摘要: 针对城市道路中公交进出直线式停靠站对路段车流延误产生影响的问题,运用车流波动理论相关成果,分别建立无信号交叉口影响、绿灯时间内消散、一周期内消散和一周期内无法消散4种情况下交通流延误模型。结果表明:在信号控制交叉口的影响下,交叉口下游机动车交通流量波动表现近似周期性的特征,公交停靠站影响区域内车辆纵向偏移呈现压缩、膨胀、扩散三个状态,出现压缩膨胀波,存在车流的波动现象。该模型的具有较高的精度和可靠性,能够为城市道路管理和设计提供必要的参考依据。

Abstract: To enhance the utilizing efficiency and accessibility of curb-lane bus stop and minimize the im-pacts on dynamic traffic flow, the traffic delay models based on traffic flow wave theory were proposed by investigating and analyzing four curb-lane bus stops in Nanjing. Those models were used to describe traffic delay in the condition of no-signalized intersections flow, dissipated flow in green times, dissipated flow in a signal cycle and interacted flow in next signal cycle. Practical example of vehicle arrive shows that the vehi-cle arriving characteristic is continuous and interacted on urban roadway affected by signalized intersection flow. A compressional dilatational wave was found near curb-lane bus stop, which has three states of con-sciousness, expandability and dissipation. The proposed approach can be applied to describe the delay of traf-fic delay effectively.
