超大城市“半入城”高速公路适应性研究——以广州为例

Adaptability of the"Entering City"Expressway in Super Cities:A Case Study of Guangzhou

如何解决区域存量高速公路功能城市化、混杂的问题是城市发展不可回避的。以广州为例,回顾广州城市发展,通过中心城区与外围城区骨架道路交通特征的分析,剖析“入城”高速公路交通特征及面临的交通困境,结合未来城市发展趋势,提出不同区域发展定位下的3种高速公路功能优化模式,并以广州多种典型高速公路作为案例,充分阐述其优化思路及方案,为超大城市高速公路功能优化“再突围”提供可借鉴经验参考。

How to solve the problems of urbanization and mixed function of regional existing expressways is an unavoidable problem in urban development.Taking Guangzhou as an example,this paper reviews the urban development of Guangzhou,analyzes the traffic characteristics of the"inbound"expressway and the traffic difficulties it faces through the analysis of the skeletal road traffic characteristics of the central and peripheral urban areas,and combines the future urban development trend to propose three functional optimization modes of expressway under different regional development positioning,and takes various typical expressways in Guangzhou as cases.Its optimization ideas and schemes are fully expounded.It provides a reference for the function optimization of super city expressway"re-breaking".
