PROBLEM TO BE SOLVED: To easily provide highly accurate congestion prediction information of each mesh-like area without making a user set a destination at a client side on the basis of probe data.SOLUTION: The traffic congestion prediction device comprises: a congestion stop vehicle determination part 304 for determining a vehicle involved in a congestion in each area of a map; a congestion stop vehicle number calculation part 305 for calculating the number of congestion stop vehicles in each area of the map; a congestion escape vector calculation part 306 for calculating an escape direction and escape speed from each area; a congestion stop vehicle prediction part 307 for predicting the number of congestion stop vehicles in each area after a fixed time; and a congestion degree prediction part 308 for predicting a degree of congestion in each area after the fixed time.SELECTED DRAWING: Figure 1
【課題】プローブデータに基づいて、メッシュ状の領域毎の渋滞予測情報をクライアント側でユーザーが目的地を設定することなく、簡便に精度の高い渋滞予測を行うこと。【解決手段】地図の各領域内で渋滞に巻き込まれている車両を判定する渋滞停止車両判定部３０４と、地図の各領域毎に渋滞停止車両の台数を算出する渋滞停止車両台数算出部３０５と、各領域からの脱出方向と脱出速度を算出する渋滞脱出ベクトル算出部３０６と、各領域の各々について、一定時間後の各領域における渋滞停止車両台数を予測する渋滞停止車両予測部３０７と、一定時間後の各領域の渋滞度を予測する渋滞度予測部３０８と、を備える交通渋滞予測装置。【選択図】図１
