摘要
针对目前我国对指路标志信息内容组成及协调设置尚无明确规定的现状,对已有的指路标志分析方法及指标作汇总和扩展补充,提出了道路交叉口指路标志定量分析的2个方法:路段分析法与区域分析法,并给出了指路标志设置率与指示范围、道路间相互指示关系等一系列用于上述分析方法的定量分析指标。接着以广州市海珠中心区为例,基于对该区域内主干道指路标志现状的数据采集与调查研究,选取了典型的主干道及交通区域作实例分析。
Aiming at the situation that no clear definitions of the contents of guide signs and the layout of corresponding coordinate equipment have been made in China currently, two methods are proposed to carry out the quantitative analysis about the guide signs at intersection,which are the collection and expansion of the existing analysis method and indexes of road guide signs. The two methods are segment analysis and regional analysis. A series of quantitative analysis indexes which are applied to the method mentioned above are proposed, including the rate of setting guide signs, the range of guide and the guiding relationship between paths. And then a case study is carried out in Haizhu Center District of Guangzhou. Based on the investigation and data collection of the actuality of guide signs at main trunk roads in this region, typical trunk roads and traffic regions are selected to carry out this case study.
