基于交通流元胞自动机模型的小区开放问题研究

Research on Community Opening Based on Traffic Flow Cellular Automata Model

本文以小区开放问题为实际研究背景,建立基于微观交通流元胞自动机模型的车辆通行能力模型。利用NaSch模型进行小区开放问题的数值模拟,分析了不同预设参数下小区开放对交通平均速度和流量的影响。选取河南省郑州市的紫云小区和响水湾小区作为分析实例,对模型进行分析验证。分析表明:小区开放对周边局部交通拥堵的缓解作用不是绝对的,需要通过对小区和周边环境具体交通参数做综合分析才能得到结论。

In this paper, a vehicle capacity model based on micro-traffic flow cellular automata model is es-tablished based on the practical research background of community opening problem. The NaSch model is used to simulate the opening problem of a small area, and the influence of opening of a small area on the average speed and flow of traffic under different preset parameters is analyzed. Ziyun and Xiangshuiwan communities in Zhengzhou, Henan province are selected as examples to verify the model. The analysis shows that the easing effect of community opening on local traffic congestion in the surrounding area is not absolute, and the conclusion can only be reached through comprehensive analysis of specific traffic parameters of the community and the surrounding environment.
