Analysis on Factors of Adding Service Interchange in Existing Expressway for S32
Under the background of rapid urban development,the built expressway network structure system has gradually been in the urban area.There is an increasing contradiction between the large distance between the entrance and exit of the existing expressway interchange and the urgent need for quick access to the expressway network.Taking Kunyang Road Interchange Project in S32 Shanghai-Jiaxing-Huzhou Expressway as an example,the technical characteristics of the overall scheme design for adding the service interchange toll ramp of the existing urban expressway are summarized from the addition of expressway service interchange project location and interchange selection analysis,traffic impact characteristics analysis,reasonable application of new materials and other related factors.The design idea of using new materials reasonably to solve the electromagnetic interference of toll collection system and pavement structure layer is put forward in order to provide the technical reference and guidance for the subsequent addition of service interchange entrances and exits on urban expressways.
