【摘要】：城市交通拥堵问题由来已久,一直是交通领域广泛关注的焦点,随着计算机技术和通讯技术的发展,交通设施的完善,智能化交通应运而生,获取各类交通信息的途径也越来越广泛。交通信息对居民出行行为有着巨大的影响,通信技术的不断成熟使得人们对于交通信息的需求也越来越强,基于目前的居民出行行为越来越复杂,已有的交通诱导系统虽然能在一定程度上通过引导驾驶员的出行路线,合理分配调度整个路网上的车辆,但由于目前的交通环境复杂,仅仅依靠交通诱导系统是不够的。因此,应站在更高的战略角度,从诱导控制策略着手,以各类交通方式组成的出行链为研究对象,探究在动静态交通诱导信息服务的作用下的联动诱导控制策略,这对于智能交通系统的建设发展具有更加深刻的指导意义。第一、首先通过对出行链、交通诱导系统进行分析指明缓解交通问题的有效途径是对诱导控制策略进行研究。第二、通过国内外研究现状,结合现有关于出行链的研究和出行行为的探索,对各类诱导信息下对出行链的影响机制给予分析。第三、通过对出行链的特征进行分析,给出出行链的不同类别,并将在动静态交通信息下的出行动态选择过程归结为多阶段决策过程,基于最优化理论,运用动态规划的方法对出行链中出行过程的选择机理进行研究,找出其内在的关系并用数学模型进行标定,建立选择最优出行链的计算方法。第四、通过对道路上已有的各类交通信息发布需求进行分析,对出行前和出行中的交通信息需求进行系统的分类,并从道路使用者和交通管理者的角度阐述交通信息发布需求和相应的管理对策。接着对对道路动静态诱导信息标志所涵盖的内容进行全面的分析界定,最后将动静态诱导信息进行整合并发布。第五,结合现有的交通诱导系统和交通控制系统,将两者联系起来,提出诱导基于动静态诱导信息下的控制策略的框架和诱导控制策略内容的设计。本文建立的分析框架和策略的具体设计对研究诱导控制策略的评价手段开辟了新的道路。
[Abstract]:The problem of urban traffic congestion has a long history and has been the focus of extensive attention in the field of transportation. With the development of computer technology and communication technology, the improvement of traffic facilities, intelligent traffic emerged as the times require. Access to all kinds of traffic information is becoming more and more extensive. Traffic information has a great impact on the travel behavior of residents. With the continuous development of communication technology, the demand for traffic information is becoming stronger and stronger, and the current travel behavior of residents is becoming more and more complex. Although the existing traffic guidance system can reasonably distribute and dispatch the vehicles on the whole road network to a certain extent by guiding the driver's route, it is not enough to rely on the traffic guidance system only because of the complexity of the current traffic environment. Therefore, from a higher strategic point of view, we should start with the induction control strategy, take the trip chain composed of various traffic modes as the research object, and explore the linkage guidance control strategy under the action of the dynamic and static traffic guidance information service. This has more profound guiding significance for the construction and development of intelligent transportation system. Firstly, through the analysis of the trip chain and the traffic guidance system, it is pointed out that the effective way to alleviate the traffic problem is to study the induction control strategy. Secondly, through the domestic and international research status, combined with the existing research on trip chain and trip behavior exploration, the paper analyzes the influence mechanism of trip chain under all kinds of induced information. Thirdly, by analyzing the characteristics of the trip chain, the different types of the trip chain are given, and the dynamic selection process under the dynamic and static traffic information is reduced to a multi-stage decision-making process, which is based on the optimization theory. The dynamic programming method is used to study the selection mechanism of the trip process in the trip chain. The inherent relationship is found out and the mathematical model is used to calibrate the calculation method of selecting the optimal trip chain. Fourth, through the analysis of all kinds of traffic information needs on the road, the traffic information needs before and during travel are classified systematically. From the point of view of road users and traffic managers, this paper expounds the demand of traffic information release and the corresponding management countermeasures. Then, the contents of the information sign of road dynamic and static guidance are analyzed and defined, and the dynamic and static guidance information is integrated and published. Fifthly, combining the existing traffic guidance system and traffic control system, the paper puts forward the framework of the guidance control strategy based on the dynamic and static guidance information and the design of the guidance control strategy content. The analytical framework and the specific design of the strategy provided in this paper have opened a new way for the study of the evaluation methods of the induced control strategy.
