To avoid problems in the prior art without installing a new sensor or the like and detect an occurrence of a sudden event on a road.SOLUTION: A sudden event detection system of an embodiment includes: a sensor data acquisition unit that acquires sensor data concerning a vehicle traveling on a road; a theoretical traffic situation estimation unit that using the sensor data, estimates a theoretical traffic situation in a case where there is no sudden event occurred on the road on the basis of a predetermined algorithm based on a traffic engineering theory; a current traffic situation recognition unit that calculates a current actual traffic situation using the sensor data; and a sudden event determination unit that compares the theoretical traffic situation and the current actual traffic situation and in a case where there is a difference more than or equal to a predetermined threshold value, determines that a sudden event occurs on the road.SELECTED DRAWING: Figure 12
【課題】新たなセンサなどを設置しなくても従来技術の問題点を回避し、道路における突発事象の発生を検知する。【解決手段】実施形態の突発事象検知システムは、道路を走行する車両に関するセンサデータを取得するセンサデータ取得部と、前記センサデータを用いて、交通工学理論に基づく所定アルゴリズムに基づいて、前記道路において突発事象が発生していない場合の理論的な交通状況を推定する理論的交通状況推定部と、前記センサデータを用いて、現在の実際の交通状況を算出する現在交通状況把握部と、前記理論的な交通状況と、前記現在の実際の交通状況と、を比較し、所定閾値以上の差異がある場合に前記道路において突発事象が起きていると判定する突発事象判定部と、を備える。【選択図】図12
