基于中关村南大街车流量的描述统计分析

Descriptive Statistical Analysis of Zhongguancun Street's Vehicle Flow

本文基于中关村南大街魏公村路口、大慧寺路口、万寿寺路口全天六个时段车流量基本数据,以魏公村路口为例,利用SPSS和EXCEL软件进行了描述性分析,以此说明魏公村路口的车流规律,再结合另外两个路口的分析结果,得到中关村南大街交叉口的交通特性.研究结果表明,中关村南大街全天车流量最高峰时段为17:30-18:30,最低峰时段为20:00-21:00,南北车流量大,东西车流量小,私车成为拥堵问题的罪魁祸首.研究结果可以为有关部门解决中关村南大街拥堵问题提供理论依据.

In this paper,based on the data of traffic volume of the Weigongcun Crossing,Dahuisi Crossing,and Wanshousi Crossing on the Zhongguancun Street in the six periods of one day,we take the Weigongcun Crossing as an example to reveal the change law of the traffic volume of the Weigongcun Crossing by the descriptive analysis technology using the SPSS software and EXCEL software.Then we combine the results with the other two crossing's results to obtain the traffic characteristics of the crossings on the Zhongguancun Street.Finally,the results of this research suggest that,the highest peak of traffic volume on the Zhongguancun Street all day is the period from 17:30 to 18:30,the lowest one is the period from 20:00 to 21:00,and the south-north direction has most traffic volume against the east-west direction which has little volume,and the private cars become the chief offenders of the congestion problem.This research can be the theoretical basis for the solution,which is made by some departments,to deal with the congestion problem of the Zhongguancun Street.
