PROBLEM TO BE SOLVED: To obtain fresh information and reduce a load on a server.SOLUTION: A traffic support system 10 includes terminal devices 20 which a plurality of users each have, and a traffic support server 60 capable of information communication via a wide-area communication network 84. Each of the terminal devices 20 includes an all-time control unit 42 that provides a user of the terminal device 20 with the state of a wide area WA on the basis of distribution information D received from the traffic support server 60. In addition, it comprises a proximity time control unit 44 that, on the basis that an own terminal 24 of a user mutually comes close to another terminal 26 owned by another user in a specific area SA, performs information communication between the own terminal 24 and the other terminal 26 without going through the traffic support server 60.SELECTED DRAWING: Figure 1 【課題】鮮度の高い情報を得ると共にサーバの負荷を低減する。【解決手段】交通支援システム１０は、複数のユーザがそれぞれ有する端末装置２０と、広域通信網８４を介して情報通信可能な交通支援用サーバ６０と、を含む。端末装置２０は、交通支援用サーバ６０から受信した配信情報Ｄに基づき広範領域ＷＡの状況を端末装置２０のユーザに提供する常時制御部４２を有する。また自端末２４は、他のユーザが有する他端末２６が特定エリアＳＡにおいて相互に接近することに基づき、自端末２４と他端末２６との間で交通支援用サーバ６０を介さずに情報通信を行う接近時制御部４４を備える。【選択図】図１
