摘　　要：环行交叉口流向流量和交织段运行特性复杂,直接观测存在困难。在分析环行交通流运行特性基础上,提出了指导观测断面优化布设的原则和方法,用实例对各进口流向流量和交织段的观测和推算进行了应用说明。It is difficult for people to survey the traffic flow directions and traffic volumes at roundabouts directly because of the complicated traffic flow directions and traffic volumes at the roundabouts and the complicated operation characteristics at the weaving sections of roads. Based on analysis of operation characteristics of rotary traffic flow, the principles and methods of the optimum arrangement of survey sections are presented in this paper. An example is given to explain the survey and calculation of the traffic flow directions and traffic volumes at the entrances of the roundabouts and at the weaving sections of roads.
