基于主成分综合评价的小区开放对周边道路通行能力影响的研究

The Study on the Influence of Community Opening on the Traffic Capacity of Surrounding Roads based on the Comprehensive Evaluation of Principal Components

近年来,城市"堵车"现象愈发严重.开放式小区可以保持小区内道路与外界道路连通,起到优化道路网络结构、疏通城市"毛细血管"的作用.为了评价小区开放后对邻边交通状况的影响,文章从3大方面找出5个相关指标,构建了影响小区开放前后邻边主干道通行能力的指标体系.通过建立主成分综合评价模型,利用SPSS数学软件进行主成分分析与求解,并分别给出交通管理部门和城市规划部门共计7条建议.

In recent years,the phenomenon of"traffic jam"in Chinese cities is becoming more and more serious.The open community can optimize the road network structure,and dredging the function of the city"capillaries".This paper builds an indicator system to describe the influence of community opening on the traffic capacity of surrounding roads as well as establish a principal component comprehensive evaluation model and use SPSS mathematical software to analyze and solve the model.
