Unified-Evaluation-Driven RA-ALA for Three-Dimensional UAV Path Planning in Time-Varying Urban Low-Altitude Environments
Urban low-altitude unmanned aerial vehicle (UAV) planning is inherently spatiotemporal because route feasibility and cost depend on segment arrival times. Search-stage surrogates may therefore favor paths that fail execution-level checks as moving obstacles, temporary no-fly zones, wind-dependent energy use, and buildi...
