PROBLEM TO BE SOLVED: To increase the efficiency of traffic processing in the entire area to be controlled.SOLUTION: A central device 4 comprises: a measurement processing unit 410 for acquiring an inflow traffic volume at a first intersection Ci-1; an estimation processing unit 411 for estimating an inflow traffic volume at a second intersection Ci-2 on the basis of the inflow traffic volume at the first intersection Ci-1 and/or probe the information obtained from a vehicle 5; a control processing unit 412 for generating a signal control parameter for the first intersection Ci-1 on the basis of the inflow traffic volume at the first intersection Ci-1, and generating a signal control parameter for the second intersection Ci-2 on the basis of the estimated inflow traffic volume at the second intersection Ci-2; and a communication unit 403 for transmitting the generated signal control parameter for the first intersection Ci-1 to the traffic signal controller 1a of the first intersection Ci-1, and transmitting the generated signal control parameter for the second intersection Ci-2 to the traffic signal controller 1a of the second intersection Ci-2.

    【課題】 制御すべきエリア全体における交通処理の効率化を図る。【解決手段】 中央装置4は、第1交差点Ci−1の流入交通量を取得する計測処理部410と、第1交差点Ci−1の流入交通量と、車両5から得られるプローブ情報のうちの少なくも一方に基づいて第2交差点Ci−2の流入交通量を推定する推定処理部411と、第1交差点Ci−1の流入交通量に基づいて、第1交差点Ci−1の信号制御パラメータを生成し、第2交差点Ci−2の推定流入交通量に基づいて、第2交差点Ci−2の信号制御パラメータを生成する制御処理部412と、生成した第1交差点Ci−1の信号制御パラメータを当該第1交差点Ci−1の交通信号制御機1aに送信し、生成した第2交差点Ci−2の信号制御パラメータを当該第2交差点Ci−2の交通信号制御機1aに送信する通信部403とを備えている。【選択図】 図4
