To estimate a traffic situation of a load at high accuracy even if the number of vehicle detection devices that measure the number of passing vehicles is small.SOLUTION: A traffic situation estimation system according to the embodiment comprises: a passing vehicle number information acquisition part; a passing time information acquisition part; a reference accumulative traffic mount calculation part; a pseudo accumulative traffic amount generation part; and a traffic situation estimation part. The reference accumulative traffic mount calculation part calculates a reference accumulative traffic mount as an accumulative value of the number of vehicles passing through a reference point on the basis of passing vehicle number information. The pseudo accumulative traffic amount generation part generates a pseudo accumulative traffic amount as an accumulative value of the number of vehicles passing through a prescribed point other than the reference point in the load on the basis of the reference accumulative traffic amount and the passing through time information. The traffic situation estimation part estimates the traffic situation of the load on the basis of the reference accumulative traffic amount and the pseudo accumulative traffic amount.SELECTED DRAWING: Figure 2

    【課題】道路に設置されていて車両の通過台数を計測する車両検知装置の数が少なくても、道路の交通状況を高精度で推定する。【解決手段】実施形態における交通状況推定システムは、通過台数情報取得部と、通過時刻情報取得部と、基準累積交通量算出部と、擬似累積交通量作成部と、交通状況推定部と、を備える。基準累積交通量算出部は、通過台数情報に基いて、基準地点を通過した車両の台数の累積値である基準累積交通量を算出する。擬似累積交通量作成部は、基準累積交通量と、通過時刻情報と、に基いて、道路における基準地点以外の所定の地点を通過した車両の台数の累積値である擬似累積交通量を作成する。交通状況推定部は、基準累積交通量と、擬似累積交通量と、に基いて、道路の交通状況を推定する。【選択図】図2
