description The invention relates to a spatio-temporal trajectory generation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring real urban trajectory data in a research area, and performing multi-spatial scale division and preprocessing on the urban trajectory data to generate a travel trajectory sequence; carrying out embedded representation and position coding on the travel track sequence, and extracting spatio-temporal information of the travel track sequence by adopting a Transform model; inputting the spatio-temporal information of the travel trajectory sequence into a generative adversarial network, and generating multi-scale spatio-temporal trajectory data through the generative adversarial network; wherein the multi-scale spatio-temporal trajectory data comprises spatio-temporal trajectory data of a street level and spatio-temporal trajectory data of a community level. According to the method and the device, the individual travel characteristics can be
