Smart highway vehicle–road coordination is shifting from demonstration-based validation toward industrial operation, yet its commercialization remains constrained by inadequate pilot-scale testing, unclear data authorization, weak interface coordination, insufficient traceability in acceptance procedures, and incomplete revenue realization mechanisms. Drawing on cases such as the vehicle–road–cloud integration pilot program, the Beijing High-Level Automated Driving Demonstration Area, and the Wuxi Internet of Vehicles Pilot Zone, this study proposes a data governance pathway that connects research outcomes, project delivery, and continuous services through scenario screening, engineering scale-up, service packaging, compliance acceptance, and operational review.
