【摘要】：公交优先是城市交通发展的趋势,是解决城市交通问题的优选措施。城市地面常规公交是城市公共交通系统的基础,具有投资节约、运行灵活、覆盖广泛、适用性强等特点。公交站作为公交运行的控制性节点,是最基本的交通瓶颈,是公交设施供给能力的决定性因素之一。利用智能交通技术合理设计公交站交通组织方案,并给出方案对应的公交站通行能力计算方法,对于改善公交站交通组织方式、合理设计公交站站台尺寸与线路容量等具有很强的指导意义。本文以多泊位公交站内车辆停靠过程分析为基础,重点解析了公交站通行能力主要影响因素的作用机理与效果,分析出车辆站内延误是影响公交站通行能力的直接因素；继而以改善公交站内交通组织秩序、减少车辆站内延误、提高公交站通行能力为目标,设计出以公交站台实时智能引导、公交车辆实时定点停靠与公交乘客实时定点排队为核心多泊位公交站实时排队诱导系统,并明确了系统内涵、系统目标、系统构成以及功能实现流程。通过分析实时定点停靠公交站内车辆停靠特征,定义了平均泊位延误,进而给出了系统下车队队长概率分布的模型以及不同队长对应的车队延误计算方法,最后提出实时排队诱导系统下多泊位公交站通行能力计算方法：车队通过数法。文章的最后利用成都常规公交站实测数据,标定了实时排队诱导系统下多泊位公交站通行能力计算模型中的参数,分析了实时排队诱导系统在提升多泊位公交站通行能力上的效果。
[Abstract]:Bus priority is the trend of urban traffic development and the best choice to solve urban traffic problems. Urban ground routine public transport system is the basis of urban public transport system, with investment savings, flexible operation, extensive coverage. As a controlling node of bus operation, bus station is the most basic traffic bottleneck. It is one of the decisive factors in the supply capacity of public transport facilities. The traffic organization scheme of bus station is designed rationally by using intelligent transportation technology, and the corresponding calculation method of traffic capacity of bus station is given. It is of great guiding significance to improve the traffic organization of public transport stations and to design the size and line capacity of bus stations reasonably. Based on the analysis of the parking process in the multi-berth bus station, this paper focuses on the mechanism and effect of the main influencing factors of the traffic capacity of the bus station. It is analyzed that the delay in the vehicle station is the direct factor that affects the traffic capacity of the bus station. In order to improve the traffic organization order, reduce the delay in the bus station, improve the traffic capacity of the bus station, the real-time intelligent guidance of the bus station is designed. Real-time fixed-point parking of public transport vehicles and real-time fixed-point queuing of public transport passengers are the core of real-time queue guidance system for multi-berth bus stations, and the system connotation, system objectives, system composition and function realization flow are defined. By analyzing the parking characteristics of the vehicles in the real-time fixed-point bus station, the average berth delay is defined, and the model of the probability distribution of the team captain under the system and the calculation method of the vehicle delay corresponding to the different captains are given. Finally, a method for calculating the capacity of multi-berth bus stations under real-time queue guidance system is proposed: the method of passing number of motorcade. At the end of the paper, the parameters of the capacity calculation model of multi-berth bus station under real-time queue guidance system are calibrated by using the measured data of Chengdu bus station. The effect of real-time queue guidance system on improving the capacity of multi-berth bus station is analyzed.
