摘 要： 探讨公路交通指南标记对信号交叉口饱和流速的影响。研究人员采用了调整因子模型，通过对多个交叉口的实际交通流数据进行观测和分析，对不同类型指南标记，在交叉口流速中的差异进行研究，并考虑不同转向角情境下的影响。通过对交叉口饱和流速的模拟和对比分析，研究人员得出结论：某些特定类型的指南标记对流速产生显著影响，可能导致饱和流率的提高或降低。同时，转向角度对指南标记的影响存在一定的规律，研究发现在某些角度下，指南标记对流速的调节效果更为显著。对优化信号交叉口设计、提高交叉口通行效率具有重要意义，为交通规划者提供了实用的指导，有助于合理设置公路交通指南标记，以最大程度地提升交叉口的运行效率。

Abstract： This study aims to explore the impact of road traffic guide marks on the saturated flow rate at signalized intersections. Researchers employ an adjustment factor model to observe and analyze actual traffic flow data at multiple intersections， and study the differences of various types of guide marks in the flow rate at intersections， taking into account the influence of different steering angle scenarios. Through the simulation and comparative analysis of the saturated flow rate at intersections， researchers conclude that some specific types of guide marks have a significant impact on the flow rate， potentially leading to an increase or decrease of the saturated flow rate， there is a certain law in the influence of steering angles on guide marks， and that guide marks have more significant effects in regulating the flow rate at some angles， which is of great significance for optimizing the design of signalized intersections and improving the traffic efficiency of intersections， and provides practical guidance for traffic planners， so as to help the rational setting of road traffic guide marks to maximize the operational efficiency of intersections.
