摘　　要：目前仅参考行政等级的指路标志指引信息分层原则不能客观地反映县级行政区的交通需求。为了优化县级行政区指路标志指引信息设置策略,增强路网功能,提出了一种基于主客观赋权-TOPSIS法的县域指引信息重要度评估方法。首先,结合中国县级行政区特点细化评价颗粒度,构建了涵盖人口、面积、经济、旅游景区数量、路网规模等11项指标的评价体系;其次,采用量表分析法对主观指引信息重要度进行统计学分析得到主观权重;然后,采用主成分分析法基于指标内部客观特性进行赋权,将累计解释方差率达到85%的主成分按照对应特征值加权求得重要度客观得分,并采用TOPSIS法对主客观得分进行综合评价,得到每个样本在主客观2项指标下的相对贴近度;最后,根据县级行政区相对贴近度在本省对应的z分数得到高指引信息重要度的县级行政区清单,作为指引信息选取的决策依据。以2组高速枢纽立交为例,根据主客观赋权-TOPSIS法的评估结果,提出了对应转换节点处县级行政区的指路标志指引信息选取方案,并结合实地调研结果验证了本研究提出的评估方法的合理性。结果表明:所提出的方法优化了指路标志指引信息设置策略,可为指路标志版面信息选取提供参考。In county-level administrative regions of China,the hierarchical principle of signage guidance based solely on administrative rank sometimes fails to objectively reflect the transportation needs.To optimize the strategy for setting signage guidance in county-level administrative regions,and enhance the road network functionality,this study proposed the assessment method for guidance information importance based on subjective and objective empowerment-TOPSIS approach.First,tailored to the characteristics of county-level administrative regions in China,the evaluation system covering 11 indicators(i.e.,population,area,economy,number of tourist attractions,road network size,etc.)was constructed.Second,the subjective guidance information importance was statistically analyzed by using the Likert scale method to obtain the subjective importance scores.Third,the principal component analysis was employed to objectively weight the indicators based on their internal characteristics.The principal components,which achieved the cumulative explained variance of 85%,were weighted according to the corresponding eigenvalues to obtain objective importance scores.Subsequently,the TOPSIS approach was used to comprehensively evaluate the subjective and objective scores,obtaining the relative closeness degree of each sample with both subjective and objective criteria.Finally,based on the relative closeness degrees of county-level administrative regions compared with corresponding z-scores within the province,the list of highly important county-level administrative regions was generated,serving as the basis for decision-making in signage guidance selection.Taking two expressway interchanges for examples,based on the assessment result with subjective and objective empowermentTOPSIS approach,the signage guidance information selection schemes were proposed corresponding to the transformation nodes of county-level administrative regions.The rationale of proposed assessment method was verified through the field surveys.The result indicates t
