【摘要】：本研究以有轨电车半独立路权下交叉口运行效率作为研究对象,研究不同条件下有轨电车半独立路权交叉口运行中有轨电车与道路交通之间的协调性和冲突安全性。首先,介绍了半独立路权下有轨电车信号优先设置的三种方式；其次,通过交通仿真分析方法,进行初步探讨,得出了关于半独立路权下各种信号优先方式适用性的初步规律；第三,在交叉口初步模拟分析和现状层次分析与数据包络方法回顾的基础上,提出了融合层次分析与数据包络的多指标评价方法;最后,论文设计了由多因素的不同取值组合而成的多个场景,并运用融合层次分析与数据包络的多指标评价方法对仿真结果进行了评价分析,得到了各影响因素对于有轨电车半独立路权下交叉口运行的单一影响和综合影响。具体来说,主要研究内容和结论如下： 1)阐述了交叉口有轨电车信号优先的三种基本方式及其具体实现方法,定性分析了被动优先、主动优先和实时优先三种信号优先方案的适用性。同时,分析了在有轨电车不同信号优先方式条件下,有轨电车进站上游停车和下游停车两种方案之间的差异。 2)针对信号优先方式适用性评价问题,提出了一种融合层次分析与数据包络的多指标评价方法。该方法不仅可以克服层次分析法中因主观判断所造成的判断结果不确定性问题,同时可以充分发挥层次分析方法在建立评价层次体系,推进多指标融合方面的优势；该方法比较适用于半独立路权下有轨电车交叉口运行效率的评价。 3)指出影响交叉口运行效果的五个主要因素为：有轨电车信号优先方式、有轨电车交叉口停站方式、相交道路与有轨电车沿线道路平均车道流量比(简称相交道路流量比)、有轨电车运行速度与道路交通运行速度；设计了288个不同的组合仿真情景,并通过融合层次分析与数据包络的多指标评价方法分析了仿真结果,根据冲突安全性和服务水平评价了每个方案的运行效益值。论文据此分析了所有影响因素对半独立路权下交叉口运行的单独影响及综合影响。
[Abstract]:This study takes the operation efficiency of tram semi-independent right intersection as the research object, and studies the coordination and conflict safety between tram and road traffic in the operation of tram semi-independent right intersection under different conditions. First of all, the paper introduces three ways of setting up the signal priority of tram under semi-independent right, secondly, through the method of traffic simulation analysis, it makes a preliminary discussion, and obtains the preliminary law about the applicability of various signal priority modes under semi-independent road right. Thirdly, on the basis of preliminary simulation analysis of intersection and review of present situation analysis and data envelope method, a multi-index evaluation method combining AHP and data envelope is proposed. In this paper, several scenarios are designed, which are composed of different values of multiple factors, and the simulation results are evaluated and analyzed by using the multi-index evaluation method of fusion hierarchy analysis and data envelopment. The single and comprehensive effects of various influencing factors on the intersection operation under the right of semi-independent tram are obtained. Specifically, the main contents and conclusions are as follows: 1) three basic methods of signal priority in intersection tram and their realization methods are expounded, and the applicability of three signal priority schemes, passive priority, active priority and real-time priority, is analyzed qualitatively. At the same time, the difference between upstream and downstream stopping schemes of tram is analyzed under the condition of different signal priority mode. 2) aiming at the applicability evaluation of signal priority, a multi-index evaluation method based on hierarchical analysis and data envelope is proposed. This method can not only overcome the uncertainty of judgment result caused by subjective judgment in AHP, but also give full play to the advantage of AHP in establishing evaluation hierarchy system and promoting multi-index fusion. This method is suitable for evaluating the operation efficiency of tram intersection under semi-independent right. 3) it is pointed out that the five main factors affecting the operation effect of intersections are: the signal priority mode of tram, the stop mode of tram intersection, The average lane flow ratio of intersecting road and tram (intersecting road flow ratio), tram running speed and road traffic speed are designed, 288 different combination simulation scenarios are designed. The simulation results are analyzed by the multi-index evaluation method of fusion hierarchy analysis and data envelope, and the operating benefit value of each scheme is evaluated according to the conflict security and service level. Based on this, the paper analyzes the influence of all factors on the intersection operation under semi-independent right.
