沪嘉城际对嘉兴市域线的影响

Impact of Shanghai-Jiaxing Railway on Urban Lines in Jiaxing

市域线主要实现中心城区、市域组团、周边新城的连接,现处于快速发展阶段,而随着城市不断地向外围拓展,已涌现出大量的城市群,各相邻城市之间的交通联系日益密切,尤其在经济发达的长三角、珠三角等地区规划较多的城际线,以便实现相邻城市间的公交化出行,而市域线与城际线的功能定位有较大差别,城际线在一定程度上会影响市域线的规划布局。在研究沪嘉城际线与嘉兴市域线各自特点的基础上,通过梳理二者之间的差异性,并考虑到嘉兴市域各副中心与市区之间的联系,对比分析沪嘉城际、嘉兴市域线二者的功能定位,并结合临沪组团和非临沪组团与市区的交通量需求,得出较为合理的方案,可为类似城市的市域线规划提供参考。

The urban area line mainly realizes the connection of the central urban area,the urban area groups,and the surrounding new cities,which have already entered a rapid development stage.As the city continues to expand outward,many urban agglomerations have sprung up,and the traffic links between adjacent cities are getting closer day by day,especially in the economically developed Yangtze River Delta,Pearl River Delta,and other regions.More intercity lines were planned in such a way as to realize bus transportation between adjacent cities.The functional orientations of urban area lines and intercity lines differ greatly.The intercity line influences the layout of the city line to some extent.In this study,based on the characteristics of the Shanghai-Jiaxing Railway and the urban line in Jiaxing,the differences between the two were combined,and the relationship between the subcenters and the city was considered.A comparative functional analysis between the Shanghai-Jiaxing Railway and urban lines in Jiaxing,which also combines the traffic demand of the groups near Shanghai and of those not near Shanghai with the urban area,was performed,and a rational approach was selected.This study provides a reference for similar domestic cities.
