Understanding human mobility patterns—how people move in their everyday lives—is an interdisciplinary research field. It is a question with roots back to the 19th century that has been dramatically revitalized with the recent increase in data availability. Models of human mobility often take the population distribution as a starting point. Another, sometimes more accurate, data source is land-use maps. In this paper, we discuss how the intra-city movement patterns, and consequently population distribution, can be predicted from such data sources. As a link between land use and mobility, we show that the purposes of people's trips are strongly correlated with the land use of the trip's origin and destination. We calibrate, validate and discuss our model using survey data.
理解人类移动模式——即人们在日常生活中的移动方式——是一个跨学科研究领域。这是一个可追溯到19世纪的问题,随着近期数据可得性的增加而得到了极大的复兴。人类移动模型通常以人口分布为起点。另一个有时更准确的数据来源是土地利用地图。在本文中,我们讨论了如何从这些数据源预测城市内部的移动模式以及由此产生的人口分布。作为土地利用与移动性之间的联系,我们表明人们出行的目的与出行起点和终点的土地利用密切相关。我们使用调查数据对我们的模型进行校准、验证和讨论。
