【摘要】：我国解决城市交通问题的主要措施是发展公共交通系统。公交停靠站是城市交通系统及公共交通的重要节点,广泛分散于城市交通网络中。随着常规公交建设网络的不断完善,公交停靠站和公交线路数量不断增加,公交停靠站建设缺乏合理规划,使得公交车辆在停靠站处排队时间增加、车辆运营组织混乱等问题日益凸显,严重干扰了道路上其它社会车辆的正常运行,降低了道路通行效率。基于以上背景,论文在国内外研究现状和公交停靠站设置影响因素分析的基础上,重点研究了考虑道路通行能力影响的公交停靠站设置形式。首先归纳分析了我国公交停靠站的主要类型,总结直线式和港湾式停靠站的交通特性,从道路车道数、路段交通量、建设成本等角度出发分析了公交停靠站设置的影响因素。在分析道路通行能力影响因素的基础上,结合传统道路通行能力计算,提出公交停靠站设置形式选择必须考虑公交停靠站对道路通行能力的折减影响阈值。然后从进站、停靠和离站三个阶段分析了两种类型停靠站附近公交车辆的运行特征,考虑直线式停靠站车道到达服从泊松分布特征和港湾式停靠站公交车辆排队溢出概率,建立两种停靠站的延误影响时间模型。结合概率论、排队论和间隙理论,构建了两种类型公交停靠站对道路通行能力折减模型。最后通过对长春市六个公交停靠站的实际调研和数据分析,标定了模型中公交停靠时间、加减速时间、溢出概率等参数,并利用VISSIM软件检验了模型精度和有效性。同时利用折减模型及停靠站设置选择方法研究了两种类型停靠站的设置形式,以期为城市道路规划和公交站点形式设置提供参考。
[Abstract]:The main measure to solve the urban traffic problem in China is to develop the public transport system. Bus stop is an important node of the urban transportation system and public transportation, which is widely dispersed in the urban transportation network. The increasing number of bus stops and bus lines, the lack of reasonable planning for the construction of bus stops, the increase in the queue time of public transport vehicles at the stop, the confusion of vehicle operation and other problems have become increasingly prominent. It seriously interferes with the normal operation of other social vehicles on the road and reduces the road traffic efficiency. Based on the above background, this paper analyzes the current research situation at home and abroad and the influencing factors of bus stop setting. Firstly, the main types of bus stops in China are summarized and analyzed, and the traffic characteristics of straight-line and harbor stations are summarized, including the number of road lanes and the traffic volume of road sections. Based on the analysis of the influence factors of the road capacity and the traditional road capacity calculation, the paper analyzes the influence factors of the bus stop setting from the point of view of construction cost. It is proposed that the threshold value of the reduction effect of bus stops on road capacity must be taken into account in the selection of bus stops, and then the operation characteristics of two types of public transport vehicles near the stations are analyzed from three stages: inbound, docking and disembarking. Considering the distribution characteristics of lane arrival service from Poisson and the queue overflow probability of bus at the port station, this paper establishes the delay influence time model of two kinds of stop, and combines probability theory, queuing theory and gap theory, establishes the model of delay influence time of two kinds of stops, and combines probability theory, queuing theory and gap theory. Finally, through the actual investigation and data analysis of six bus stops in Changchun, the parameters such as bus stop time, acceleration and deceleration time, overflow probability and so on are calibrated. The accuracy and validity of the model are tested by using VISSIM software, and the two types of parking stations are studied by using the reduction model and the method of station selection, in order to provide a reference for urban road planning and bus station layout.
