To set an offset that prevents an initial period of a green light from being wasted.SOLUTION: An offset search device according to an aspect of the present disclosure includes: a memory unit that stores input data related to vehicle traffic; and a control unit that performs a search process for offsets to be applied to a plurality of intersections included in a target route using the stored input data, and an index calculation that calculates an evaluation index for each of the plurality of intersections to determine whether the offsets in the search process can be adopted or not. The control unit executes a deceleration suppression process for the intersection for which the evaluation index is to be calculated, adjusting the offsets of the intersection so that the traffic signal of the intersection turns green first when a first vehicle of a vehicle group arrives at the intersection at the green light start time of the intersection.SELECTED DRAWING: Figure 3

    【課題】 青信号の当初期間が無駄になるのを防止できるオフセットを設定する。【解決手段】 本開示の一態様に係る装置は、車両交通に関連する入力データを記憶する記憶部と、記憶した前記入力データを用いて、対象路線に含まれる複数の交差点に適用するオフセットの探索処理と、探索途中の前記オフセットの採用可否を判定するための評価指標を前記複数の交差点ごとに算出する指標算出と、を実行する制御部と、を備えるオフセット探索装置であって、前記制御部は、前記評価指標の算出対象である前記交差点について、当該交差点の青開始時刻に車群の先頭車両が前記交差点に到着する場合に、青信号が先出しされるように前記交差点のオフセットを調整する、減速抑制処理を実行する。【選択図】 図3
