| 摘 要： | 为反映山区农村公路危险性的实际情况,筛选影响交通安全的相关因素,建立山区农村公路路侧危险等级评价体系。基于集对分析(SPA)方法,引入能够体现系统确定性与不确定性的同异反联系度(IDC)的计算公式,并建立山区农村公路路侧危险等级评价的集对分析模型(SPAM)。模型从3个层次阐明评价过程中SPA的具体意义,并将多指标表示成一个能从总体上衡量道路危险性的n元联系数。用层次分析法(AHP)确定指标权重,从主观和客观两方面定量计算山区农村公路危险程度。承德某山区农村公路的模型应用实例表明:SPAM模型充分利用研究问题所包含的不确定性信息,将辩证认识与定量描述有机结合起来,是山区农村公路复杂系统综合评价的一种新方法。

| Abstract: | Considering the related factors effecting of traffic safety,a road-side risk rating evaluation system is established to reflect the risk reality of rural roads.Based on SPA theory,the identity-discrepancy-contrary(IDC) connection degree formula which can embody certainties and uncertainties of the assessment system is introduced and Set Pair Analysis Model(SPAM) is established for road-side risk rating system assessment.The meanings of SPA applied to road risk rating system assessment at three levels are fu... |
