摘　　要：根据公路线形空间几何特性,采用高速公路空间曲率指标作为客观指标,根据驾驶员NASA-TLX评价量表计算的主观指标,并针对道路交通安全概念的模糊性,运用聚类分析,构建了高速公路主客观安全性的方法与模型。实例表明,符合客观实际,为今后进行高速公路线形安全性评价提供参考。According to the road alignment spacial geometric properties, this paper firstly adopts spatial curva ture of expressways as objective index, and integrates the NASATLX scale of drivers as subjective index. Then the model of the subjective and objective safety is constructed according to the fuzziness of road safety and with the application of clustering method. The case study shows that the model corresponds with the reality, which can be applied to the expressway linear evaluation for future reference.
