摘要
针对当前国内外各城市的指路标志标识系统以经验作为布设主要依据,具有主观性和不合理性的现状,提出了一种在提取系统经验性特征的基础上,结合客观性特征对道路指示信息进行修正的方法,该方法通过定义指路标志项系数,作为指路标志标识系统的特征表述,并结合路网拓扑进行修正,实例证明修正结果有效降低了系统的不合理性,提高了路网拓扑反映的客观性,可为实践中指路标志标识系统的布设提供参考。
The Guide sign system, which mostly has its establishment focused on personal experiences, has the drawbacks of excessive subjectivity and rationality absence. This paper bringed forward a method of amendment that combined experience factors with objective factors. It defined the guide sign item coefficient which represents the characteristic of the guide sign system, then proceeded the amendment through topology relation between roads. Application showed that the result of amendment, which can be used as reference of guide sign planning, effectively debased the illogicalities of the system, and enhanced the rationalities reflected by topology.
