To forecast an amount of vehicle inflow from a predetermined entrance to a road with high accuracy.SOLUTION: A traffic forecasting device comprises: an acquisition unit that acquires traffic information from a traffic information collection device that collects traffic information of vehicles on a road; a generation unit that generates a forecast model by using at least an amount of past vehicle inflow earlier than a predetermined timing from a predetermined exit around an entrance on the basis of traffic information when generating a forecast model that forecasts the amount of vehicle inflow from the predetermined entrance to the road at a predetermined timing; and a forecasting unit that forecasts the amount of vehicle inflow from the entrance on the basis of the forecast model and the amount of vehicle inflow earlier than a forecast target timing from the exit obtained by the traffic information when forecasting the amount of vehicle inflow from the entrance at a future forecast target timing.SELECTED DRAWING: Figure 5
【課題】道路への所定の入口からの車両流入量を高精度に予測する。【解決手段】実施形態における交通予測装置は、道路における車両の交通情報を収集する交通情報収集装置から交通情報を取得する取得部と、所定タイミングにおける道路への所定の入口からの車両流入量を予測する予測モデルを作成する際に、交通情報に基づいて、少なくとも、入口の周辺の所定の出口からの所定タイミングより過去の車両流出量を用いて、予測モデルを作成する作成部と、将来の予測対象タイミングにおける入口からの車両流入量を予測する際に、予測モデルと、交通情報から得られる出口からの予測対象タイミングより過去の車両流出量と、に基づいて、入口からの車両流入量を予測する予測部と、を備える。【選択図】図5
