Application Summary AI generated

This standard defines a classification system for pre-warning levels of highway traffic conditions specifically during snow and icy weather. It is applied by Chinese transportation authorities and highway management agencies to assess road surface conditions, visibility, and traffic risks, enabling them to issue graded alerts (e.g., red, orange, yellow) to guide traffic control measures and driver warnings. The standard supports operational decision-making for road maintenance, emergency response, and public safety communication in cold-region highway networks.
