PROBLEM TO BE SOLVED: To provide a traffic event estimation system capable of estimating a traffic event that has unexpectedly or temporarily occurred in a manner different from that of a normal case.SOLUTION: A traffic event estimation device 1 acquires probe information including the position information, speed information, and time information of multiple vehicles C travelling on a road R, and estimates a traffic event on the basis of the acquired probe information of the respective vehicles C. Specifically, the traffic event estimation device 1 includes: a first specification section for specifying the travel states of the vehicles C in each one of multiple links constituting the road R for each predetermined time zone on the basis of the probe information acquired over the first predetermined period; a second specification section for specifying the travel states of the vehicles C in the links on the basis of the probe information acquired over the second predetermined period shorter than the first predetermined period; and an event estimation section for estimating a traffic event on the basis of the travel states specified by the first specification section and the second specification section.SELECTED DRAWING: Figure 1

    【課題】平常時と異なる突発的ないし一時的に生じた交通事象を推定することができる交通事象推定システムを提供する。【解決手段】交通事象推定装置1は、道路Rを走行する複数の車両Cの位置情報、速度情報及び時間情報を含むプローブ情報を取得し、取得した各車両Cのプローブ情報に基づいて交通事象を推定する。具体的には、交通事象推定装置1は、道路Rを構成する複数のリンクそれぞれにおける車両Cの走行状態を、第1所定期間にわたって取得したプローブ情報に基づいて、所定の時間帯毎に特定する第1特定部と、前記第1所定期間よりも短い第2所定期間にわたって取得したプローブ情報に基づいて、前記リンクにおける車両Cの走行状態を特定する第2特定部と、前記第1特定部及び前記第2特定部にて特定した走行状態に基づいて、交通事象を推定する事象推定部とを備える。【選択図】図1
