To provide a change system capable of appropriately supporting driving for a driver under a reverse traveling state, and a change program.SOLUTION: A change system comprises: a support necessity determination unit 181 for determining the necessity of a reverse traveling prevention support for a driver of a vehicle; and a change unit 182 for changing a road defined as a matching object that is a candidate to be identified as a traveling road of the vehicle, according to a determination result of the support necessity determination unit 181. In a case where the support necessity determination unit 181 determines that the reverse traveling prevention support is not required, the change unit 182 defines a road on which the vehicle can travel forwards with a present direction of travel of the vehicle defined as a reference, as the matching object and, in a case where the support necessity determination unit 181 determines that the reverse traveling prevention support is required, defines a road on which the vehicle can travel forwards with the present direction of travel of the vehicle defined as the reference, and a road in a reverse direction of the forward direction as the matching object.SELECTED DRAWING: Figure 1
【課題】逆走している運転者に対して運転を適切に支援することが可能となる変更システム、及び変更プログラムを提供すること。【解決手段】車両の運転者に対する逆走防止支援の要否を判定する支援要否判定部181と、支援要否判定部181の判定結果に基づいて、車両の走行道路として特定する候補であるマッチング対象とする道路を変更する変更部182と、備え、変更部182は、逆走防止支援が不要であるものと支援要否判定部181が判定した場合に、車両の現在の進行方向を基準に順方向として走行可能な道路をマッチング対象とし、逆走防止支援が必要であるものと支援要否判定部181が判定した場合に、車両の現在の進行方向を基準に順方向として走行可能な道路、及び当該順方向とは逆方向の道路を前記マッチング対象とする。【選択図】図1
