PROBLEM TO BE SOLVED: To provide a traffic obstruction risk predicting device that is intended to make vehicle driving safer by predicting the traffic obstruction occurrence risk on the basis of traffic obstruction information transmitted from vehicles to indicate the level of congestion.SOLUTION: A traffic obstruction risk predicting device 10 connected to a traffic obstruction information preparing server 12 that prepares traffic obstruction information comprising the current congestion level obtained from the current value of travel data transmitted from a vehicle 16 as probe data 20 regarding tracks and a statistical level of congestion available from statistical values available for a certain past period before that and to a meteorological information preparing server 14 that prepares meteorological information is equipped with a traffic obstruction risk predicting unit 10b that predicts traffic obstruction occurrence risk indicating the probability of occurrence of traffic obstruction risk on a given track on the basis of the congestion level information drawn on a meshed map set in colors so set as to decrease with a rise in congestion level in numerical values and the meteorological information.SELECTED DRAWING: Figure 1

    【課題】車両から送信される走行データから得られる渋滞度を示す交通障害情報などに基づいて交通障害発生リスクを予測することで一層安全な走行を図るようにした交通障害リスク予測装置を提供する。【解決手段】 走行路について車両16からプローブデータ20として送信される走行データの現況値から得られる現況渋滞度とその過去一定期間の統計値から得られる統計渋滞度からなる渋滞度情報を含む交通障害情報を作成する交通障害情報作成サーバ12と、気象情報を作成する気象情報作成サーバ14とに接続される交通障害リスク予測装置10であって、渋滞度が増加するにつれて減少するように設定される数値で着色してメッシュ地図上に描画される渋滞度情報と気象情報とに基づいて走行路について交通障害が発生する可能性を示す交通障害発生リスクを予測する交通障害リスク予測部10bを備える。【選択図】図1
