To provide road traffic information with a designated date and time in the future with high accuracy.SOLUTION: A statistical traffic information processing system 100 includes a roadside device 1, an on-vehicle device 3 mounted on a vehicle 2, and a statistical traffic information management server 5. The on-vehicle device 3 forms intersection traffic information c2 including an intersection ID and a passing date/time, and transmits the intersection traffic information c2 to a server 5 in the case where the on-vehicle device determines that the vehicle 2 has passed an intersection on the basis of intersection information c1 received from the roadside device 1 and position information of the vehicle 2. The server 5 classifies the received intersection traffic information c2 on the basis of the intersection ID and a predetermined time zone to which the passing date/time belongs, and the server forms, as statistical traffic information, the intersection ID and the number of passing vehicles 2 collected for each predetermined time zone, and stores the statistical traffic information into a statistical traffic information DB 51.SELECTED DRAWING: Figure 1
【課題】未来の指定日時の道路交通情報を精度高く提供する。【解決手段】統計交通情報処理システム100は、路側装置1と、車両2に搭載された車載装置3と、統計交通情報管理サーバ5と、を備える。車載装置3は、路側装置1から受信した交差点情報c1と車両2の位置情報に基づいて、車両2が交差点を通過したと判定した場合、交差点ID及び通過日時を含む交差点交通情報c2を作成し、サーバ5に送信する。サーバ5は、受信した交差点交通情報c2を交差点ID及び通過日時が属する所定の時間帯に基づいて分類し、交差点ID及び所定の時間帯ごとに集約された車両2の通過台数を統計交通情報として作成し、統計交通情報DB51に記憶する。【選択図】図1
