摘要
针对"环形+放射"这一特定形态的路网,研究了其指路标志的布设模型及其指引评价方法。首先,分析了"环形+放射"路网的结构和功能特色,根据环形道路承担过境及区间交通、放射性道路承担内外出行的功能,分别构建了环形道路和放射性道路的指路标志布设模型。然后,结合"环形+放射"路网的指引需求,提出了环形和放射性道路的整体指引可达性评价方法。最后,以广州大学城为例进行了应用试验,并将现有方案和设计方案进行了对比分析。结果表明,该模型的整体指引可达率明显高于指路标志现状,更具可行性。
For the road network of“ring+radiation”,the layout model and evaluation method of its guiding sign are studied.Firstly structure and functional features of ring radial road network are analyzed.And based on the features which ring roads are designed for transiting transportation and transportation between areas while radial roads are designed for transportation between inside and outside,this paper proposes the deploying models for ring roads and radial roads respectively.Then combined with guiding demand of the Ring radial road network,this paper provides an evaluating method of guiding accessibility for ring roads and radial roads.Finally,the model is applied in Guangzhou Higher Education Mega Center.After comparison and analysis to the current deployment,the guiding accessibility of the experimental results is obviously higher than that in the current deployment.That is proved that the model is effective and feasible.
