Using Factor Analysis to Study the Effecting Factor on Traffic Accidents

Abstract

This paper is concerned with the study of the factors that have significant effects on contracting traffic accidents. Another aim is to know whether the influence of each variable is independent or has a relation to that of other once. The sample of the research included (150) traffic accidents, the sample was collected from (Directorate of Traffic / Garmian ) in the period (2013-2014). Measures of nine variables have been taken. And principal component method was used on the studied variables data to specify the importance of these variables. As well as, Varimax method was used to rotate the axis to get an easier and more specific result. The results have showed that the following variables have clear influences but their importance is different in terms of influencing on traffic accidents. We find that the variables (driving license) and (type of accident) have comes in first rank, while the other factors comes in later rank.
