To support a traffic support technique for local district, capable of achieving low cost, high versatility and effective provision of traffic information in real time.SOLUTION: A traffic information transmission device 230, installed in the vicinity of a local district at which a plurality of roads cross or join each other and notifying a vehicle of traffic information on the basis of vehicle traveling information detected by a sensor 210 installed on each of the roads, includes: a first transmission device which creates first transmission data including direction specific information for specifying a direction to the traffic information transmission device on a vehicle running road for each vehicle and transmits the data at a first time interval; and a second transmission device which calculates traffic information of each of the roads on the basis of the traveling information received by the sensor and creates the direction of each of the roads as second transmission data in determinable mode by combining the latest traffic information on all roads in a support region of the traffic information transmission device with the direction specific information for all vehicles in the support region and which transmits the data at a second time interval shorter than the first time interval.SELECTED DRAWING: Figure 1

    【課題】低コストで汎用性が高く、リアルタイムな交通情報を効果的に提供可能な局所向き交通支援技術を提供する。【解決手段】複数の道路が交差または合流する局所近傍に設置され、各道路上に設置されたセンサ210により検知した車両の走行情報を基に、車両に向けて交通情報を通知する交通情報送信装置230であって、各車両に対し、当該車両が走行中の道路の、当該交通情報送信装置に対する方向を特定する方向特定情報を含む第一送信データを生成し、第一時間間隔で送信する第一送信装置と、センサより受信した走行情報に基づき、各道路の交通情報を算出し、当該交通情報送信装置の支援領域内の全車両に対し、当該支援領域内の全道路の最新の交通情報を、方向特定情報と組み合わせることで各道路の方向を判別可能な態様で第二送信データとして生成し、第一時間間隔より短い第二の時間間隔で送信する第二送信装置と、を備える。【選択図】図1
