【摘要】：在多种城市形态中,多中心、组团式布局城市有着明显的交通优势,被认为是当今大城市主流的发展形态。组团城市中,大多数的交通出行都可以在组团内部完成,城市中的交通流被分散到了各级组团之中,从而降低了城市中心区的道路交通压力,确保了城市道路交通的高效运行。然而伴随着城市机动化的快速发展,汽车保有量不断增加,道路交通量也日益增大,组团路网交通拥堵问题越来越突出,组团式布局模式交通优势地位不再明显。如果能够准确衡量组团路网服务水平,把握组团路网交通运行状况,将有利于交通管理人员制定合理的交通管理措施,从而达到缓解组团路网交通拥堵的目的。评价指标的选取、评价模型的建立以及分级标准的确定是服务水平评价问题的三大基本要素。本文将城市组团路网特性与服务水平评价问题的这三大基本要素相结合,展开了对于城市组团路网服务水平评价问题的研究。全文的研究工作主要体现在以下几个方面:①从不同角度剖析了城市组团的路网特性。本文从道路组成与路网功能的角度对城市组团路网的道路特性进行了分析,指出了组成城市组团路网的两大交通网,为城市组团路网服务水平评价模型的建立奠定了基础。然后从宏观和微观两个不同角度对城市组团路网的交通流特性进行了分析,为城市组团路网服务水平评价指标的选取做了铺垫。②选取了更能准确衡量组团路网服务水平的评价指标。以往对于服务水平的评价研究大多是从微观路段(或交叉口)角度进行分析,但是这并不完全适用于路网服务水平的评价。本文从与组团路网的运行状况息息相关的各级组成道路出发进行了组团路网服务水平评价指标的选取,并从组团路网结构组成特性出发,建立了涵盖微观、中观、宏观三个不同层次的组团路网服务水平评价指标体系。③建立了城市组团路网服务水平的分级标准。本文从服务水平评价问题的模糊性角度出发,运用模糊聚类理论,通过对大量数据进行聚类分析来确定两个新评价指标的分级标准。④建立了组团路网服务水平评价的分层次结构模型。本文以组团路网服务水平评价指标体系为基础,将模糊综合评价法与聚类分析法、层次分析法相结合,按照微观路段、中观道路、宏观路网的顺序对城市组团路网服务水平进行了逐层评价。
[Abstract]:In a variety of urban forms, multi-center, group layout of the city has obvious traffic advantages, is considered to be the mainstream of the development of large cities. Most of the traffic travel can be completed within the group, and the traffic flow in the city is scattered to all levels of the group, thus reducing the road traffic pressure in the central area of the city. To ensure the efficient operation of urban road traffic. However, with the rapid development of urban motorization, the number of vehicles is increasing, the traffic volume is also increasing, and the traffic congestion problem of group road network is becoming more and more prominent. If we can accurately measure the service level of the group road network and grasp the traffic operation status of the group road network, it will be helpful for traffic management personnel to formulate reasonable traffic management measures. In order to alleviate the traffic congestion of the group road network, the selection of evaluation indicators. The establishment of evaluation model and the determination of grading criteria are the three basic elements of service level evaluation. This paper combines the characteristics of urban group road network with the three basic elements of service level evaluation. The research on the evaluation of the service level of urban group road network is carried out. The research work of this paper is mainly reflected in the following aspects:. The main contents are as follows: 1. This paper analyzes the road characteristics of urban group road network from the point of view of road composition and road network function. The paper points out the two traffic networks that make up the urban group network. It lays a foundation for the establishment of service level evaluation model of urban regiment road network. Then the traffic flow characteristics of urban regiment road network are analyzed from two different angles: macro and micro. This paper paves the way for the selection of service level evaluation index of urban regiment road network, and selects the evaluation index that can more accurately measure the service level of urban regiment road network. In the past, most of the research on service level evaluation was based on microscopic sections (2). Or intersection) angle analysis. However, this is not fully applicable to the evaluation of the service level of the network. This paper begins with the selection of evaluation indicators of the service level of the group road network, which is closely related to the operation of the group road network at all levels. Based on the characteristics of the road network structure, the microscopic and mesoscopic systems are established. Three different levels of macroscopic evaluation index system of service level of group road network. 3. The classification standard of service level of urban group road network is established. This paper starts from the fuzziness of service level evaluation problem. Using fuzzy clustering theory. Based on the cluster analysis of a large number of data, the hierarchical structure model of service level evaluation of group road network is established by determining the classification standard of two new evaluation indexes, and the evaluation index system of service level of group road network is taken as the index system in this paper. Basic. By combining fuzzy comprehensive evaluation method with cluster analysis method and analytic hierarchy process, the service level of urban regiment road network is evaluated layer by layer according to the order of micro section, meso road and macro road network.
