城市道路网容量节点路段化分析方法研究
|
摘要
道路网容量是科学合理的评价道路网规划设计方案的重要指标,是研究改善交通组织和城市道路交通管理的重要参数。形成一套实用准确的分析道路网交通供给量大小的理论方法,确定一定状态下的道路网容量,对于分析城市交通供需状态具有重要意义。国内外研究实践表明,在城市交通供需平衡原则下,开展对城市道路网规划设计的评价工作和指导道路网改造方案实施,对于完善交通规划方案、提高道路网改造实施质量具有重要而积极的促进作用。
在借鉴国内外相关研究成果基础之上,针对现有道路网容量分析方法没有合理考虑节点对道路网容量影响的问题,探讨了道路网容量节点路段化分析方法。根据道路网容量分类,本文将一定路网服务水平时,实际道路交通环境下,单位时间内道路网允许通行的最大车辆数作为研究目标。
通过分析节点及路段容量的主要影响因素,简化了不同类型节点和路段容量模型,并对节点入口扩宽及道路不同横断面型式进行修正,得到了节点等效容量。基于道路网平面赋权连通图,论文运用数学方法结合模型构架与求解的方式,构建了城市道路网容量等效模型。以东莞市道路网为例证,将模型结果与时空消耗法理论进行了对比分析,表明模型在计算精度及实用性方面达到了预期目标。采用路网平均饱和度作为路网服务水平分级指标,给出了一定服务水平时的实际道路网容量。
道路网容量节点路段化分析方法的应用研究主要分为3个方面:采用路网负荷度系数评价道路网规模,并选取道路网平均饱和度等10个指标,建立了道路网模糊评价指标体系。基于节点等效容量,改进了道路阻抗分析方法,并将其引入到道路网容量限制—多路径—增量加载交通分配法中。在道路网改造方面,根据不同等级路网容量,给出了不同等级路网的合理长度;采用AHP法给出了影响节点势能的各指标权重,并引入改进的道路阻抗函数,构建了节点合理间距模型。
Road network is the carrier of urban transport, road network capacity is an important parameter for scientifically and legitimately road network planning and design, improving traffic organization and management. How to form the convenient and applied and accurate theoretical approach for analyzing the size of traffic supply of the road network,which has always been of concern to the community, especially for the urban transport planning and management department. Domestic and international research and practice show that, according to city traffic demand forecast, under the principle of supply and demand balance,it is promotion to determine specific capacity of the certain road network, for carrying out evaluation of the urban road network planning and design, guidance on the implementation of the road network rehabilitation programs, improving the transportation planning program and the quality of road network rebuilding.
Node Equivalent of urban road network capacity analysis method is introduced to determine a certain state of network capacity conveniently and practically. Through research on he road network capacity theory, to improve of China's vast urban transport planning, reduce traffic congestion and achieve sustainable development of cities, to provide a reference basis and reference.
Based on research from home and abroad, analysis of the existing road network capacity has not fully considered the affecting of nodes on the road network capacity. Of the actual road traffic environment, in a certain service level, within the road network in unit time the maximum number of vehicles allowed to pass.It is mainly related to different types of node capacity, node entry amendments broaden the circumstances, sections of different cross section of road capacity and type of correction. Mathematical methods in theoretical models framework and other methods and solutions are used in this paper, Dongguan City, for the example, Model results will be compared with the theoretical analysis of space-time consumption, hows that the model precision and practicality to achieve the expected goal.
Road network capacity equivalent model of applied research is divided into three areas: Select the road network, the average saturation of 10 indicators of road network to establish fuzzy evaluation index system. The introduction of node impedance to improve the capacity of road network traffic distribution method. Transforming the road network, according to the principle of supply and demand balance, determine the proportion of grade-level distribution; Signalized intersection at the entrance to a reasonable number of lanes and lane widening to set the length to enhance the capacity of the node; The introduction of node potential theory, to address the control of the domain node cross sections caused by the increase in resistance, proposed method for determining the appropriate distance between nodes. View of the imperfections of this research, the theory models and methods, in-depth research to explore application of the model are the focus of future research.
