In order to be environment-friendly, relieve traffic congestion, reduce pollution, and be green and sustainable, the optimization and development of public transportation, as the subject of people's long-term research, has always been shining. With the emergence of shared transportation, public transportation systems face more challenges. In order to better connect with bike-sharing, car-sharing, and other modes of transportation, public transportation will carry out important reforms, among which the optimization of line network is one of the most important tasks. The traditional bus route design is mainly based on the “four-stage” method model, which is mainly based on the investigation and analysis of the existing traffic system and land use. Through the work flow of “evaluation, calibration, and verification,” the network balance optimization model is used to get the bus travel allocation prediction model. In this paper, the optimization problem of public transit network is studied from the point of view of the reliability of public transit network. It is proposed that public transit network can be abstracted into series-parallel system and parallel-series system model from the three states of normal, short-circuit failure, and open-circuit failure and is analyzed and discussed through the hypothesis experiment. The research of this paper will provide a new perspective for the optimization of public transit network, complement the traditional methods, and support the optimization and reliability improvement of urban public transit network. More reliable bus networks and other modes of transportation, such as walking, bike-sharing, and rail, will become more suitable for people to get around.

考虑三态可靠性的公共交通网络设置优化探讨

为了环保、缓解交通拥堵、减少污染、绿色可持续,公共交通的优化与发展作为人们长期研究的课题,一直闪耀着光芒。随着共享交通的出现,公共交通系统面临更多挑战。为了更好地与共享单车、汽车共享等交通方式对接,公共交通将进行重大改革,其中线路网优化是最重要的工作之一。传统公交线路设计主要基于“四阶段”法模型,主要基于对现有交通系统和土地利用的调查分析。通过“评估、校准、验证”的工作流程,”利用网络平衡优化模型得到公交出行分配预测模型。本文从公交网络可靠性的角度研究公交网络优化问题。提出公共交通网络可以从正常、短路故障和开路故障三种状态抽象为串并联系统和并联串联系统模型,并通过假设实验进行分析和讨论。本文的研究将为公交网络优化提供新的视角,对传统方法进行补充,为城市公交网络的优化和可靠性提升提供支持。更可靠的公交网络和其他交通方式,如步行、共享单车和铁路,
