Disclosed is a lane information generating method that can generate lane information of an increasing or decreasing lane which increases or decreases from a traveling lane with high accuracy is provided. By determining characteristic points based not only on traveling trajectory information of a vehicle but also on the shape of the increasing line of the increasing lane increasing from two traveling lanes, a control unit can complementarily using information of a shape of the increasing line at a position at which variation is easily generated in the traveling trajectory, and thus generate the characteristic points as the lane information of an increasing line with high accuracy.

Lane information generating method

The present invention is to provide a navigation device having a function of starting a route re-searching early by predicting a route change of a vehicle from a recommended route.
