China Readies L4 Autonomous Bus Pilot in Suzhou as CRRC-Tiantong Partnership Brings Self‑Driving Tech into Public Transit

TianTong Weishi and China CRRC plan to deploy Level‑4 autonomous buses in Suzhou’s Taihu New City in Q1 2026, linking a university campus to Metro Line 7. The pilot is a contained, strategic test of driverless public transit that could inform safety rules, urban planning and commercial rollouts if it proves reliable under real‑world conditions.
