结合交通组织管理的需求布设指路标志是均衡路网流量、提高路网整体通行能力的重要途径。建立了指路标志指引信息的数字化表述模型;根据出行者运用指路标志指引的寻路习惯,定义了用于路径搜索的有效信息集;给出了基于既定规划路径的指路标志指引信息分析模型,并构建了评价指标,该指标可定量评价指路标志的布设与规划路径指引的相符程度。最后,以广州珠江新城为例,选择了一条规划路径,对规划路径上的指路标志进行了指引效果分析。实例表明,本算法是有效、可行的。
Combining with the needs of traffic organization and management, laying road signs is an important way to balance the traffic on the road network and improve the overall capacity of the road network. A digital representation model of guiding information of guiding signs is established. According to the way-seeking habits guided by the guiding signs by travelers, an effective information set for route searching is defined. An indexing guideline of guiding signs based on an established planning path is given Model, and builds the evaluation index, which can quantitatively evaluate the consistency between the layout of the guide signs and the guidance of the planning path. Finally, taking Guangzhou Pearl River New City as an example, this paper chooses a planning path and gives guidance and analysis on the guiding signs on the planning path. The example shows that this algorithm is effective and feasible.
