PROBLEM TO BE SOLVED: To provide a travel difficult section determination system capable of properly determining a travel difficult section which is based on an actual situation.SOLUTION: A travel difficult section determination system (1) comprises: a first position detection part (31) for detecting a first position of a vehicle along a travel direction; a second position detection part (33) for detecting a second position of the vehicle along a road width direction; a position information output part (34) for outputting information containing the first position at a place where it is determined that a clearance between the second position and a central position or an end position of a lane where a vehicle is traveling, is out of a proper range, as a candidate position information (CP); and a determination part (51) for determining a travel difficult section based on the candidate position information (CP).SELECTED DRAWING: Figure 1

    【課題】実情に即した走行困難区間を適切に判定することができる走行困難区間判定システムを実現する。【解決手段】走行困難区間判定システム(1)は、走行方向に沿う車両の第一位置を検知する第一位置検知部(31)と、道路幅方向に沿う車両の第二位置を検知する第二位置検知部(33)と、第二位置と走行中レーンの中央位置又は端部位置との離間距離が適正範囲外であると判定された地点における第一位置を含む情報を候補位置情報(CP)として出力する位置情報出力部(34)と、候補位置情報(CP)に基づいて走行困難区間を判定する判定部(51)と、を備える。【選択図】図1
