In order to mitigate the impacts of adverse weather on transportation mobility, traffic safety, management, and maintenance productivity, the idea of constructing an Expressway Safety Management System (ESMS) that is concerned more with the safety management demand, especially in cases of adverse weather, was put forward in this paper. The author indicated the construction concept, architecture, major functions, and sub-systems of ESMS, which consisted of six sub-systems, namely, traffic and weather monitor sub-system, road weather forecast and impact evaluation sub-system, advanced traffic management sub-system based multi-info resource, intelligent information dissemination sub-system, winter road maintenance decision-support sub-system, and emergency rescue sub-system.
