secondary search, and the continuous additional search process to the POI existing within the first set distance from the driving route, the POI during the secondary search and the additional search process is It is also possible to prevent the POI located at a long distance from the driving route from being searched for by the derivative search.

The additional information providing unit 90 may provide additional information on the POI input (selected) by the user among the POIs displayed through the display unit 80 . The additional information on the POI means detailed information such as the type of business, service, business hours and location of the POI, and the additional information providing unit 90 is implemented as an external server of the portal site to provide detailed information of the POI. can be
