Abstract

A route search method considering the linearity of a route includes: once an arriving is inputted, searching a route to the arriving; when the searched routes are more than two, obtaining linear type information for each of the searched routes; and selecting one of the routes according to the linear type information.

Claims

1. A route search method considering the linearity of a route, the method comprising:

once an arriving is inputted, searching a route to the arriving;

when the searched routes are more than two, obtaining linear type information for each of the searched routes; and

selecting one of the routes according to the linear type information.

2. The method of claim 1, wherein the linear type information comprises plane linear type information and vertical linear type information.

3. The method of claim 2, wherein the selecting of one of the routes comprises selecting a route having a relatively large curve radius of the plane linear type information from the routes.

4. The method of claim 2, wherein the selecting of one of the two routes comprises selecting a route having a relatively small vertical slope of the vertical linear type information from the routes.

5. The method of claim 1, wherein the obtaining of the linear type information for each of the searched routes comprises:

confirming an average travel time of the searched route;

selecting a predetermined number of the routes from the searched routes in an order from the smallest to largest average travel time; and

obtaining linear type information of the selected route.
