首先对交叉口可靠性的概念和影响因素进行了系统分析,并且在可靠性理论的基础上,引入基于车道路网模型,建立了以饱和度为指标的交叉口可靠性计算模型,并应用实例进行求解论证,表明此方法可行。这种计算模型可以找出交叉口中每个转向或进口道的薄弱点,进而为交通管理措施的实施提供一个有力的工具。 Firstly, the concept and influencing factors of intersection reliability are systematically analyzed. Based on reliability theory, the road network model based on road network is introduced to establish the intersection reliability model with saturation as an indicator, and the application example Solve the argument, indicating that this method is feasible. This computational model can identify the weak points of each steering or crossing at an intersection, thus providing a powerful tool for implementing traffic management measures.
