【摘要】：随着我国城市对环境的要求,以及构建多方式综合交通体系的需要,很多城市开始大力发展公共交通。环境友好型的现代有轨电车交通系统是一种环保、高效的中低运量城市轨道交通系统,因其具有建设成本低、建设周期短、运行速度快、舒适度高、节能节地等突出优点,在国外发达城市已经得到大量应用。我国现代有轨电车刚刚处于起步阶段,由于我国的交通环境复杂,无法直接应用国外先进的经验,导致在运营管理过程中存在平交道口通行效率低、安全隐患多等严峻问题。现代有轨电车系统是后加入的地面公共交通,有轨电车的加入会改变原来的道路交通规划、管理、控制,会对社会交通造成干扰,合理的交通信号控制将可以提高整体交通运行效率。本文从智能交通控制的角度出发,依托北京市科技计划课题《现代有轨电车运行协同智能管控系统研究》,以分析现代有轨电车特征为基础,展开现代有轨电车信号优先控制方法的研究,实现有轨电车的预期运营效果,保障有轨电车的运营安全。课题首先分析了现代有轨电车的基本车辆技术特征、运行状态、调度规律以及站点设置等客观因素,研究了现代有轨电车在交叉路口与社会车流的冲突关系以及有轨电车的加入对交通信号控制的影响,并根据有轨电车在交叉口不同的行驶状态,得出了现代有轨电车相位最小绿灯时间计算方法。结合现代有轨电车车辆的优先等级和控制要求,重点研究现代有轨电车车辆在平交道口下的被动优先、绝对优先、完全优先、部分优先等各种优先策略,并以典型四相位信号控制为例,建立了现代有轨电车的交叉口控制模型。在现代有轨电车运行特性的基础上通过列车定位技术及交通流检测技术获取列车实时定位信息及交通流信息,结合有轨电车行车计划,基于有轨电车安全保障技术,建立了有轨电车的停车线到达时间预测模型,提出现代有轨电车协同优先控制算法,从区域控制的角度实现信号优先,降低信号优先对区域交通的影响,实现有轨电车的线路协同优先通行,提升有轨电车及道路交通的整体运营效益。本文最后以沈阳浑南新区现代有轨电车线路为分析案例,选取部分区间进行仿真实验。对比分析实施信号优先前后,有轨电车以及社会车流的旅行速度、停车延误等。
[Abstract]:With the environmental requirements of Chinese cities and the need to build a multi-mode integrated transportation system, many cities began to vigorously develop public transport. The environment-friendly modern tram transportation system is an environmental protection. High efficiency urban rail transit system with low cost, short construction period, fast running speed, high comfort, energy saving and land saving advantages. The modern tram in our country is just in its infancy, because the traffic environment of our country is complex, it is impossible to apply the advanced experience of foreign countries directly. In the process of operation and management there are serious problems such as low efficiency of level crossing and many hidden safety problems. The modern tram system is the ground public transportation after joining. The introduction of trams will change the original road traffic planning, management and control, and will interfere with social traffic. Reasonable traffic signal control will improve the overall traffic efficiency. From the perspective of intelligent traffic control, this paper relies on the Beijing science and technology project "modern tram operation cooperative intelligent management and control system research". Based on the analysis of the characteristics of modern tram, the research on signal priority control method of modern tram is carried out to realize the expected operation effect of tram. First of all, the paper analyzes the basic vehicle technical characteristics, running state, dispatching law and station setting of modern tram. This paper studies the conflict relationship between modern tram at intersection and social traffic flow and the influence of tram on traffic signal control, and according to the different driving state of tram at intersection. The calculation method of phase minimum green time of modern tram is obtained. Combined with the priority grade and control requirement of modern tram vehicle, the passive priority of modern tram vehicle under horizontal crossing is studied emphatically. Absolute priority, complete priority, partial priority and other priority strategies, and take typical four-phase signal control as an example. The intersection control model of modern tram is established. Based on the operation characteristics of modern tram, the real-time location information and traffic flow information are obtained by train positioning technology and traffic flow detection technology. Based on the tram safety and security technology, a model for predicting the arrival time of the tram stop line is established, and a collaborative priority control algorithm for modern tram is proposed. From the point of view of regional control, signal priority is realized, and the influence of signal priority on regional traffic is reduced. Finally, taking the modern tram line in Hunnan New District of Shenyang as an analysis case, selected parts of the section to carry out simulation experiments, and compared the implementation of signal before and after priority. Trams and social traffic travel speed, parking delays and so on.
