Abstract: 路网密度、路网等级结构、道路面积率是城市路网规划的关键指标国内外24个CBD案例的路网和轨道交通设施配置与用地开发强度(容积率)的相关性和因子回归分析表明:①干路、长支路的路网密度,及其在总路网密度中所占比例,与CBD容积率正相关;②长支路的路网密度与容积率、建筑密度、道路放射密度、轨道放射密度、折合轨道站点密度正相关,具有交通结构优化作用;③CBD的道路放射密度、轨道放射密度、建筑密度是影响CBD容积率的重要因素;④道路面积率与CBD容积率微弱负相关.在路网规划关键指标对CBD容积率影响机理解析和国内外CBD交通设施配置指标比较的基础上,对CBD和非CBD的路网规划提出相关建议.
