城市越江交通规划建设关键问题研究

越江交通是支撑城市跨江发展的主要因素，合理的越江通道布局和建设模式成为城市越江交通的关键。结合上海越江交通发展现状，从越江交通布局和通道建设两个层面入手，阐述了越江交通规划和建设的关键问题。通过相关案例分析和网络建模分析，越江通道规模除了与城市规模相关以外，与河流宽度具有较强的相关性。在建设层面，多通道分散越江模式、多接线模式具有明显的优势。

Research on Key Issues in Planning and Construction of Urban River-crossing Traffic

River-crossing transportation is the main factor supporting the river-crossing development of city. The reasonable layout and the construction mode of river-crossing channel have become the key of urban river-crossing transportation. Combined with the current development situation of river-crossing transportation in Shanghai, the key issues in the planning and construction of river-crossing transportation are expounded from two aspects of river-crossing transportation layout and the channel construction. Through the related case analysis and network modeling analysis, the river-crossing channel scale has the stronger correlation with the river width in addition to city scale. In the construction aspect, the multi-channel dispersed river-crossing mode and the multi-connection mode have the obvious superiority, which hopes to provide experience, reference and reflection for planning and construction of urban river-crossing transportation.
