现代化都市圈轨道交通规划思考与广州探索

建设现代化都市圈是实现城市群高质量发展、实践新型城镇化的重要途径。都市圈轨道交通已成为实现都市圈时空高效组织和交通一体化的必要条件。目前，中国以超大城市为中心、1 h通勤圈为基本范围的都市圈已初具雏形，尤其以广州为中心的都市圈已发展相对成熟。基于都市圈内涵辨析，总结国外都市圈及轨道交通发展的相关经验，分析目前国内都市圈跨城通勤出行及轨道交通特征，回顾广州在都市圈轨道交通规划方面3个阶段的探索历程，总结经验并重点提出需要注意的4个方面，为建设现代化都市圈和有条件地区编制都市圈轨道交通规划提供经验参考。

Rail Transit Planning in Modern Metropolitan Areas and Exploration in Guangzhou

Building a modern metropolitan area is an important way to achieve high-quality development of urban agglomerations and new urbanization. Rail transit has become a necessary foundation to realize the development of spatio- temporal efficiency and transportation integration in metropolitan areas. At present, metropolitan areas with a megacity as the center and the one-hour commuting circle as the basic boundary have begun to take shape. Particularly, the metropolitan area centered on Guangzhou has developed. First, by discussing the connotation of the metropolitan areas, we summarize the relevant experience of international metropolitan areas and rail transit development. Second, we analyze intercity commuting and rail transit characteristics of the current urban circle. Finally, we discuss the practice of urban rail transit planning in Guangzhou and provide empirical references for the construction of modern metropolitan areas and conditional areas for the preparation of metropolitan rail transit planning.
