| 摘 要： | 根据服务水平评价不需要精确值的特点,本文运用定性推理,结合定量空间、定性关系等定性定量方法,提出了研究交叉口行人服务水平评价指标-行人信号延误的新方法.文章推导出了信号延误的定性推理结构,确定了变量的定量空间,进而通过推理形式表征了变量间的定性关系.结果表明,定性推理得到的信号延误定性值可以较好地符合服务水平指标值的区...

| Abstract: | According to the unnecessary of an accurate value for evaluating of service level,a model to study pedestrian service level evaluation index named pedestrian signal delay at intersections was presented combined with the qualitative space,and qualitative relationship.A qualitative reasoning structure of the signal delay was deduced and the qualitative space of the variable was determined.Furthermore,a qualitative relation among the variables was expressed.The results showed that qualitative value of the sign... |
