【摘要】：随着国家城镇化进程的不断推进,城市中交通供需失衡的问题也日益突显。城市中部分地区由于道路资源分配不均而引发的诸多交通问题,表明在这些地区实行传统道路的双向通行模式已经不能较好得适应人们的出行需求。单向交通作为一种城市道路交通流的组织形式,在大量的实践中表现了其所具有的独特优势,同时也产生了一些弊端。如何合理有效得分析单向交通的实施效益及评价方案效果对成功的单行组织十分重要。本文从单向交通的特性分析入手,分析了单向交通的实施对相应路段、相交道路及周围路网所带来的效益提升及其所产生的不利影响。在现有的影响区域方法总结的基础上对单向交通的影响区域进行了定义并进行了合理的解释说明,同时对单向交通对交叉口效益的改善及其所产生了的绕行影响提供了新的分析方法。对评价理论进行了较为系统性的总结,按照评价过程的系统性、科学性、可操作性等相关原则,根据单向交通的特性分析结果及评价的需要建立了新的单向交通实施效益的评价指标体系,并对指标选取的意义及量化方法进行了说明。通过对指标的归类分析,提高了评价结果的系统性和科学性。通过分析现有评价方法的原理、优缺点及其适用性,依照所建立的指标体系的结构特点等提出了基于主成分分析方法(PCA)的主客观赋权相结合的单向交通实施效益评价模型。对模型的相关理论进行了阐述,同时引入有效性检验理论,对评价结果进行有效性检验,并将评价结果进行分类,为单行方案的改善和实施提供相应的决策依据。最后,应用评价模型对南京市部分单行路段进行效益评价,通过现状交通调查获取相应数据并进行了模型的实例论证,得到了所选评价对象的评价结论。针对评价过程中所产生的问题提出行了相应的解决措施及建议,以改善南京市单向交通的实施效果。
[Abstract]:With the development of urbanization, the imbalance of traffic supply and demand in cities is becoming more and more prominent. Many traffic problems caused by the uneven distribution of road resources in some parts of the city show that the traditional two-way traffic mode in these areas has not been able to adapt to the travel needs of people. One-way traffic, as a form of organizing urban road traffic flow, has shown its unique advantages in a large number of practices, and has also produced some drawbacks. How to reasonably and effectively analyze the effect of one-way traffic and evaluate the effect of the scheme is very important to the successful organization. Starting with the analysis of the characteristics of one-way traffic, this paper analyzes the benefits and adverse effects of one-way traffic on the corresponding road sections, intersecting roads and surrounding road networks. On the basis of summing up the existing methods of influence area, the paper defines the influence area of one-way traffic and explains it reasonably. At the same time, it provides a new analysis method for the improvement of the efficiency and the bypass effect of the one-way traffic on the intersection. The evaluation theory is summarized systematically, according to the systematic, scientific, operable and other relevant principles of the evaluation process. According to the analysis results of one-way traffic characteristics and the needs of evaluation, a new evaluation index system of one-way traffic performance is established, and the significance and quantitative method of index selection are explained. The systematic and scientific evaluation results are improved through the classification and analysis of the indicators. By analyzing the principles, advantages and disadvantages and applicability of the existing evaluation methods, and according to the structural characteristics of the established index system, this paper puts forward a one-way traffic implementation benefit evaluation model based on the subjective and objective weights combined with the principal component analysis (PCA) method. At the same time, the validity test theory is introduced to test the effectiveness of the evaluation results, and the evaluation results are classified to provide the corresponding decision basis for the improvement and implementation of one-line schemes. Finally, the evaluation model is applied to evaluate the benefit of part of the single-lane road in Nanjing. The corresponding data are obtained through the current traffic survey, and the model is demonstrated by an example, and the evaluation conclusions of the selected evaluation objects are obtained. In order to improve the effect of one-way traffic in Nanjing, the corresponding measures and suggestions are put forward to solve the problems in the evaluation process.
