摘　　要：为明确交通瓶颈对快速公交运行效率的影响并制定改善措施,以大连市快速公交1号线上的交通瓶颈为研究对象,分析各瓶颈处交通流量、通行速度和服务水平,以及各瓶颈对快速公交线路的影响.从设施建设和交通组织两方面制定改善措施,原则是尽可能利用交通管理方法在提高快速公交效率的同时,保持其他车辆服务的水平.交通流仿真表明,采取的措施可使快速公交运行速度达到25 km/h,其他车辆的运行速度达到40 km/h.A planned Dalian BRT （bus rapid transit） No. 1 line was studied to know the impacts of bottleneck on the efficiency of BRT operation and make improving methods. A traffic survey method was developed and traffic volume, vehicle speed and traffic service level as well as effects of the bottlenecks were analyzed. Improvement schemes were set up for the most serious bottleneck in aspects of infrastructure construction and traffic management, while the traffic management was more preferred. The traffic flow simulation results show that the methods suggested here can enhance the BRT efficiency, while keeping the other vehicles service level, and speed of BRT and other vehicles reaches 25 km/h and 40 km/h respectively.
