对可靠性理论深入研究的基础上,对公交线网特性进行分析,筛选出公交线网可靠性的关键影响因素。从线网布局及拓扑结构入手,根据公交线网自身特性,借鉴路网可靠性指标分别定义了公交线网连通可靠性、出行时间可靠性、直达可靠性等,并建立数学模型,将量化的概率值引入公交线网可靠性研究之中。 Based on the in-depth study of reliability theory, this paper analyzes the characteristics of bus network and selects the key factors that influence the reliability of bus network. Starting from the layout and topology of the wire network, according to the characteristics of the bus network, the reliability of the bus network, the reliability of the travel time, the reliability of the travel time, and the reliability of the bus are defined respectively with reference to the reliability index of the road network. Mathematical models are established to quantify The probability value is introduced into the study of the reliability of bus network.
