VRE: A Versatile, Robust, and Economical Trajectory Data System

Summary: VRE uses a segment-based storage that blends point- and trajectory-based models, decoupling storage from processing to support multiple schemas. Unified pruning for five distance measures plus a two-stage pushdown processing framework with a secondary index delivers strong trajectory query efficiency and up to 3x storage reduction.
