The invention provides an intelligent traffic Internet of Things system and method, and the method comprises the steps: determining a congestion index of each intersection through the traffic delay time and traffic saturation of each intersection in a traffic control region, and obtaining a plurality of key intersections through the extraction of each congestion index; constructing a hierarchical control structure of the traffic control area according to the road network topological graph of the traffic control area and the associated intersection corresponding to each key intersection; determining association parameters of traffic flow between adjacent control layers in the hierarchical control structure, and performing traffic signal coordination analysis on each control layer according to all the association parameters in combination with the increasable capacity of the traffic flow in each control layer to obtain coordination signal timing of each control layer under the current traffic flow condition; and carrying out coordination control on traffic signals of intersections under each control layer according to all coordination signal timing. According to the scheme, global traffic flow control of the traffic control area can be realized based on coordination signal timing.

    本申请提供了一种智能交通物联网系统及方法,通过交通管控区域内每个交叉路口处的交通延误时间和交通饱和度确定每个交叉路口的拥堵指数,通过各个拥堵指数提取得到多个关键交叉口;依据交通管控区域的路网拓扑图和每个关键交叉口对应的关联交叉口构建交通管控区域的分层控制结构;确定分层控制结构中相邻控制层之间车流的关联参数,根据所有的关联参数结合每个控制层中车流的可增容量对每个控制层进行交通信号的协调分析,得到每个控制层在当前车流量条件下的协调信号配时;依据所有的协调信号配时对各个控制层下交叉路口的交通信号进行协调控制。上述方案基于协调信号配时,可实现对交通管控区域的全局车流控制。
