To provide a technique for suppressing deterioration in accuracy of traffic information.SOLUTION: A traffic information generation system comprises: a congestion section acquisition portion for acquiring a congestion section; a probe information acquisition portion for acquiring probe information including a vehicle position and vehicle speed; and a congestion tail update portion for acquiring a deceleration position that is a vehicle position of a probe vehicle of which vehicle speed becomes a predetermined speed or less on the probe information, and updating a tail position of the congestion section on the basis of the deceleration position. A period for collecting the deceleration positions used for updating the tail position of the congestion section when updating the tail position from a facility where a vehicle is temporarily stopped to a predetermined section which is a section within a predetermined distance is longer than a period when updating the tail position to the outside of the predetermined section.SELECTED DRAWING: Figure 1

    【課題】交通情報の精度低下を抑制する技術の提供。【解決手段】渋滞区間を取得する渋滞区間取得部と、車両位置と車速とを含むプローブ情報を取得するプローブ情報取得部と、前記プローブ情報に基づいて、車速が既定速度以下となったプローブ車両の車両位置である減速位置を取得し、前記減速位置に基づいて前記渋滞区間の末尾の位置を更新する渋滞末尾更新部と、を備え、前記渋滞区間の末尾の位置を更新するために用いられる前記減速位置を収集する期間は、車両が一時的に停止する施設から既定距離以内の区間である既定区間内に更新する場合の方が前記既定区間外に更新する場合よりも長い、交通情報生成システムを構成する。【選択図】図1
