受益于最近飞速发展的信息技术,特别是手机和汽车上的GPS,我们可以直接或间接获得大量人类移动轨迹数据,这给了研究人员一个前所未有的了解大规模群体复杂空间行为的机会。研究人类空间移动规律对于防止和控制疾病传播、预测和控制交通流量、监测有拥挤踩踏风险的大规模高密度人群聚集、对人口迁移行为的宏观理解等方面,都有基础性的价值。
Benefiting from the recent rapid advances in information technology, especially GPS on mobile phones and cars, we have access to a large amount of human trajectories, either directly or indirectly, giving researchers an unprecedented opportunity to understand the complex behavior of large groups. Studying the law of spatial movement of human beings is of fundamental value in preventing and controlling disease transmission, predicting and controlling traffic flow, monitoring the accumulation of large-scale and high-density crowd with the risk of crowded stampeding, and macroscopic understanding of population migration.
