Query: VLUC: An Empirical Benchmark for Video-Like Urban Computing on Citywide
  Crowd and Traffic Prediction   Nowadays, massive urban human mobility data are being generated from mobile
phones, car navigation systems, and traffic sensors. Predicting the density and
flow of the crowd or traffic at a citywide level becomes possible by using the
big data and cutting-edge AI technologies. It has been a very significant
research topic with high social impact, which can be widely applied to
emergency management, traffic regulation, and urban planning. In particular, 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
like a video, where each timestamp can be seen as one video frame. Based on
this idea, a series of methods have been proposed to address video-like
prediction for citywide crowd and traffic. In this study, we publish a new
aggregated human mobility dataset generated from a real-world smartphone
application and build a standard benchmark for such kind of video-like urban
computing with this new dataset and the existing open datasets. We first
comprehensively review the state-of-the-art works of literature and formulate
the density and in-out flow prediction problem, then conduct a thorough
performance assessment for those methods. With this benchmark, we hope
researchers can easily follow up and quickly launch a new solution on this
topic.
