TrajGraph: A Graph-Based Visual Analytics Approach to Studying Urban Network Centralities Using Taxi Trajectory Data

Xiaoke Huang, Ye Zhao, Chao Ma, Jing Yang, Xinyue Ye, Chong Zhang
2016 IEEE Transactions on Visualization and Computer Graphics  
We propose TrajGraph, a new visual analytics method, for studying urban mobility patterns by integrating graph modeling and visual analysis with taxi trajectory data.  ...  We also present several examples and a case study to demonstrate the usefulness of TrajGraph in urban transportation analysis.  ...  ACKNOWLEDGMENTS We would like to thank Shuo Zhao for his help in the user study with Shenzhen drivers.  ...
