Multiday GPS tracking data of Shanghai

During the five-month surveying period, 459 individuals are recruited either on site or via Internet, more than 17 million GPS tracking points over 3,766 days are obtained. A total of 318 respondents’ socio-economic attributes, demographic information, and frequently visited locations are also collected via web-based survey. Among them, 267 volunteers completed more than 5 days of continuous smartphone-based GPS tracking, and participated in the PR survey to provide activity chain information corresponding to the GPS data. After necessary data preprocessing processes, such as the basic data cleaning, the activity chain nodes identification, the activity chain nodes attributes recognition, etc., a total of 10,407 activities/trips in 1,498 days are remained in the current dataset.在为期五个月的调研周期内，研究团队通过现场招募与互联网招募两种渠道，共征集到459名受访者，累计获取超过1700万个GPS追踪点位，总有效追踪时长超过3766天。同时，通过线上问卷调查，收集了全部318名受访者的社会经济属性、人口统计学信息及高频到访地点数据。其中267名志愿者完成了连续5天以上的基于智能手机的GPS追踪工作，并参与了PR调研，提供了与GPS数据匹配的活动链信息。经基础数据清洗、活动链节点识别、活动链节点属性识别等必要的数据预处理流程后，当前数据集最终保留了1498天内的10407条活动/出行记录。
