To improve the prediction accuracy of traffic flow and the responsiveness of simulation.SOLUTION: A prediction system includes an arithmetic device that executes predetermined processing, and a storage device that can be accessed by the arithmetic device. The arithmetic device acquires real-time traffic volume data indicating a current traffic volume at a certain observation point and past traffic volume data indicating a past traffic volume on a route including the observation point, calculates an allocated traffic volume, which is the traffic volume for each route, from the past traffic volume data, calculates a coefficient that is a ratio of the traffic volume indicated by the real-time traffic volume data and the allocated traffic volume at the observation point, and corrects the past traffic volume data after the observation point by multiplying the calculated coefficient by the allocated traffic volume so as to generate corrected traffic volume data.SELECTED DRAWING: Figure 1

    【課題】交通流の予測精度を向上し、シミュレーションの応答性を改善する。【解決手段】予測システムであって、所定の処理を実行する演算装置と、前記演算装置がアクセス可能な記憶装置とを備え、前記演算装置は、ある観測点における現在の交通量を示すリアルタイム交通量データと、前記観測点を含む経路における過去の交通量を示す過去交通量データとを取得し、前記過去交通量データから経路毎の交通量である配分交通量を計算し、前記観測点における、前記リアルタイム交通量データが示す交通量と前記配分交通量との比である係数を計算し、前記計算された係数を前記配分交通量に乗じることによって、前記観測点以後の過去交通量データを補正して、補正交通量データを生成する。【選択図】図1
