Abstract
Globally, road traffic accidents are leading causes of death among young people in general, and the main cause of death among those aged 15–29 years, in particular. In Ethiopia, the average number of road traffic injuries has been increasing from year to year, where Oromia regional State is the major contributor of the total fatalities occurred. The aim of this study is to identify the major factors determining the number of human death by road traffic accident in Oromia Regional State of Ethiopia using an appropriate count regression model based on data obtained from the Oromia Police Commission Bureau that have been recorded on daily basis during July 8, 2016 - July 7, 2017. The descriptive result showed that 2,712 out of 3,900 of the accidents were not fatal accidents. All formal statistical tests indicated that the data are overdispersed and that there are excess zeros. Among families of count models, the hurdle Poisson (HP) model was found to be the most appropriate to the dataset. The results of hurdle Poisson regression model showed that age of driver, experience of driver, type of vehicle, vehicle service, road condition, time of accident, location of accident, environment of accident, type of accident and accident cause were significant factors influencing the number of human death per accident in Oromia regional state of Ethiopia.
