Abstract:Regional overall development is a new model of urban construction and urban renewal. Road traffic, as an important regional infrastructure support, should not only meet the basic functional needs of vehicles, but also combine the functional positioning of urban areas to establish a high-quality public activity space for people, vehicles and the environment to adapt and integrate. Taking the scheme design of Sanlinwan Town Road Traffic Project in Sanlin Riverside South Area as an example, starting from the function orientation, a peaceful and pleasant calming traffic travel environment is built, and the traffic goal of slow traffic first, quiet and comfortable environment, and fast and slow traffic separation is realized. According to the design concept, the different functional road systems are compared and selected. The contents can be used as a reference for the overall development of infrastructure construction projects in high quality urban areas.
