基于生灭过程的城市道路通行能力研究

Capacity Study of Urban Road Based on Birth and Death Processes

摘要: 首先利用折线图和拟合分析，研究了车道被占用时道路通行能力的变化过程，接着利用交通流模型定量地分析了不同车道被占用道路通行能力的差异，然后对车辆到达率进行了K-S检验，结果显示符合泊松分布，最后利用生灭过程建立车辆排队长度、排队时间和道路通行能力的关系模型。

Abstract: Firstly, the changing process of the road traffic capacity is studied by using the Line Graph and the Fitting analysis. Then, the Q-V-K model is used to quantitatively analyze the difference of the capacity of the road when different lanes are occupied. In addition, the vehicle arrival rate was tested by K-S test, and the results show that it obeys the Poisson distribution. At last, the model of the relationship among vehicle queue length, queuing time and road traffic capacity is established by using the Birth and Death process.
