基于云物元综合评价理论下的高速公路诱导信息有效性研究

Research on Highway Induction Information Validity Based on Cloud Matter-Element Comprehensive Evaluation Theory

根据高速公路诱导信息的相关特性,从动态信息、静态信息、动态反馈信息三个维度建立了高速公路诱导信息有效性评价指标体系;将云理论与物元方法相结合,构建了云物元综合评价模型,实现了只能用自然语言值描述的定性概念的物元表示;最后通过实例运算,对该模型的合理性和可靠性进行了验证.评价结果表明:该模型在高速公路诱导信息有效性综合评价中具有较好的应用效果.

According to the characteristics of highway induction information,the validity evaluation system is established by the dynamic information,the static information and dynamic feedback in-formation.Combining the cloud theory with matter-element method,a comprehensive evaluation cloud matter-element model is built and the matter-element representation of qualitative concept which can be only described by the natural language value is achieved.Finally,the rationality and reliability of the model are verified by taking an example.The results show that the model has a better effect in evaluating validity of highway induction information.
