【摘要】：汽车尾号限行已经成为很多城市缓解交通拥堵的有效措施之一,针对这种现实情况,本文研究了尾号限行情况下交通网络配流模型及相关应用。第一章,介绍了尾号限行问题的研究背景及相关研究进展,概述了当前的交通网络按车牌尾号限行的方法,并阐述了尾号限行问题所要用到的一些基本原理和方法。接着,第二章给出了尾号限行条件下交通均衡条件,并将尾号限行情况下交通网络配流模型归结为一个约束优化问题,通过分析该问题解的性质,给出了相关的等价性证明和求解算法。在该模型的基础之上,第三章引入限行条件下交通网络流量备用能力的概念,给出了尾号限行情况下交通网络备用能力优化的双层规划模型,该模型上层问题以最大化网络备用能力为目标函数,交通网络限行方案为决策变量;下层问题为尾号限行情况下交通网络配流模型,并设计启发式算法求解该双层规划模型。算例结果表明,对某些路段实施尾号限行,可以提高整个交通网络的通行能力,或者减少交通拥堵。第四章,通过对网络拓扑结构的分析,我们给出了一种确定网络中关键路段方法,将该方法用于尾号限行情况下交通网络备用能力优化的双层规划模型,可以排除明显不能实施尾号限行的路段,帮助缩小搜索范围,从而降低了运算量,提高了计算效率。最后,在第五章,给出了本文的结论和展望。
[Abstract]:The vehicle tail number restriction has become one of the effective measures to alleviate traffic congestion in many cities. In view of this practical situation, this paper studies the traffic network assignment model and its related applications. In the first chapter, the research background and related research progress of the trailing number limit problem are introduced, and the methods of the current traffic network according to the vehicle license plate end number limit are summarized, and some basic principles and methods used in the trailing number limit problem are expounded. Then, in the second chapter, the traffic equilibrium condition under the condition of the trailing number limit is given, and the traffic network assignment model under the condition of the trailing number limit is reduced to a constrained optimization problem, and the properties of the solution of the problem are analyzed. The equivalence proof and algorithm are given. On the basis of the model, in chapter 3, the concept of traffic network reserve capacity under the condition of traffic limit is introduced, and a bilevel programming model for optimization of traffic network reserve capacity under the condition of traffic limit is given. The upper layer of the model takes maximizing the backup capacity of the network as the objective function, the traffic network limit scheme is the decision variable, and the lower layer problem is the traffic network assignment model with the trailing number limit, and a heuristic algorithm is designed to solve the bilevel programming model. The results of numerical examples show that the traffic capacity of the whole traffic network can be improved or traffic congestion can be reduced by implementing the trailing limit on some sections of the road. In chapter 4, through the analysis of the network topology, we present a method to determine the key sections in the network, which is applied to the two-layer programming model of the optimization of the backup capacity of the traffic network under the condition of the trailing number limit. It can eliminate the section that can not carry out the trailing number limit obviously, and help to narrow the search range, thus reducing the calculation amount and improving the calculation efficiency. Finally, in the fifth chapter, the conclusion and prospect of this paper are given.
