摘　　要：在单路口交通灯实时控制的基础上对城市道路多路口交通灯实时控制进行了研究。提出了一种双层次子区域的智能划分方法并应用于区域交通信号的实时控制,在子区域基础上建立多交叉口数学模型;运用指数平滑预测模型为BP神经网络模型提供学习所需数据,并将得到的混沌交通流序列与改进泊松函数得到的泊松分布断面发车随机数进行比较。通过上述模型及算法最终得到区域交通路口实时配时方案。Based on the real-time traffic, light control for a single intersection, the real-time traffic light control for urban road multi-intersection is researched. We present a two-tier regional intelligence division method and use it in regional real-time traffic signal control, and build multi-intersection mathematical model on the basis of the sub-regional; utilize exponential smoothing forecasting model to provide learning data required for BP neural network model, and compare the chaotic sequence of traffic flow obtained from it and the Poisson distributed random cross-section numbers obtained from the improved Poisson function. Through above model and algorithm, the real-time timing program for regional traffic road intersections is finally achieved.
