A comparative analysis of trajectory similarity measures
Overview
Paper Summary
The study found that the choice of similarity measure can significantly impact the results of trajectory analysis. Spatial differences between trajectories were found to be more influential than temporal differences in determining similarity. The paper provides recommendations for selecting and using trajectory similarity measures in practice.
Explain Like I'm Five
This is like when you track two friends walking. Scientists found that to see how similar their walks were, it's more important to look at the exact path they took on the ground than exactly what time they were at each spot.
