Trajectory Simplification: An Experimental Study and Quality Analysis
Summary: Comprehensive benchmark of 25 trajectory-simplification algorithms across five datasets with diverse motion patterns. Goes beyond error metrics to assess reduced trajectories’ utility for spatio-temporal queries, deriving practical algorithm-selection guidance. (summarized by gpt-5.6-luna on Jul 24 2026)
