"Small Incision"Reconstruction Design Scheme of Ring Road Ⅱ in Xi'an City
Ring Road Ⅱ in Xi'an City is the basic contact circle of the radial line group of the built expressway in the main city of Xi'an City.With the number of vehicles in Xi'an City approaching five million,at the beginning of the construction of the expressway,various traffic defects that were not obvious become increasingly prominent.The traffic delay caused by"point-to-surface"has become normal and cannot meet the traffic demand in the new era.However,the overall upgrading and recon-struction of Ring Road Ⅱ at this stage has not only a large investment and a long construction period,but also a great impact on the urban traffic of Xi'an City.Therefore,based on the traffic function positioning of Ring Road Ⅱ,at this stage,the"small incision"reconstruction is carried out on the partial congestion points of Ring Road Ⅱ,which improves the overall traffic capacity and alleviate the congestion.The overall reconstruction scheme has the reconstruction classification on 11 traffic congestion points.Taking the congestion points as the example,the present problems are separately analyzed,and the"small incision"reconstruction scheme is introduced in detail.After the implementation of the project,the overall traffic capacity of Ring Road Ⅱ is improved by 4％～6％,which can be referred for the reconstruction by stages of the early built expressways severely restricted by the condition leading to the difficulty of thorough reconstruction.
