| 摘 要： | 根据网络交通拥挤的特征,利用交通波理论研究了交通拥堵形成的临界条件.首先分析了单车道信号控制路段的交通波传播特性,建立了过饱和形成的临界条件.然后针对基本路段拓扑结构特征,将基本路段分解为一系列单车道路段,在此基础上研究了复杂条件下交通波传播规律,并考虑了3种复杂因素,建立了相应的交通拥挤形成临界条件,包括不足的绿信比...

| Abstract: | Traffic wave theory is used to study the critical conditions for traffic jams according to their features. First, the characteristics of traffic wave propagation is analyzed for the simple signal-controlled lane and the critical conditions for oversaturation is established. Then, the basic road is decomposed into a series of one-way links according to its topological characteristics. Based on the decomposition, traffic wave propagation under complex conditions is studied. Three complicated factors are consi... |
