To predict a traffic jam with high accuracy from the traffic condition of vehicles in a specific section of a road.SOLUTION: A traffic condition acquisition system acquires a traffic condition in a specific section of a road which vehicles pass. The traffic condition acquisition system includes: an inflow information acquisition unit that acquires inflow vehicle information; an outflow information acquisition unit that acquires outflow vehicle information; and a traffic condition acquisition unit that acquires a traffic condition from the inflow vehicle information and the outflow vehicle information. The traffic condition acquisition unit calculates the number of accumulative vehicles from the number of inflow vehicles and the number of outflow vehicles and predicts the occurrence of a traffic jam on the basis of the number of accumulative vehicles and the number of saturated vehicles.SELECTED DRAWING: Figure 2

    【課題】道路の特定区間における車両の交通状態から精度の高い渋滞予測を行う。【解決手段】車両が通過する道路の特定区間内の交通状態を取得する。交通状態取得システムは、流入車両情報を取得する流入情報取得部と、流出車両情報を取得する流出情報取得部と、前記流入車両情報及び前記流出車両情報から交通状態を取得する交通状態取得部と、を有し、前記交通状態取得部は、前記流入車両数と前記流出車両数とから蓄積車両数を算出し、前記蓄積車両数及び前記飽和車両数に基づいて渋滞の発生を予測する。【選択図】図2
