讲座题目：Mobility and Activity Space: Understanding Human Dynamics from Mobile Phone Location Data
讲座内容：Studying human mobility patterns and people’s use of space has been a major focus in geographic research for ages. Recent advancements of location-aware technologies have produced large collections of individual tracking datasets. Mobile phone location data, as one of the many emerging data sources, provide new opportunities to understand how people move around at a relatively low cost and unprecedented scale. However, the increasing data volume, issue of data sparsity, and lack of supplementary information introduce additional challenges when such data are used for human behavioral research. Effective analytical methods are needed to meet the challenges to gain an improved understanding of individual mobility and collective behavioral patterns. This presentation will discuss how large-scale mobile phone location data (Call Detail Records and Actively Tracked Mobile Phone Data) can be leveraged to better understand important characteristics of human activity space, the implications in urban and transportation planning, and their limitations in human dynamics research.
报告人简介：
Yang Xu received a Bachelor of Science degree in Remote Sensing and Photogrammetry at Wuhan University in 2009, and a Master of Science degree in Geographic Information System in 2011. After graduation, he joined the Department of Geography at the University of Tennessee, Knoxville (UTK), where he earned his Ph.D. in December 2015.
Yang Xu’s research interests include geographic information science (GIScience), transportation GIS, and spatial-temporal data mining. During 2013 and 2015, he participated in several interdisciplinary research projects at Oak Ridge National Laboratory (ORNL) to tackle a wide array of environmental science problems using advanced software engineering approaches. During his Ph.D. period, he delivered many publications in peer-reviewed journals (e.g., Transportation, Annals of the American Association of Geographers, International Journal of Geographic Information Science, Environmental Modelling & Software, and Journal of Computational Science) and conference proceedings (GIScience, GeoComputation). He received an Exceptional Professional Accomplishment Award in the Geography Department at UTK in 2015. Yang Xu will join the Senseable City Lab at Massachusetts Institute of Technology (MIT) in June, 2016.
