【摘要】 道路交通安全系统的内部结构极为复杂,影响因素众多,各因素权重信息不能完全被确定.提出了对于属性值以模糊区间数这种不确定形式给出,着重以“人”、“车”、“路”中的“路”对交通安全的影响进行模糊区间综合评价,建立了评价指标体系,用层次分析法确定了判断矩阵,并利用模糊区间综合评判模型得到了一种交通安全性评价方法.更多还原

【Abstract】 Because a traffic system is very complex,it’s quite difficalt to evaluate the traffic safety of a highway.In this paper,an attribute value with a fuzzy interval number was given in order to investigate the effects of "human being","automobile"and"road"on the traffic security of a high way,an evaluation system is set up,and a judging matrix is formed by AHP.A new method for evaluating the traffic satety of a highway is put forward using a judgment model based on a fuzzy model with a fuzzy interval number.更多还原
