The near-real-time prediction of urban populations at the fine-grained scales can provide an important scientific basis in many fields, such as optimizing the allocation of public resources, assisting urban traffic guidance, making the early warning in urban emergencies, as well as exploring daily life patterns of urban residents. In this study, based on time series analysis method, a parameter prediction model (i.e., the Autoregressive Integrated Moving Average model) and a non-parameter prediction model (i.e., the K-Nearest Neighboring model) are constructed to predict urban populations in large spatial and temporal scales. The spatial resolution is 0.005 arc-degree and the temporal resolution is 30 minutes. When applying these two prediction models to a large mobile phone location dataset, the results demonstrate that both of them can be helpful to the near-real-time prediction of urban populations. In particular, the non-parameter prediction model produced more stable prediction results with lower error than the parameter prediction model, from the perspectives of prediction error distributions by grid population, prediction error distributions in space and time, prediction error at different temporal granularities, and prediction error distributions under a special event.
