摘要
本文以通行能力变化为基本点,通过层次分析法、控制变量法、迭代法、元胞自动机思想、VISSIM仿真等方法,建立相应的数学模型。将小区开放对道路通行的影响分为直道通行能力、交叉口通行能力和道路情况三大指标,最后得到的交通能力影响因数为(0.2072,0.2572,0.2572,0.1531,0.1253)。考虑小区开放与小区结构、周边道路结构、车流量之间的关系,研究小区结构采用路网连接度和车辆饱和度的指标,将数据代入六指标体系,得到两种小区结构开放对道路通行能力的影响分别为0.1848,0.2043;得到结论:十字路口越多,交叉口总的交通能力越强,小区越需要开放。
In this paper, the capacity changes as the basic point, method and variable control method, iterative method, cellular automaton thought, VISSIM simulation by means of AHP, the corresponding mathematical model is established. The open area impact on road traffic is divided into straight road capacity and traffic capacity of the intersection and road three index effects the final factor is the traffic capacity(0.2072, 0.2572, 0.2572, 0.1531, 0.1253).Consider the relationship between residential and open cell structure and the surrounding road structure and traffic flow, the research on community structure using network connectivity and vehicle saturation index, the data into the six index system, get the effect of two kinds of open cell structure on the road capacity were 0.1848, 0.2043; conclusion: the total intersection crossroads more. The traffic capacity is higher,more community needs to open.
