公交优先规则下的路阻函数研究
发布时间：2019-02-12 10:15
【摘要】：随着城市交通拥堵的加剧,“公交优先”已成为多数城市解决交通问题的首要选择。从“公交优先”的内涵来看,“路权优先”则是“公交优先”政策实施的具体表现,而公交车在不同路权下的行驶特点也不尽相同,已不再适用传统的路阻函数来表示公交车的行驶特点。同时,“公交优先”的理念,也需要针对公交车的运行特点,分析公交车在路段上行驶的运行规律,构建出适合公交车的路阻函数。而传统路阻函数忽略了公交车与其他车辆运行特征的不同,不能反映出车辆之间因差异存在而产生的干扰现象,已不再适用。因此,需要对公交优先规则下公交车和其他车辆的路阻函数进行新的研究。本文从公交车辆的运行特征着手,从公交线路条数、站点停靠过程、客流量等方面对公交车辆之间的相互影响过程进行了分析;从公交站点类型、公交专用道设置等方面分析了公交车对其他车辆的影响。针对封闭式独立路权下的公交车辆,从公交线路的运行规律入手,认为封闭式独立路权下公交车的延误分为站点停靠延误、出站汇入车流延误和交叉口信号控制延误等三个方面;分别利用排队论、间隙理论、信号控制理论等理论为基础,建立了三方面的延误模型,并最终得到了公交车的路阻函数模型;最后通过具体算例对公交车路阻函数进行了计算,并通过与BPR函数计算结果进行比较,证明了文章提出的公交车路阻函数的合理性。针对非封闭式独立路权下的车辆,公交车辆与其他车辆处于混行状态,分析了混行状态下公交车在运行过程中在基本路段和公交站点处对其他车辆产生的影响;此时的公交车可认为是路段上行驶的“移动瓶颈”,根据移动瓶颈的相关理论,建立了其他车辆受公交车干扰的延误模型,并得到了其他车辆的路阻函数模型;最后,通过具体实例对文章提出的其他车辆的路阻函数进行了计算,并通过与BPR函数计算结果的比较,证明了文章提出的模型更能反映实际,更科学合理。
[Abstract]:With the aggravation of urban traffic congestion, bus priority has become the first choice to solve traffic problems in most cities. From the connotation of "bus priority", "right of way priority" is the concrete manifestation of the implementation of "bus priority" policy, and the driving characteristics of buses under different road rights are also different. It is no longer suitable for the traditional road resistance function to represent the driving characteristics of the bus. At the same time, the concept of "bus priority" also needs to analyze the running rules of the bus on the road, and to construct the road resistance function suitable for the bus according to the operation characteristics of the bus. But the traditional road resistance function neglects the difference between the bus and other vehicles, and can not reflect the interference between the vehicles because of the difference, so it is no longer applicable. Therefore, it is necessary to study the road resistance function of buses and other vehicles under bus priority rules. In this paper, the operation characteristics of public transport vehicles, from the bus line number, stop process, passenger flow and other aspects of the public transport vehicle interaction process is analyzed. The influence of bus on other vehicles is analyzed from the aspects of bus station type, bus lane setting and so on. In view of the public transport vehicle under the closed independent road right, starting with the running rule of the public transport line, it is considered that the delay of the bus under the closed independent road right can be divided into stop delay and stop delay. There are three aspects: the traffic flow delay and the signal control delay at the intersection. On the basis of queuing theory, gap theory and signal control theory, three delay models are established, and finally the road resistance function model of bus is obtained. Finally, the bus road resistance function is calculated by a concrete example, and compared with the result of BPR function, which proves the rationality of the bus road resistance function proposed in this paper. In view of the vehicle under the non-closed independent road right, the public transport vehicle is in the mixed state with other vehicles, and the influence of the bus in the basic section and the bus station on other vehicles in the mixed state is analyzed. At this time, the bus can be considered as the "moving bottleneck" on the road. According to the theory of the moving bottleneck, the delay model of other vehicles is established, and the road resistance function model of other vehicles is obtained. Finally, the road resistance function of other vehicles proposed in this paper is calculated by concrete examples, and compared with the result of BPR function, it is proved that the model presented in this paper can reflect the reality more scientifically and reasonably.
