【摘要】：随着我国国民经济的高速发展和城市化进程的加快，机动车保有量和道路交通量急剧增加，城市交通基础设施建设速度远远跟不上快速增长的交通需求，城市交通供需矛盾十分尖锐。仅仅依靠于传统的交通管理方式，单从道路和车辆的角度考虑，很难解决不断恶化的交通堵塞、事故频发、环境污染、能源短缺等世界各国面临的共同问题。基于车车、车路信息交互建立人、车、路一体的交通运输系统，对提高交通运输系统的效率和安全性，实现交通系统的可持续性发展具有十分重要的意义。车路协同技术是当今国际智能交通领域的前沿技术，是城市交通问题的有效解决方案。车路协同系统运用先进的全时空动态交通信息采集、融合技术，通过全方位实施车/车、车/路动态实时信息交互进行车辆主动安全控制和交通协同管理，是一个涉及多因素、多层次复杂关系的大规模实时分布式系统。城市道路网中的交通干线是城市交通运输的大动脉，它们经常要承受巨大的交通压力，因此努力提高干线的控制效果对改善整个城市交通状况具有重要意义。开展车路协同环境下干线交叉口信号协调控制技术研究，有利于为改善我国道路交通安全和效率提供技术储备。因此，本论文在分析国内外车路协同系统和交通信号控制系统的基础上，分析车路协同环境下驾驶员行为特性，建立面向车路协同环境的城市干线交通流模型；解析车路协同环境下交通信号控制系统与交通流之间的交互作用机制，建立基于车路协同环境的干线交叉口信号控制方法和模型，并开展交通仿真实验测试和验证，为开发下一代交通信号控制系统奠定基础，具有重要的理论意义和实用价值。本论文在研究车路协同技术体系框架和城市干线交叉口信号协调控制基本方法的基础上，提出了一种车路协同环境下干线交叉口信号协调控制模型，并对车路协同环境下车辆速度引导模型进行了研究。第1章回顾了国内外关于车路协同系统和城市交通信号控制的研究现状，针对当前信号控制方法存在的不足，提出了利用车路协同技术，提高交通信号控制的重要性，进而引出本文的研究内容以及具体章节安排。第2章详细介绍了车路协同系统技术体系框架。第3章分析了干线协调控制的基本理论和常用干线协调控制模型。第4章首先分析了车路协同环境下交叉信号控制系统框架，研究了道路交叉口车辆运行过程、并给出了车路协同环境下干线交叉口信号控制流程，建立了车路协同环境DSDS(Dynamic Speed guidance and Dynamic Signal timing)策略下的干线交叉口协调控制模型，并分析了车路协同环境下单交叉口单车和多车速度引导模型。第5章构建了车路协同信号控制实验系统，并对各个模块的设计流程进行了详细的论述。并以4个交叉口为实验对象，仿真实验表明，，本文建立的交通信号控制方法优于传统定时控制和MAXBAND干线协调控制方法。本文对车路协同环境下干线交叉口信号协调控制方法进行了深入的研究，研究结果表明本文建立的交通信号控制方法优于传统定时控制和MAXBAND干线协调控制方法。然而本文建立的基于车辆延误和停车次数的信号控制模型没有考虑车辆之间的个体差异性，并且未考虑行人和非机动车的对干线交叉口的影响，这与国内城市交叉口机非混行的现状在一定程度上不符合。因此车路协同环境下混合交通流信号控制方法有待进一步分析。
[Abstract]:With the rapid development of China's national economy and the acceleration of urbanization process, the quantity of motor vehicles and the traffic volume of road increase rapidly. The speed of urban traffic infrastructure construction is far from the rapid growth of traffic demand. The contradiction between supply and demand of urban traffic is very sharp. Only the traditional way of traffic management is only from the road and vehicle. From the angle of view, it is difficult to solve the common problems faced by countries all over the world, such as worsening traffic jam, frequent accidents, environmental pollution and energy shortage.
Based on car, vehicle road information interaction to establish human, vehicle and road integrated transportation system is of great significance for improving the efficiency and safety of transportation system and realizing the sustainable development of traffic system. Vehicle road coordination technology is the frontier technology in the field of international intelligent transportation and is an effective solution to urban traffic problems. Vehicle road cooperative system is a large-scale real-time distributed system involving multiple factors and multi-level complex relationships, using advanced full time and dynamic traffic information collection and fusion technology, through the full implementation of vehicle / car, vehicle / road dynamic real-time information interaction for vehicle active safety control and traffic coordination management.
The main traffic arteries in urban road network are the big arteries of urban traffic and transportation, and they often have to bear huge traffic pressure. Therefore, it is of great significance to improve the control effect of the trunk line to improve the whole urban traffic condition. The road traffic safety and efficiency provide technical reserve. Therefore, on the basis of analyzing the vehicle road coordination system and traffic signal control system at home and abroad, this paper analyzes the driver behavior characteristics under the cooperative environment of vehicle road, establishes the urban trunk traffic flow model facing the coordinated environment of vehicle road, and analyzes the traffic signal control system under the cooperative environment of the vehicle road. The interaction mechanism between the traffic flow and the traffic flow is used to establish the signal control method and model of the trunk intersection based on the vehicle road coordination environment, and carry out the test and verification of the traffic simulation experiment. It lays the foundation for the development of the next generation traffic signal control system. It has important theoretical significance and practical value.
In this paper, on the basis of studying the framework of vehicle road coordination technology system and the basic method of signal coordination control in the intersection of urban trunk lines, this paper presents a signal coordination control model of the trunk intersection under the coordinated environment of vehicle road, and studies the speed guide model of vehicle under the coordinated environment of vehicle road.
The first chapter reviews the research status of vehicle road coordination system and urban traffic signal control at home and abroad. In view of the shortage of current signal control methods, it puts forward the importance of using vehicle road coordination technology to improve traffic signal control, and then leads to the research content and specific chapters in this paper.
The second chapter introduces the technical framework of vehicle road collaboration system in detail.
The third chapter analyzes the basic theory of trunk coordinated control and the commonly used trunk coordination control model.
The fourth chapter first analyzes the frame of cross signal control system under the cooperative environment of vehicle road, studies the running process of the road intersection, and gives the signal control process of the trunk intersection under the cooperative environment of the vehicle road, and establishes the coordination of the trunk intersection under the DSDS (Dynamic Speed guidance and Dynamic Signal timing) strategy. The control model and the speed guidance model for single intersection and multiple vehicles at single intersection are analyzed.
The fifth chapter constructs the vehicle road cooperative signal control experiment system, and discusses the design process of each module in detail. The experiment shows that the traffic signal control method established in this paper is superior to the traditional timing control and the MAXBAND trunk line coordination control method.
This paper makes an in-depth study on the signal coordination control method of the trunk intersection under the cooperative environment of the vehicle road. The results show that the traffic signal control method established in this paper is superior to the traditional timing control and the MAXBAND trunk line coordination control method. However, the signal control model based on the vehicle delay and the number of stopping times is not considered in this paper. The individual difference between vehicles does not take into account the impact of pedestrians and non motor vehicles on the intersections of the trunk lines. This is not consistent with the current situation of the non mixing of the domestic urban intersections. Therefore, the mixed traffic signal control method under the environment of vehicle road coordination needs to be further analyzed.
