    • A central device 4 includes: a measurement processing unit 410 that acquires an inflow traffic volume at a first intersection Ci-1; an estimation processing unit 411 that estimates an inflow traffic volume at a second intersection Ci-2 on the basis of at least one of the inflow traffic volume at the first intersection Ci-1 and probe data obtained from a traveling vehicle 5; a control processing unit 412 that generates signal control parameters for the first intersection Ci-1 on the basis of the inflow traffic volume at the first intersection Ci-1, and generates signal control parameters 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 that transmits the generated signal control parameters for the first intersection Ci-1 to a traffic signal controller 1a at the first intersection Ci-1, and transmits the generated signal control parameters for the second intersection Ci-2 to a traffic signal controller 1a at the second intersection Ci-2.
    • 中央设备4包括:测量处理单元410,其获取第一交点Ci-1处的入流业务量; 估计处理单元411,其基于第一交点Ci-1的流入交通量和从行驶车辆5得到的探测数据中的至少一个来估计第二交叉口Ci-2处的流入交通量; 控制处理单元412,其基于第一交点Ci-1处的流入流量生成用于第一交点Ci-1的信号控制参数,并且基于第一交叉点Ci-1生成用于第二交叉点Ci-2的信号控制参数 第二个交点Ci-2的估计入流量; 以及通信单元403,其将生成的第一交点Ci-1的信号控制参数发送到第一交点Ci-1处的交通信号控制器1a,并将生成的第二交点Ci-2的信号控制参数发送到交通 信号控制器1a在第二交点Ci-2处。
