Research on Huixian South Interchange of Anyang to Xinxiang Expressway
In the paper,the Huixian South Interchange at the ending point of the Hebi to Xinxiang Section of Anyang to Xinxiang Expressway(An-Xin Expressway)is taken as the study object.From the perspective of mutual communication to meet the traffic function,combined with the surrounding status of expressways,villages,high-voltage lines and other control factors,three schemes are proposed.Comparisons are carried out respectively from the land occupation area,project cost,construction difficulty,and finally Scheme 1 is selected as the recommended scheme.Scheme 1 combines the existing Huixian South Interchange into a composite interchange,which can not only solve the functions of traffic conversion between An-Xin Expressway and other expressways but also realize the functions of serving the surrounding towns.Scheme 1 can also avoid the formation of a five way hub interchange between An-Xin Expressway,Heze-Baoji Expressway and Zhengzhou-Huixian Expressway to increase project cost and land occupation.The paper solves the traffic conversion problem among multiple expressways from another perspective,which can provide reference for other similar projects.
