标题： Mapping mobile service usage diversity in cities

摘要： 移动设备和相关互联网服务的普遍使用产生了大量地理定位数据，为理解人类行为及其与城市环境的互动提供了有价值的见解。 在过去十年中，手机数据在人口统计学、地理学、交通规划和流行病学等多个领域已被证明是不可或缺的。 它们使研究人员能够以前所未有的规模检查人类移动模式，并分析城市的空间结构和功能。 手机数据与土地利用之间的关系也得到了广泛研究，特别是在从时空活动推断土地利用模式方面。 然而，许多研究依赖于通话详单（CDR）或扩展详单（XDR），这些数据可能无法捕捉特定移动应用的使用情况。 本研究旨在通过绘制20个法国城市中的移动服务使用多样性，并研究其与土地利用分布的相关性来弥补这一空白。 利用香农多样性指数，该研究基于17种移动服务的每小时流量数据评估移动服务使用多样性。 此外，该研究还比较了城市内部及城市之间的时间多样性与土地分布。 显示英文摘要

摘要： The ubiquitous use of mobile devices and associated Internet services generates vast volumes of geolocated data, offering valuable insights into human behaviors and their interactions with urban environments. Over the past decade, mobile phone data have proven indispensable in various fields such as demography, geography, transport planning, and epidemiology. They enable researchers to examine human mobility patterns on unprecedented scales and analyze the spatial structure and function of cities. The relationship between mobile phone data and land use has also been extensively explored, particularly in inferring land use patterns from spatiotemporal activity. However, many studies rely on Call Detail Records (CDR) or eXtended Detail Records (XDR), which may not capture specific mobile application usage. This study aims to address this gap by mapping mobile service usage diversity in 20 French cities and investigating its correlation with land use distribution. Utilizing a Shannon diversity index, the study evaluates mobile service usage diversity based on hourly traffic volume data from 17 mobile services. Furthermore, the study compares temporal diversity with land distribution both within and among cities.
