摘　　要：在对我国各特大城市CBD交通情况进行调研的基础上,从通行能力、路网密度、道路比重、单位道路荷载等方面进行量化研究,探讨我国CBD路网模式的自身规律,并对我国CBD两种典型路网模式进行分析,结果表明,高密度均质路网模式不仅在路网顺畅度、单位道路荷载方面占有明显优势,而且在生活多样性方面也优于低密度等级路网模式。The CBD transportation networks in several major Chinese cities were surveyed to assess passing ability, road network density, road area ratio, per capita transportation capacity, etc. Typical CBD road network characteristics were assessed and the two common network models are analyzed. The high density evenly distributed road model provides advantages in transportation flow and capacity and also creates more diversity than a low density road network.
