To provide a technique for preparing a travel pattern between railway stations regulated by a diagram which minimizes a collision risk between a train and an obstacle by considering an obstacle detectable distance of an external sensor for detecting the obstacle in front of the train while satisfying a traveling time between stations regulated by the diagram.SOLUTION: A travel pattern preparation device includes a target traveling time recording part which records a target traveling time of a train based on operation information, a restriction pattern recording part which records a restriction pattern produced based on a stoppable speed at a distance where an obstacle on a train traveling area can be detected, an initial pattern producing part which produces an initial pattern where a train travels at a speed of the restriction pattern or less and a correction pattern production part which, when a traveling time in the initial pattern exceeds the target traveling time, produces a correction pattern where a speed partially exceeds the initial pattern and the traveling time becomes within a predetermined time from the target traveling time.SELECTED DRAWING: Figure 2
【課題】ダイヤで規定された駅間の走行時間を満たしつつ、前方の障害物を検知する外界センサの障害物検知可能距離を考慮した、列車と障害物との衝突リスクを最小化する駅間の走行パターンを作成する技術を提供する。【解決手段】走行パターン作成装置は、運行情報に基づく列車の目標走行時分を記録する目標走行時分記録部と、列車走行領域の障害物を検知可能な距離で停止可能な速度に基づいて生成される制限パターンを記録する制限パターン記録部と、制限パターン以下の速度で列車が走行する初期パターンを生成する初期パターン生成部と、初期パターンでの走行時分が目標走行時分を上回る場合に、速度が部分的に初期パターンを上回り、走行時分が目標走行時分から所定時分以内となる修正パターンを生成する修正パターン生成部と、を備える。【選択図】図2
