An Extended Exploration and Preferential Return Model for Human Mobility Simulation at Individual and Collective Levels

Human mobility models have prevalent applications in traffic management, urban planning, and disease prevention. Modeling human mobility combining both the statistical physical mechanics and geographical constrains is not fully investigated. In this …

Quantifying the Scale Effect in Geospatial Big Data Using Semi-Variograms

The scale effect is an important research topic in the field of geography. When aggregating individual-level data into areal units, encountering the scale problem is inevitable. This problem is more substantial when mining collective patterns from …

Inferring Demographics from Human Trajectories and Geographical Context

The advances of positioning technologies and the widespread use of mobile devices bring us massive data with location information, or so-called big geo-data. One important part of big geo-data is massive digital human trajectories recorded by …

Measuring Spatio-Temporal Autocorrelation in Time Series Data of Collective Human Mobility

Massive spatio-temporal big data about human mobility have become increasingly available. Revealing underlying dynamic patterns from these data is essential for understanding people's behavior and urban deployment. Spatio-temporal autocorrelation …
