| 摘 要： | 对灰色理论在交通安全评价领域应用的可行性进行探讨。针对经典白化权函数的弊端，建立基于指数的白化函数，使得评价对象属于不同安全等级的权值差别明显。提出了改进的灰色聚类法的具体步骤。并结合应用实例进行详细阐述。

| Abstract: | The possibility of applying grey theories in traffic safety field was discussecl in this paper. Aiming at the disadvantages of classical whitening function and having set a new whitening function based on exponents, it makes the differences in weight value of objects being evaluated obvious. This paper put forward the approach of the improved grey cluster and completely discusses the model combining real cases of applications. |
