| 摘 要： | 道路系统中诸因素共同作用决定了系统的交通安全发展态势。如何在众多因素中寻找主要致因,是进行道路安全改善时所必须面对的问题。考虑到数据获取贫信息的特点,采用灰色关联分析,不但可以提高现有数据的利用率,而且弥补常用数理统计方法作系统分析所导致的缺憾。实例分析表明:采用此方法所得到的主要道路影响因素和交通安全之间的关联度大小与实地踏查结果相吻合,结果说明灰色关联度可以简单而高效地进行系统因素辨析。

| Abstract: | The common effect of various factors in road system determines development state of the traffic safety.It is the problem how to search main factors in various factors,which must be faced in carrying out the safety improvement of road.Considering the characteristics of poor information during obtaining the data,the grey incidence analysis is adopted,which not only can improve the utilization efficiency of the existing data,but also can remedy the limitation of that carrying out systems analysis by mathematic... |
