Abstract:Ningbo-Zhoushan Railway has been listed in the mid-term and long-term railway network planning. Its general trend is consistent with the double line of Ningbo-Zhoushan Expressway. By synthesizing the planning control, channel resources, engineering implementation period and other factors, the railway-highway co-construction can be considered. The necessity of railway-highway co-construction is studied from the perspective of traffic status, traffic demand, functional orientation, construction scheme and construction opportunity, which provides the reference for the study of similar channel construction schemes.
