智慧公路发展与研究大综述 (2025): 交通安全理论方法及技术应用

Smart highways refer to the comprehensive perception and autonomous decision-making intelligent highway system constructed through the integration of new generation information technologies, e. g., big data, cloud computing, Internet of Things, and artificial intelligence. China’ s highway mileage ranks the first in the world, but the traffic safety situation is still severe. The smart highway construction has become an inevitable choice to improve traffic safety, efficiency, and management capabilities. This study systematically reviews the research progress of theoretical methods and technological applications in the field of smart highway and traffic safety from multiple dimensions, e. g., human, vehicle, road, environment, and digital intelligence management. The focus is on exploring the research themes, i. e., road infrastructure and traffic safety, vehicle-infrastructure coordination and traffic safety, and digital intelligence management and traffic safety. The domestic and overseas comprehensive research and application practices indicate that smart highways can effectively reduce accident risks; however, there is an urgent need to break through issues, e. g., human-machine interaction complexity, data security, and technical standardization. By systematically summarizing the existing theoretical methods and technological application bottlenecks, it is proposed to deepen the research on mixed traffic flow theory, digital twin safety management system, and autonomous prevention and control technology in the future. It will provide the theoretical support and practical reference for the sustainable development of smart highway traffic safety.
