Taxis equipped with GPS localizers serve the transportation needs of a large number of people driven by diverse needs; their traces can tell us where passengers were picked up and dropped off, which route was taken, and what steps the driver took to find a new passenger. In this article, we provide an exhaustive survey of the work on mining these traces. We first provide a formalization of the data sets, along with an overview of different mechanisms for preprocessing the data. We then classify the existing work into three main categories: social dynamics, traffic dynamics and operational dynamics. Social dynamics refers to the study of the collective behaviour of a city\u2019s population, based on their observed movements; Traffic dynamics studies the resulting flow of the movement through the road network; Operational dynamics refers to the study and analysis of taxi driver\u2019s<jats:italic>modus operandi<\/jats:italic>. We discuss the different problems currently being researched, the various approaches proposed, and suggest new avenues of research. Finally, we present a historical overview of the research work in this field and discuss which areas hold most promise for future research.<\/jats:p>","DOI":"10.1145\/2543581.2543584","type":"journal-article","created":{"date-parts":[[2014,1,6]],"date-time":"2014-01-06T20:42:39Z","timestamp":1389040959000},"page":"1-34","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":216,"title":["From taxi GPS traces to social and community dynamics"],"prefix":"10.1145","volume":"46","author":[{"given":"Pablo Samuel","family":"Castro","sequence":"first","affiliation":[{"name":"Institut Mines-TELECOM\/TELECOM SudParis; 9, rue Charles Fourier; 91011 Evry Cedex, France"}]},{"given":"Daqing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institut Mines-TELECOM\/TELECOM SudParis; 9, rue Charles Fourier; 91011 Evry Cedex, France"}]},{"given":"Chao","family":"Chen","sequence":"additional","affiliation":[{"name":"Institut Mines-TELECOM\/TELECOM SudParis; 9, rue Charles Fourier; 91011 Evry Cedex, France; and Universite Pierre et Marie Curie; 4, place Jussieu; 75005 Paris, France"}]},{"given":"Shijian","family":"Li","sequence":"additional","affiliation":[{"name":"Zhejiang University; Hangzhou, 310027, P.R.
