摘　　要：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;(3)CBD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。Road network density, road network grade structure, road area ratio are key indicators of road network planning. Based on data about road network, rail transit facilities and development Intensity （FAR, floor area ratio） of 24 CBDs worldwide, the paper applies correlation and factor analysis and draws the follow- ing conclusions： 1） the length and density of arterial roads and long access road- shave positive correlation with CBD FAR; 2） density of the long access road net- work is positively related to CBD FAR, and building density, road radiation densi- ty, rail transit radiation density and related rail transit station density have optimi- zation effects on traffic; 3） CBD road radiation density, rail transit radiation densi- ty and building density are important factors to support CBD FAR as well; 4） Road area ratio shows weak negative correlation with CBD FAR. The paper dis- cusses the impact of key indicators on road network planning, compares traffic facility allocation indices of CBD between China and abroad, and provides sugges- tions on road network planning.
