【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。
[Abstract]:The expressway system that has been built in China is basically aimed at large cities and megacities with a population of 2 million or more, and few researches and practices have been done on cities with a population of about 1 million. The cities with a million people occupy a large proportion in the urban sequence of our country. It is the main carrier of urbanization population transfer. With the expansion of urban space, the travel radius obviously increases, especially in the mountainous cities or belt cities, the conventional trunk road system is difficult to meet the needs of fast travel. High-grade skeleton road system is urgently needed to support urban spatial expansion. This paper deeply analyzes the demand of transportation travel in the cities with millions of population, adopts the method of summing up the present situation and summarizing the cases of planning, and makes a systematic analysis of the expressway system of urban planning of millions of people. It is considered that the accurate definition of the urban expressway system for the vast majority of millions of people in China at present should be quasi-expressway system, and the preliminary definition, main technical indicators and recommended standards should be discussed. With a view to guiding the construction of urban skeleton network system on the scale of millions of people.
