信号交叉口服务水平是衡量交叉口运行状况以及使用者对其运行质量的感受的重要的定性指标,它既是交叉口设计和交通管理控制措施确定的依据,也是交通设施运行状态评价的基础。本文综述混合交通条件下信号交叉口机动车、行人、自行车服务水平的确定方法、技术和主要成果。在此基础上,展望该研究在我国的发展动向。 The service level of the signalized intersection is an important qualitative indicator to measure the operation status of the intersection and the user’s perception of its operation quality. It is not only the basis for determining the design of the intersection and the traffic control measures, but also the basis for evaluating the operation status of the traffic facilities. This article summarizes the methods, techniques and main achievements of the service level of motor vehicles, pedestrians and bicycles at signalized intersections under mixed traffic conditions. On this basis, we will look forward to the development of this research in our country.
