Abstract

In Ethiopia, road crashes are among the leading causes of death and injury. Road crashes cannot be absolutely eradicated. The behavior of derivers plays a role in the occurrence of road traffic accidents. So, it is important to figure out the role of the non-behavioral factors in road crashes. The study considered data from a total of 5,251 road traffic accidents from 2011 to 2014 in Yeka suburb, Addis Ababa, Ethiopia. In order to assess the effects of non-behavioral factors the study used frequency analysis, negative binomial and a logit regression model. Based on most frequency analysis non-behavioral factors which caused road traffic crashes in the suburb was day time and light, straight path, good asphalt and weather, and dry surfaces. In addition to that, roads without median and intersection, populated non business districts also played a vital role. The study shows that road traffic accidents have significant positive relationships with non-behavioral factors like road surface conditions, lighting conditions and maneuvering conditions. As a result; the study suggests that non-behavioral factors have an effect on road traffic accidents.
