基于主成分分析法的小区开放对道路通行的影响问题的研究

随着我国经济飞速发展,以及人口增长和人们生活节奏的加快,城市路网交通日趋繁忙。而封闭性小区开放对周边道路交通通行有着重要影响。针对这一重要问题,本文运用主成分分析的方法,建立了以路网密度、道路面积率、车流量、行车速度、道路服务等级、路口饱和度、出入口连接方式为主要指标的指标体系,并主要针对两种不同类型的小区,基于MATLAB仿真,比较了开放前后周边道路的通行情况,最后就小区开放提出了合理化建议。

With the rapid development of China＇s economy, as well as population growth and the accelerated pace of people＇s life, urban road network traffic is getting busy. The closed area of the opening of the surrounding road traffic has an important impact. In view of this important problem, this paper uses the method of principal component analysis to establish the index system with road net- work density, road area ratio, traffic flow, driving speed, road service level, intersection saturation, import and export connection mode as the main index, and mainly for two different types of residential, based on MATLAB simulation, compared the road before and after the opening of the passage of the situation, and finally put forward the rationalization of the proposed district.
