To provide a driving assistance device and a computer program with which it is possible to prevent an unrecommended lane change from being made when passing through a toll gate and appropriately conduct driving assistance.SOLUTION: A scheduled travel route that a vehicle travels is acquired; gate information is acquired, the information pertaining to the gate arrangement of a toll gate that exists in the scheduled travel route a prescribed distance or more ahead of the own vehicle position and is to be passed through; map information that includes lane shape and the gate information are used to acquire a candidate for a lane movement manner that is selectable when the vehicle passes through the toll gate along the scheduled travel route; and cost for the acquired candidate for the lane movement manner is calculated, taking into account a lane change position where a lane change is made and the calculated costs are compared, and then the lane movement manner for the vehicle that is recommended when the vehicle passes through the toll gate is selected from the candidates for the lane movement manner.SELECTED DRAWING: Figure 16
【課題】料金所を通過する際に推奨されない車線変更が行われることを防止し、運転支援を適切に実施することを可能にした運転支援装置及びコンピュータプログラムを提供する。【解決手段】車両が走行する走行予定経路を取得し、走行予定経路において自車位置より所定距離以上前方にある通過対象となる料金所のゲートの配置に関する情報であるゲート情報を取得し、レーン形状を含む地図情報とゲート情報とを用いて、走行予定経路に沿って料金所を車両が通過する際に選択し得る車線移動態様の候補を取得し、更に取得された車線移動態様の候補に対して、車線変更を行う車線変更位置を考慮してコストを算出するとともに算出されたコストを比較して車線移動態様の候補の内から料金所を通過する際に推奨される車両の車線移動態様を選択するように構成する。【選択図】図16
