摘　　要：根据路段相对重要性的度量依据,首先分析了路段相对重要性直接度量法的不可行性,然后以路段可靠性重要度为工具,通过比较路段的可靠性重要度,从而间接确定了路段相对重要性,并给出了算例。另外,以边际可靠性重要度为工具,提出了路段相对重要性的另一种间接度量方法,并给出了算例。最后,简单说明了路段相对重要性在路网设计中的应用。The unfeasibility to directly compute the link relative importance has been analyzed according to its evaluation base. And then an indirect method to evaluate the link relative importance has been established by employing the reliability importance of link. Therafter, an example is gave to prove the validation of the method. In addition another indirect method to compute the link relative importance is studied by using marginal reliability importance. Similarly an example is demonstrated to illustrate the validation of the method. Finally the link relative importance is combined to the road network design.
