摘要：公共交通是解决CBD交通问题最为有效的途径，也是CBD规划中最为核心的问题之一。结合武汉王家墩CBD公共交通规划，着重对国际成功CBD的公共交通分担率和公交发展模式进行了研究，提出了CBD就业密度与公共交通分担率之间存在正相关性，总结出CBD公共交通系统可抽象化为三级模式，并依据客流预测分布，构建了以骨架线为主体、公交干线为基础、公交支线为补充的公共交通服务体系，形成了多层次、网络化、一体化的公共交通系统。

Abstract: Public transportation is one of the most effective and important means to get people in and out of a CBD area. Based on overseas successful cases in CBD public transportation planning, this paper provides a positive correlation between CBD employment density and public transportation mode share, and presents a three-hierarchy public transportation modal based on transit ride-ship forecasts, which can be used to develop a hierarchical, networking, and integrated public transportation system within a CBD area that uses the backbone-lines as the primary network, arterials as its basic components, and the branch lines as the supplementary routes.
