Abstract:In recent years, with the economic and social development of the central urban area of Yantai, the expansion of urban space, the growth of motor vehicle ownership, and the continuous increase of the traffic volume and travel distance, there is an urgent need for an efficient and convenient expressway system as support. In response to the existing problems in the current traffic operation and planned expressway network in the central urban area of Yantai, and on the basis of interpreting the higher-level planning, the development trend of the central urban area of Yantai is studied and judged, the future travel demand is reasonably analyzed, and the optimization scheme for the layout of the expressway network is established. Finally, the scheme of Shanhai Road Expressway is designed in detail, which ensures that the overall scheme is reasonable and feasible, and provides the reference for subsequent engineering design.
