揭露人类流动性模式对于理解流行病,城市运输和其他体现空间和人类旅行的社会经济动态至关重要。根据志愿者的直接旅行日记,我们显示了单个级别的位移分布中没有缩放特性,而聚集的位移分布遵循具有指数截止的功率定律。鉴于对总旅行成本的限制,可以在最大熵的原则下通过人类旅行的混合性质在分析上预测这种汇总缩放定律。这种理论的直接推论是,单个运输方式的位移分布应遵循指数定律,该定律也获得了已知数据的支持证据。因此,我们得出的结论是,旅行成本塑造了汇总水平的位移分布。
Uncovering human mobility patterns is of fundamental importance to the understanding of epidemic spreading, urban transportation and other socioeconomic dynamics embodying spatiality and human travel. According to the direct travel diaries of volunteers, we show the absence of scaling properties in the displacement distribution at the individual level,while the aggregated displacement distribution follows a power law with an exponential cutoff. Given the constraint on total travelling cost, this aggregated scaling law can be analytically predicted by the mixture nature of human travel under the principle of maximum entropy. A direct corollary of such theory is that the displacement distribution of a single mode of transportation should follow an exponential law, which also gets supportive evidences in known data. We thus conclude that the travelling cost shapes the displacement distribution at the aggregated level.
