城市轨道交通半径线研究

通过分析半径线概念的起源、特征以及当前我国轨道交通规划中存在的半径线问题,明确半径线研究的目的。通过对世界范围内随机选取的39个城市轨道交通线网进行分析,发现半径线在世界上具有较广泛的应用,且本身具有独特的适用性。进一步分析26个含有半径线的线网样本,发现半径线的成因包括城市地理特征、规划及实施因素。针对我国"半径线"问题的成因及特点提出了优化建议,从适用性、规划策略、实施方案及运营组织等方面给出了解决措施。

Research on Radius Line of Urban Rail Trasit

By analyzing the origin, characteristics and planning issues that exist in the field of China''s rail transit planning about "Radius line", make a clear purpose on the research of it. Through analysis of 39 urban rail transit networks that were worldwide randomly selected, we found the radius line was widely used in the world and had its unique applicability. By further analysis about 26 network samples which contained radial line, we conclude the cause of radius line including urban geography, planning and implementation factors. Then according to the cause and characteristics of the "radius line" in China, we put forward optimization suggestions, from the aspects of applicability, planning strategy, implementation plan and operation organization and so on.
