【摘要】 近年来,城市机动车保有量大幅增加,增长速度远远超过道路改扩建的速度,同时,城市经济快速发展所生成的交通需求远远大于城市特别是中心区域已有道路资源的供给能力。然而,城市中心区道路资源的有限性,以及近期内不可能无限度地增扩性,也就限制了城市中心区交通需求的过快增长。本文分析城市中心区基本特性入手,提出针对某一城市的中心区交通组织方案,为决策者提供理论支持依据。本文首先分析城市中心区的职能、用地结构和交通等三方面特性,指出中心区土地利用强度较高、容易产生局部或全区域的交通拥堵等特点。根据中心区交通组织原则,特别是最低可接受服务水平的原则,提出管理措施排优和基于拥堵范围进行交通组织管理的两种城市中心区交通组织的方法思想。结合交通组织的一般管理措施,提出中心区交通组织的方法步骤。利用可拓理论解决矛盾问题的思想,对中心区交通组织方案进行评价。在进行评价之前,首先对评价指标的选取进行科学系统的归纳总结,结合国内外相关论述,提出一套适用于城市中心区交通组织方案评价的指标体系。接下来根据可拓层次分析法构建中心区交通组织方案的评价思路,并对可拓理论关于中心区交通组织方案评价的适用性的进行描述。最后建立物元可拓评价模型,完成城市中心区交通组织方案评价的理论框架模型。以河南省商丘市城市中心区为实例研究对象,首先分析商丘市中心区路网现状、土地利用现状及交通现状。随后针对中心区存在的交通问题等提出一套适用于商丘市中心区的交通组织方案,并以商丘市中心区路网现状交通组织作为初始方案最为对比方案,运用交通规划软件TransCAD,分配路网交通流量,并取得各项评价指标的确切数值。最后运用物元可拓评价模型,通过确切的数值显示表明交通组织方案的可取性。更多还原

【Abstract】 During the last decades, the quantities of motor vehicles have increased a lot with a rapid increase speed which is far larger than that of the road expansion, and the requirement of transportation caused by the development of economy has exceeded the ability of supply. However, the limitation of the road resource, and the impossibility of unlimited growth have become the factors limiting the increase of traffic demand of the city center. Therefore, an optimized plan is proposed to the managers in this work.By analyzing the performance of function, the structure of land using, transportation of the center area of the city, the characteristics of higher intensity of land using and part or all prone to traffic jams are pointed out. A method of management scheduling priority and congestion optimization based on the range is brought out based on the rule of minimum acceptable level of service, and then the details are given considering the common.The plan of optimal traffic organization of the central area of program evaluation is evaluated with the theory of matter-element extension method. And before the evaluation, first of all, the selection of a scientific evaluation system must be summarized, and discourses at home and abroad, getting an excellent evaluation index system of traffic organization and optimization program. And then, the ideas of the evaluation of traffic organization and optimization program can be described according to the matter-element extension method. Finally, the matter-element extension model and downtown traffic organization and optimization program evaluation model are built.Taking the center area of Shangqiu, Henan as an example, first of all, the status of the central area road network and land use and transportation are analyzed. And then a program of traffic organization and optimization for Shangqiu is worked out, and the transportation flux is calculated with TransCAD. The results are compared with that of the current traffic organization and optimization. The results show that the plan in this work will lead to a nicer one.更多还原
