To provide a lane change information providing device and a lane change information providing method that make it possible to change lanes appropriately even during driving on the road highly difficult to drive on.SOLUTION: A route guiding device 100 comprises: a route searching unit 11 for searching a to-be-guided route; a limited speed acquisition unit 12 for acquiring a limited speed of a road leading to a guide point along on the to-be-guided route searched by the route searching unit 11; and a route guiding unit 13 for performing the guidance of the lane change in which it is recommended to carry out before arriving at the guide point at an earlier timing while the limited speed acquired by the limited speed acquisition unit 12 is lower; whereby, during the guidance to the to-be-guided route, the guidance related to the lane change is performed at an earlier timing while the limited speed of the road is lower on the road leading to the guide point.SELECTED DRAWING: Figure 1
【課題】運転の難易度が高い道路を走行中でも適切に車線変更を行えるようにした「車線変更情報提供装置および車線変更情報提供方法」を提供する。【解決手段】経路案内装置100は、誘導経路を探索する経路探索部11と、経路探索部11により探索された誘導経路上の案内地点に至る道路の制限速度を取得する制限速度取得部12と、案内地点に至る前に行うことを推奨する車線変更の案内を、制限速度取得部12により取得された制限速度が小さいほど早いタイミングで実行する経路案内部13とを備え、これにより、誘導経路の案内中、案内地点に至る道路において、その道路の制限速度が小さいほど、早いタイミングで車線変更に関する案内を実行する。【選択図】図1
