摘　　要：为实现对指路标志指引信息连贯性的分析评价,首先介绍了基于路网拓扑结构的指路标志指引信息表述模型,该模型可支持对指路标志布设现状的分析评价。进一步分析了出行者在指路标志诱导系统中的寻路过程,基于此对指引信息的连贯性进行了定义。以上述理论为基础,建立了用于搜寻指路标志指引路径并对其连贯性进行分析的算法模型,同时构建了指引信息连贯性的评价指标。最后,以广州珠江新城为例,对其指路标志诱导系统指引信息的连贯性进行了分析评价。实例表明:本算法模型是有效可行的。In order to analyze and evaluate the guiding consistency of guide sign system, the representation model for guiding information based on the topology of road network was introduced at first, which can support the analysis and evaluation for guide sign deployment. The definition of guiding consistency was given according to the travelers＇ path-finding process in guide sign system. Then, the analysis algorithm model for path-finding and the guiding consistency analysis was constructed based on the abovementioned theory, meanwhile the evaluation index of the guiding consistency was proposed. Finally, taking Guangzhou Zhujiang new town for example, the abovementioned model was applied to evaluate the guiding consistency of its guide sign system. The example shows that the model is feasible and effective.
