Review & Perspective for Distance Based Clustering of Vehicle Trajectories
Résumé
—In this paper we tackle the issue of clustering trajectories of geolocalized observations based on distance between trajectories. We first provide a comprehensive review of the different distances used in the literature to compare trajectories. Then based on the limitations of these methods, we introduce a new distance: Symmetrized Segment-Path Distance (SSPD). We compare this new distance to the others according to their corresponding clustering results obtained using both the hierarchical clustering and affinity propagation methods. We finally present a python package : trajectory distance, which contains the methods for calculating the SSPD distance and the other distances reviewed in this paper.
