Abstract: When calculating the highway nodes’ importance, ordinarily the indexes and their weights of the nodes are subjectively decided. This paper brings forward a new method to select the indexes of the nodes and get their weights objectively based on Degree of Gray Incidence. This method can avoid arbitrariness

Key words: highway planning, node important degree, selecting index, objective weight

摘要： 在计算公路网规划节点重要度时,节点指标选取及其权重的大小通常采用主观方法确定,笔者提出了以灰色 关联度为基础的指标选取及其权重的客观计算新方法,避免了主观的任意性.
