摘要:

在不同的空间尺度上预测人类流动流动的挑战是个人轨迹的异质性和交通网络的多尺度性质。随着人类行为的大量数字痕迹变得可用,通过将各种数字平台和位置感知服务收集的关于移动性的代理数据整合到其中来改进移动模型的机会出现了。在这里,我们提出了一个混合模型的人的流动性,集成了一个大规模的公开可用的数据集,从一个流行的照片共享系统与经典的重力模型,在堆栈回归过程。我们使用美国航空旅行和日常通勤的两个地面实况数据集来验证我们方法的性能和可推广性:使用两种不同的交叉验证方案,我们表明混合模型在两个空间尺度上都提供了增强的移动性预测。

英文摘要:

Predicting human mobility flows at different spatial scales is challenged by the heterogeneity of individual trajectories and the multi-scale nature of transportation networks. As vast amounts of digital traces of human behaviour become available, an opportunity arises to improve mobility models by integrating into them proxy data on mobility collected by a variety of digital platforms and location-aware services. Here we propose a hybrid model of human mobility that integrates a large-scale publicly available dataset from a popular photo-sharing system with the classical gravity model, under a stacked regression procedure. We validate the performance and generalizability of our approach using two ground-truth datasets on air travel and daily commuting in the United States: using two different cross-validation schemes we show that the hybrid model affords enhanced mobility prediction at both spatial scales.
