摘　　要：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。The layout of road guide signs considering with the demand of traffic organization and management plays an important role in road network flow equilibrium, which can improve traffic capacity of road network. The digital model for guiding information of guide sign was proposed. The effective information set for the path-searching process in guide sign system was defined according to the travelers＇ path-finding habits of using guide signs. The analysis model of guiding information of guide sign based on the defined planned route was given. The evaluation index which can be used to quantitatively evaluate the match level between the layout of guide signs and guideline of planned route was constructed then. As an example, a planned route in Guangzhou Zhujiang New Town was chosen, and the guidance effect of the road guide signs in the planned route was analyzed by the present model. It shows that the model is effective and feasible.
