The field of urban spatial-temporal prediction is advancing rapidly with the
development of deep learning techniques and the availability of large-scale
datasets. However, challenges persist in accessing and utilizing diverse urban
spatial-temporal datasets from different sources and stored in different
formats, as well as determining effective model structures and components with
the proliferation of deep learning models. This work addresses these challenges
and provides three significant contributions. Firstly, we introduce "atomic
files", a unified storage format designed for urban spatial-temporal big data,
and validate its effectiveness on 40 diverse datasets, simplifying data
management. Secondly, we present a comprehensive overview of technological
advances in urban spatial-temporal prediction models, guiding the development
of robust models. Thirdly, we conduct extensive experiments using diverse
models and datasets, establishing a performance leaderboard and identifying
promising research directions. Overall, this work effectively manages urban
spatial-temporal data, guides future efforts, and facilitates the development
of accurate and efficient urban spatial-temporal prediction models. It can
potentially make long-term contributions to urban spatial-temporal data
management and prediction, ultimately leading to improved urban living
standards.
