To make it possible to more quickly notify a mobile unit in which collision risk increases of traffic information in a traffic information notification system for notifying a plurality of mobile units of the traffic information.SOLUTION: A center device 2 includes: a position information acquisition unit 32 for acquiring position information of a plurality of mobile units; a collision risk degree estimation unit 34 for estimating probability of collision of each mobile unit based on the position information of each mobile unit; a communication route setting unit 36 for setting a communication route of traffic information so that the traffic information is directly notified to the mobile unit having a high collision risk and the other mobile unit is notified by inter-mobile unit communication according to the collision risk of each mobile unit; and a traffic information notification unit 38 for transmitting notification information including the traffic information and the communication route to be notified to each mobile unit to a mobile unit having the high collision risk.SELECTED DRAWING: Figure 2

    【課題】複数の移動体に交通情報を通知する交通情報通知システムにおいて、衝突等の危険性が高くなる移動体に対し、交通情報をより早く通知できるようにする。【解決手段】センタ装置2は、複数の移動体の位置情報を取得する位置情報取得部32と、各移動体の位置情報に基づき各移動体が衝突する確率を推定する衝突危険度推定部34と、各移動体の衝突危険度に応じて、衝突危険度が大きい移動体には交通情報が直接通知され、他の移動体には移動体間通信によって通知されるように交通情報の通信経路を設定する通信経路設定部36と、各移動体に通知すべき交通情報と通信経路とを含む通知情報を衝突危険度が大きい移動体に送信する交通情報通知部38とを備える。【選択図】図2
