摘要:

识别海量手机数据中蕴含的行为模式,是地理学的一个研究热点与难点。目前,较多研究针对手机用户移动特征开展,而对停留及其模式的研究则相对较少;其时空分异规律对理解城市人群动态,甚至优化城市系统至关重要。本文根据人们日常时空约束条件定义了手机用户停留,提出了基于海量手机位置数据的手机用户停留模式的提取方法,以深圳市约790万个匿名手机用户一天的海量手机位置数据为例,识别出了覆盖约98%用户的典型停留模式,并结合该城市土地利用的空间分布与分异特征,剖析不同停留模式的手机用户空间分异特征和城市不同区域停留次数的时段分异特征。研究发现:(1)15种停留模式可覆盖约98%的手机用户,而且其一天不同的停留位置数量不超过4个;(2)15种停留模式手机用户在城市区域空间上的分布存在分异现象,严重受制于土地利用的空间分布;(3)城市不同区域停留次数的时段分异特征与该区域常住人口、人口密度,以及区域主要职能和性质存在较强的相关性。研究结论对理解城市手机用户行为模式的群体特征有积极的意义,对城市土地利用的科学决策和城市交通规划与预测有重要参考价值。

Abstract:

Identifying human behavior patterns embedded in massive mobile phone data records is a research hotspot and difficulty of study in geography. While lots of researches are aiming at investigation of the mobility characteristics of mobile phone users, studies focusing on the stay of mobile phone users and their stay patterns are relatively little. The spatio-temporal heterogeneous regularity is vital for understanding the urban human dynamic and optimizing urban system. Therefore, this paper explored the stay patterns of mobile phone users in order to understand the human mobility patterns and their features. According to the spatial and temporal constraints of human routine and travel behavior, this paper defined the stay conditions and the stay patterns of urban mobile phone users, and come up with methods of identifying and extracting stay patterns from massive mobile phone data records. Then, we took about 7.9 million mobile phone users’ one day data records in Shenzhen City in China as an example, processed them with the designed method, and identified some typical stay patterns which covered about 98% of the urban mobile phone users. In addition, we conducted statistical analysis for urban mobile phone users’ stay patterns and analyzed their spatial distribution with respect to different administrative districts combining with the city’s land use pattern. Furthermore, we dissected the heterogeneous characteristics of the spatial distribution of different stay pattern’s users and the stay frequencies against different administrative districts over a 22-hour period. The study shows: (1) 15 types of stay patterns can cover 98% urban mobile phone users’ behavior and their stay locations are no more than 4 in one day. The stay patterns with 2 stay locations shows the highest probability that nearly half of the mobile phone users have this tendency. (2) The spatial distribution of the 15 stay patterns in the city is evidently heterogeneous, which is subjected to the urban land use. We found that the higher proportion of leisure and entertainment land in a certain administrative district, the stay patterns with more stay locations in this region are likely to occur. (3) The heterogeneity of the stay frequency for different urban administrative district is strongly related to its permanent resident population, population density and major function of the district. The study conclusions are useful in understanding the population characteristics of urban phone users’ behavior, the activity patterns and urban residents’ commuting behavior. Moreover, it can provide important references for scientific decisions of urban land use, urban transportation planning and prediction.
