摘要
自古以来城市多临江河建立,江河水域对于城市的交通有着显著影响。文章选取武汉、上海、广州、重庆、杭州、长沙、宁波等7个典型临江城市,创新性提出“绕行指数”的概念并建立相应数学模型分析这7个城市的临江交通绕行特征以及影响其绕行的因素。研究包括机动绕行、非机动绕行以及城市公共交通绕行等3个方面,发现江河水面宽度、江河水域密度、跨江河桥梁通航净高以及江河两岸地形地势均对城市的临江交通绕行有着不同程度的影响。对此文章提出部分位于城市地理中心的临江地段可能不仅难以具有与其区位优势相匹配的交通便利性,甚至可能成为城市中某种意义上的“交通终端”,进而认为在城市的区域规划中应当对这一问题进行充分考虑并据此优化城市的产业布局。
Since ancient times,cities have often been built along rivers,and rivers have had a significant impact on urban traffic.This article selects 7 typical riverside cities in China,including Wuhan,Shanghai,Guangzhou,Chongqing,Hangzhou,Changsha,and Ningbo,and innovatively proposed the concept of"detour index"and established corresponding mathematical models to analyze the detour characteristics of riverside traffic in these 7 cities and the factors that affect their detours.The study includes three aspects:motorized detours,non-motorized detours,and urban public transportation detours.It is found that the width of the river,the density of the river,the clear navigable height of the bridges across the river,and the topography of both sides of the river have different degrees of impact on the city’s riverside traffic detour.In this regard,this article proposes that some riverside areas located in the geographic center of the city may not only have difficulty in having transportation convenience that matches their location advantages,but may even become a certain"terminal of transportation"in the city.This issue shall be fully considered and the industrial layout of the city shall be optimized accordingly.
