摘　　要：国内已建成的快速路系统,基本上均针对200万人口及以上的大城市及特大城市,对于100万人口左右的城市鲜有研究与实践,而百万人口城市在我国城市序列中占有较大的比例,是承载城镇化人口转移的主要载体。随着城市空间的拓展,出行半径明显增加,尤其是组团型山地城市或带形城市,常规的主干路系统难以适应快捷出行需求,急需技术等级较高的骨架道路系统支撑城市空间拓展。深入分析百万人口城市的交通出行诉求,采用现状总结与规划案例归纳的方法,对百万人口城市规划"快速路系统"进行系统分析,认为现阶段我国绝大多数百万人口城市快速路系统准确定义应为准快速路系统,并探讨其初步定义、主要技术指标、推荐标准等,以期指导百万人口规模城市骨架路网系统建设。China has built a fast road system, basically for 2 millions people and above large cities and mega-eities, however, for the city of about 1 million people, there is rarely research and practice. The proportion of urban population is carrying the main carrier of the transfer. With the expansion of urban space, the radius of travel increased significantly. It is difficult to adapt to the thst travel demand, and there is the need for higher technical level skeleton road system to support urban space expansion. With the depth analysis of the population of the city＇s traffic demand, the paper studied the use of the status quo summary and planning case induction method, implemented the one million population urban planning ＂expressway system＂ system analysis. It is found that the system should be precisely defined as the quasi-expressway system. Its initial definition, the main technical indicators, and recommended standards should be further discussed.
