Predicting the density and flow of the crowd at a citywide level is significant for emergency management, traffic regulation, and urban planning. By meshing a large urban area to a number of fine-grained mesh-grids, citywide crowd and traffic information in a continuous time period can be represented with 4D tensor (Timestep, Height, Width, Channel). Based on this, we revisit the density and in-out flow prediction problem and publish a new aggregated human mobility dataset generated from a real-world smartphone application. Compared with the existing ones, our dataset has larger mesh-grid number, finer-grained mesh size, and higher user sample. Towards such kind of largescale crowd dataset, we propose a novel deep learning model called DeepCrowd by designing pyramid architectures and highdimensional attention mechanism based on Convolutional LSTM. Both the datasets and codes are made available at https://github. com/deepkashiwa20/DeepCrowd.
