As the main link connecting the city, suburbs and industrial parks, the expressway must meet the needs of inter-city expressway transportation on the one hand, and play a role in supporting the normal operation of the city on the other hand. This paper firstly analyzes the main characteristics of China's urban expressways according to the current research situation, and proposes three key points for the design of China's urban expressway traffic system. The two methods are compared and selected, which proves the rationality of the design focus of China's urban expressway traffic system. The thesis proposes that in the overall design process, various factors such as the characteristics and scale of urban highways, urban geographical environment and social and economic development trends should be taken into account to ensure that the overall planning and design of highways meet the actual requirements of the city, and provide the basis for future highway construction projects. It provides a solid foundation for the smooth development.
