To transmit accident alert information to an information terminal located at an appropriate location.SOLUTION: A traffic information management system in an embodiment comprises: an acquisition unit that acquires current traffic information including at least one of sensor information from a vehicle detection sensor installed on a road and probe information from a vehicle traveling on the road for each of a plurality of sections of the road; an accident occurrence degree calculation unit that calculates an accident occurrence degree for representing the likelihood of the occurrence of an accident with respect to a predetermined timing in the future based on past traffic information, past accident data, and current traffic information as to each of the plurality of sections; a point calculation unit that calculates a current point of a vehicle which reaches the section at a predetermined timing based on a vehicle traveling speed in each section when there is a section in which the accident occurrence degree is greater than or equal to a threshold; and a transmission control unit that transmits accident alert information for the section to an information terminal located on an upstream side of the road from the point.SELECTED DRAWING: Figure 6
【課題】事故注意喚起情報を適切な位置の情報端末に送信する。【解決手段】実施形態における交通情報管理システムは、道路の複数の区間ごとに、道路に設置されている車両感知センサからのセンサ情報、および、道路を走行する車両からのプローブ情報の少なくともいずれかを含む現在交通情報を取得する取得部と、複数の区間それぞれについて、過去交通情報および過去事故データと、現在交通情報と、に基づいて、将来の所定タイミングに関して、事故の発生しやすさを表す事故発生度を算出する事故発生度算出部と、事故発生度が閾値以上である区間があった場合に、それぞれの区間での車両走行速度に基づいて、所定タイミングに当該区間に到達する車両の現在の地点を算出する地点算出部と、地点よりも道路の上流側に位置する情報端末に、当該区間の事故注意喚起情報を送信する送信制御部と、を備える。【選択図】図6
