Clustering of Vehicle Trajectories

IEEE Transactions on Intelligent Transportation Systems, 2010
We present a method that is suitable for clustering of vehicle trajectories obtained by an automated vision system. We combine ideas from two spectral clustering methods and propose a trajectory-similarity measure based on the Hausdorff distance, with modifications to improve its robustness and account for the fact that trajectories are ordered ...

Spatiotemporal Trajectory Clustering: A Clustering Algorithm for Spatiotemporal Data

Expert Systems With Applications, 2021
Abstract Spatial technologies generate large datasets quickly and continuously. The purpose of this study is to develop a clustering algorithm to mine spatiotemporal co-location events in trajectory datasets. We present a spatiotemporal algorithm for sub-trajectory clustering that divides a trajectory into line segments and groups theses sub ...
