Lane‑Level Navigation Simulation: Road Scene Strategy Engine and Vehicle‑Behavior Modeling

Amap’s lane‑level navigation simulation combines a road‑scene strategy engine—using modified ant‑colony optimization to efficiently cover national and city road networks—with a vehicle‑behavior engine that plans lane‑change paths via Dijkstra and models realistic speed profiles through reaction and curvature intervals, enabling custom high‑precision testing while cutting road‑test costs.
