To provide technology to achieve higher safety for vehicles with automatic driving or driving support functions in a system that provides information on signal indications pertaining to intersections.SOLUTION: A signal information provision system 1 sets limit points, which indicate a permissible limit position of the travel of a vehicle 30 passing through an intersection, for each direction of entry into the intersection based on signal change point information, and transmits signal information pertaining to the intersection, including the signal change point information and the limit point information, to the vehicle 30 traveling in a predetermined range that includes the intersection. The limit points include absolute limit points where driving beyond the limit points is controlled by the driving control function of automatic driving or driving support of the vehicle 30 to deter driving beyond the limit points, and temporary limit points where driving beyond the limit points is determined based on the signal information at an adjacent intersection.SELECTED DRAWING: Figure 1

    【課題】交差点に係る信号現示の情報を提供する仕組みにおいて、自動運転又は運転支援の機能を有する自動車にとって、より高い安全性を実現するための技術を提供すること。【解決手段】信号情報提供システム1は、交差点を通過する際の自動車30の進行許容限界位置を示す限界点を信号変化点情報に基づいて交差点への進入方向別に設定し、信号変化点情報と限界点の情報とを含む当該交差点に係る信号情報を、交差点を含む所定範囲を走行する自動車30に向けて発信する。限界点には、自動車30の自動運転又は運転支援の走行制御機能によって、当該限界点を越える走行を抑止する制御がなされる絶対限界点と、隣接交差点の信号情報に基づいて当該限界点を越える走行の許否が判定される仮設限界点とがある。【選択図】図1
