【摘要】：交通问题一直困扰着各个大中型城市,尤其随着经济的快速发展和机动车保有量的增加,交通拥挤问题变得越来越严重。城市道路交通问题己经严重影响了社会经济的健康发展,那么,缓解道路交通拥挤已经成为了刻不容缓、亟待解决的问题。这也是政府部门和交通研究者必须履行的职责。因此,本文对交通拥挤收费进行研究,对西安某路段进行拥挤道路双层收费模型的建立,通过对拥挤双层收费模型的研究以及仿真并结合交通需求管理的优点,有效促进交通资源的利用,提高交通效率。本文的主要内容如下:首先,本文对交通拥挤收费进行了概述,分别介绍交通拥挤收费的概念理论以及拥挤收费的相关定价理论,其次对道路拥挤收费的各种分类方法进行介绍,并对国内外道路拥挤收费的理论研究成果进行概述,也介绍了拥挤收费的模型理论。然后以新加坡、斯德哥尔摩、伦敦、香港等城市为例,简介城市道路拥挤收费政策的国内外应用现状实施结果。其次,本文对静态和动态的交通拥挤收费模型的建立分别进行介绍,运用改进的Logit算法对交通流量进行分配,完善现有的动态交通分配模型,以居民出行路径选择的路线为数据,对拥挤收费区域路段做界定。采用双层收费模型,上层模型用来确定收费策略,下层满足出行者的路径选择。最后,对建立好的模型用VISSIM进行仿真,将拥挤收费的应用展现出来。先利用拥挤收费模型建立虚拟路网,对各参数进行设置,然后进行多次仿真,对道路拥挤的实施效果进行综合分析并加以改进,对拥挤路段进行收费的定价。最终根据建模以及仿真结果,以具体图表形式呈现,说明了实施拥挤收费策略对于缓解交通拥挤有着重要的意义,达到了有效缓解交通拥挤的目的。
[Abstract]:Traffic problems have been puzzling large and medium-sized cities, especially with the rapid development of economy and the increase of vehicle ownership, traffic congestion has become more and more serious. The problem of urban road traffic has seriously affected the healthy development of social economy, so alleviating road traffic congestion has become an urgent problem to be solved. This is also the responsibility of government departments and traffic researchers. Therefore, this paper studies traffic congestion charges, builds a two-layer toll model for a section of Xi'an road congestion, through the study of congestion double-layer toll model and simulation, combined with the advantages of traffic demand management. Effectively promote the use of traffic resources, improve traffic efficiency. The main contents of this paper are as follows: firstly, this paper gives an overview of traffic congestion charges, introduces the concept theory of traffic congestion charges and the related pricing theory of congestion charges. Secondly, it introduces the classification methods of road congestion pricing, summarizes the theoretical research results of road congestion pricing at home and abroad, and also introduces the model theory of congestion pricing. Then take Singapore, Stockholm, London, Hong Kong and other cities as examples, introduce the implementation results of the domestic and international application of urban road congestion pricing policy. Secondly, this paper introduces the establishment of static and dynamic traffic congestion toll models, and uses the improved Logit algorithm to allocate traffic flow, and improves the existing dynamic traffic allocation model. Taking the route chosen by residents as data, the section of congestion toll area is defined. The upper layer model is used to determine the charging strategy, and the lower layer satisfies the route choice of the traveler. Finally, the established model is simulated with VISSIM to show the application of congestion charge. Firstly, the virtual road network is established by using congestion toll model, then the parameters are set up, and then the simulation is carried out for several times, and the comprehensive analysis and improvement of the implementation effect of congestion are carried out, and the pricing of toll collection on congested sections is carried out. Finally according to the modeling and simulation results presented in the form of specific charts the implementation of congestion charging strategy for reducing traffic congestion has an important significance to achieve the purpose of reducing traffic congestion.
