Abstract: The present invention discloses a human mobility prediction method based on a generative adversarial network. According to the method, the integration of spatio-temporal features of multimodal data is studied by virtue of studying urban human mobility prediction during the pandemic. A human mobility mode is difficult to be predicted during the pandemic due to complex multimodal data such as complicated social background, policy and pandemic situation. The analysis of human mobility data from three cities in China shows that different cities have highly similar human mobility modes during the pandemic, despite of great differences between them. On this basis, the disclosure designs a prediction model, in which the effects of the multimodal data on the spatio-temporal features of the human mobility are modeled integrally. In addition to this, the model can help the government evaluate the potential effects of different policies on human mobility better, and optimize policy development.
