对人类流动模式的研究具有多方面的理论和实践价值。对于长途旅行，一些研究表明，人类旅行的位移服从幂函数分布。然而，关于城市内部地区人口流动的尺度规律问题，仍然存在争议。在这项工作中，我们通过检验三个大都市的五个数据集来研究出租车乘客的流动模式。通过统计分析，我们发现具有幂函数尾部的对数正态分布能够最好地逼近所有被调查城市的出租车出行量和持续时间。随后，根据对数据的分析，讨论了人类流动性标度律的普适性。选定的涵盖不同城市和研究时期的数据集的统计特性的一致性表明，已确定的出租车市内出行模式似乎在城市和时期内无处不在。
The study of human mobility patterns is of both theoretical and practical values in many aspects. For long-distance travel, a few research endeavors have shown that the displacements of human travels follow a power-law distribution. However, controversies remain regarding the issue of the scaling laws of human mobility in intra-urban areas. In this work, we focus on the mobility pattern of taxi passengers by examining five datasets of three metropolitans. Through statistical analysis, we find that the lognormal distribution with a power-law tail can best approximate both the displacement and the duration time of taxi trips in all the examined cities. The universality of the scaling laws of human mobility is subsequently discussed, in view of the analysis of the data. The consistency of the statistical properties of the selected datasets that cover different cities and study periods suggests that, the identified pattern of taxi-based intra-urban travels seems to be ubiquitous over cities and time periods.
