The correlation between human mobility and socio-demographic in megacity

摘要

Understanding human mobility is of great importance for various applications, such as urban planning and traffic forecasting. In this paper, we explore the correlation between human mobility and socio-demographic characteristics through two massive datasets containing individuals' attributes and daily GPS trajectory information respectively. Individuals' daily trajectories, trip displacement and daily radius of gyration are further studied. The results confirm that the distribution of daily radius of gyration is power law. It is found that women travels longer and further to their center of mass than man. The employed stay closer to their center of mass while their displacement is larger. Besides, it is surprising to find that under foggy days, trip displacement and radius of gyration are much bigger than that of other weather conditions.
