Baidu mobility data for January through April, 2020

This archive contains mobility data made public by Baidu and scraped from their qiangxi.baidu.com web site in February, March, and April, 2020. We have reformatted the data into a more easily computable form, comma-separated value (csv) files providing the full origin-destination matrix for each day. We are publishing this reformatted version for research purposes under Article 22 of the Copyright Law of the People's Republic of China (https://wipolex.wipo.int/en/text/466268). We make no representation as to the suitability of the data for any purpose, but nevertheless hope that it may be useful for researchers trying to calibrate models of 2019-ncov. We wish to thank Baidu especially for making these valuable data available and encourage them to continue to do so. Thanks also to Chunhong Mao for making us aware of this data source and explaining what the data represent and to James Schlitt for scraping the data.本数据存档包含百度公开的人口流动数据集，该数据集于2020年2月、3月及4月从百度旗下qiangxi.baidu.com网站抓取获取。我们已将原始数据重新格式化为更便于计算的形式，即生成针对每日数据的完整起讫点（Origin-Destination Matrix, OD）矩阵的逗号分隔值（Comma-Separated Value, CSV）文件。我们依据《中华人民共和国著作权法》第二十二条（https://wipolex.wipo.int/en/text/466268），以学术研究为目的发布此经重新格式化的数据集版本。我们未就本数据适用于任何特定用途作出任何声明，但仍期望其可为试图校准2019新型冠状病毒（2019-nCoV）传播模型的研究人员提供助力。我们特别感谢百度提供这些宝贵数据，并鼓励其继续推出此类公开数据服务。此外感谢毛春红（Chunhong Mao）向我们介绍该数据源并解释数据含义，以及詹姆斯·施利特（James Schlitt）负责本次数据抓取工作。
