【摘要】：有轨电车作为一种很早就诞生的交通方式,经历了昌盛到衰落的过程。随着环境污染、道路拥堵、能源短缺等问题的日益严重,有轨电车再次进入了大众的视野,走上了复兴之路。交叉口是城市交通的重要环节,为了提高有轨电车在交叉口的通过效率,需要在交叉口实现优先策略,让有轨电车优先通过。首先,本文介绍了有轨电车的信号系统结构,对各个子系统的结构和功能进行了简单的说明。其次,分析了有轨电车交叉口的优先策略,包括绝对优先、相对优先和无优先策略,对这三种优先策略的适用性和优缺点进行了对比,建立了交叉口数学模型,完成了相对优先策略的算法设计。然后,详细介绍了如何在有轨电车调度指挥系统中应用优先策略,对其中的几个关键问题进行了分析,包括列车位置检测、优先请求发送、优先请求处理和信号机控制。另外还介绍了系统的方案设计,包括界面显示、系统通信和信号控制方案。最后,分析了有轨电车在交叉口请求优先通过的全过程,在实验室仿真平台中成功实现了交叉口相对优先策略。本文初步完成了有轨电车信号系统和交通信号系统的接口设计,分析了有轨电车在交叉口请求优先通过的信号处理流程,并在实验室仿真平台中实现了相对优先策略,为有轨电车交叉口的信号优先控制提供了一定的参考价值。
[Abstract]:Tram, as a kind of traffic mode born early, has experienced the process of prosperity and decline. With the environmental pollution, road congestion, energy shortage and other increasingly serious problems, trams have once again entered the public view, and embarked on the road of revival. Intersection is an important part of urban traffic. In order to improve the efficiency of tram passing through the intersection, priority strategy should be realized at the intersection, and the tram should pass first. Firstly, this paper introduces the signal system structure of tram, and gives a brief description of the structure and function of each subsystem. Secondly, the priority strategy of tram intersection is analyzed, including absolute priority strategy, relative priority strategy and no priority strategy. The applicability, advantages and disadvantages of these three priority strategies are compared, and the mathematical model of intersection is established. The algorithm design of relative priority strategy is completed. Then, how to apply priority strategy to train dispatching command system is introduced in detail, and some key problems are analyzed, including train position detection, priority request sending, priority request processing and signal control. In addition, the design of the system is introduced, including interface display, system communication and signal control. Finally, the whole process of the tram request priority passing at the intersection is analyzed, and the relative priority strategy of the intersection is successfully realized in the laboratory simulation platform. In this paper, the interface design of the tram signal system and the traffic signal system is preliminarily completed, and the signal processing flow of the tram request priority at the intersection is analyzed, and the relative priority strategy is realized in the laboratory simulation platform. It provides a certain reference value for the signal priority control of tram intersection.
