摘要
根据城市道路的实际使用功能与规划设计功能之间的吻合程度,提出了功能匹配度这一概念,并从路段交通量的方式分担、距离分布(短、中、长距离出行比例)和平均车速等分流特征出发,对单条路段的功能匹配度进行了多层次的定量分析与研究,再依据一定的系统集聚原则,建立了由所有路段的功能匹配度指标计算整个路网功能匹配度的分析模型。在此基础上,给出了功能匹配度分析模型所需要的道路分流特征的提取思路,并以距离分布为例进行了算例分析。
This paper proposes the concept of functional matching degree based on the coincide degree between the actual function and the planning function of road links. According to the separated-stream characteristics of modal split, distance distribution (short, medium, and long-distance travel ratio) and the average speed, the hierarchy quantitative analysis and research of the functional matching degree of links is given in this paper. And on the principle of system aggregate, the computing model of the total network’s functional matching degree is derived from the functional matching degrees of all links. On this basis, this paper presents the ideas for extracting the necessary separating stream characteristics of functional matching analysis. Finally, the computing method of functional matching degree in distance distribution is analyzed as a case study.
