基于手机信令数据的昆山市职住分布与通勤特征分析

Analysis on the Job-housing Spatial Distribution and Commuting Characteristics of Kunshan City Based on Cellular Signaling Data

城市交通问题愈发严峻,利用手机数据探究职住分布及通勤特征分析符合智慧城市和"四个交通"中智慧交通的发展理念,对推动交通运输现代化发展有着重要意义。当前,手机信令研究主要集中在职住空间识别方面,而对识别出来的职住状况背后的原因以及通勤等方面缺乏系统研究。本文以昆山市为研究对象,基于手机信令数据提取用户职住地信息,分析其职住空间分布特点,并在此基础上分析昆山市职住空间分布和通勤交通现状。

Urban traffic problems are increasingly severe. Using mobile phone data to explore the distribution of occupational residence and the analysis of commuting characteristics conforms to the concept of smart cities and smart traffic in "four traffic" development, and it is of great significance to promote the modernization of transportation the city. At present, research on cell-phone signaling mainly focuses on the recognition of the occupational and residential space. However, there is a lack of systematic research on the reasons behind this situation and commuting. This paper takes Kunshan city as the research object, extracts the user's residence and residence information based on the mobile phone signalling data, and analyzes the spatial distribution characteristics of their job and residence. Based on this analysis, the status of the spatial distribution of residence and commuting traffic in Kunshan city was analyzed.
