For corridor retiming, I’ll nail splits/offsets in Synchro, then only move to VISSIM if queues are flirting with turn pockets — carry over the exact same saturation flows, lost times, and detector logic so actuated‑coordinated behaves consistently. If time’s tight, do a 30–45 min Bluetooth travel‑time run to ground‑truth Synchro before microsim; FHWA’s Signal Timing Manual has a solid checklist: https://ops.fhwa.dot.gov/publications/fhwahop16019/index.htm.
