【摘要】：公交停靠站作为公共交通系统中的重要节点，公交停靠站设计的合理性不仅对公共交通的运营效率和服务水平有重要的影响，而且对于城市道路交通的通行能力和服务水平同样具有重要的影响。公交停靠站区域是反映对停靠站研究范围的界定。设计公交站停靠站的一个重要参数是停靠站的区域长度，不合理的停靠站区域长度设计会导致停靠站通行能力的下降，增加停靠站的延误。 本文在分析公交停靠站区域长度的计算方法，对比不同方法的适用范围、特点及局限性基础上，分别研究了单泊位和多泊位条件下，，公交停靠站区域长度与泊位数、最大通行能力之间的关系。基于马尔可夫链，建立了公交停靠站平均排队长度模型。在高峰时段，车辆到达满足泊松分布，基于马尔可夫的停靠站区域长度模型，确定停靠站的区域长度。 运用VISSIM仿真软件，对典型的公交停靠站进行仿真，验证马尔可夫模型在确定停靠站区域长度的可行性及合理性。然后，对典型的公交停靠站进行改造方案的研究，通过平均排队长度、最大排队长度以及公交车辆的延误等统计结果，最优方案为区域长度43.62m的港湾式停靠站，优化现有的停靠站区域长度。
[Abstract]:As an important node in the public transport system, the rationality of bus stop design not only has an important impact on the operation efficiency and service level of public transport. Moreover, it also has an important influence on the capacity and service level of urban road traffic. The area of bus stop reflects the definition of the research scope of bus stop. An important parameter in the design of bus stop is the area length of the stop. Unreasonable design of the regional length of the stop will lead to the decline of the capacity of the stop and increase the delay of the stop. On the basis of analyzing the calculation method of the length of the bus stop area, comparing the applicable range, characteristics and limitation of different methods, the paper studies the length and number of the bus stop area under the condition of single berth and multi-berth, respectively. The relationship between maximum capacity. Based on Markov chain, the average queue length model of bus stop is established. During the rush hour, the arrival of the vehicle meets the Poisson distribution, and the regional length of the stop is determined based on the Markov model of the regional length of the stop. The VISSIM simulation software is used to simulate the typical bus stop to verify the feasibility and rationality of Markov model in determining the length of the stop area. Then, through the statistical results of the average queue length, the maximum queue length and the delay of the public transport vehicle, the optimal scheme is 43.62m port station with the area length of 43.62m. Optimize the existing docking area length.
