Study on Reconstruction Scheme of Shierying Hub Interchange in Anpan Expressway
In order to propose an optimal reconstruction scheme for the Shierying Hub Interchange in Anshun-Panzhou Expressway,the optimization suggestions are proposed for the previous phase of the scheme by analyzing the construction conditions,road network structure and previous-phase scheme,and predicting the road network traffic volume and interchange turning traffic volume.Tow interchange schemes are proposed again.At the same time,through the comparison of route indicators,driving safety,service level,highway land use,interference to existing buildings and structures in the surrounding area,engineering quantities and costs,the two interchange schemes are compared.Finally,Scheme 1 is recommended as the interchange reconstruction scheme.The cost is greatly saved and also the traffic functions are met.The design experience of this interchange reconstruction is summarized in order to provide the reference for the reconstruction of similar interchanges.
