Scientific Essay from the year 2017 in the subject Transportation Science & Technology, Ethiopian Civil Service University, language: English, abstract: This paper assesses the trends, causes, and costs of road traffic accidents in Ethiopia. Despite efforts made by various stakeholders to reduce the massacre on Ethiopian roads, road traffic accidents have been a serious health development issue in the country. The essay used data on road traffic accidents in Ethiopia for the period 2006 -2015. Data were obtained from Federal Police Commission and Federal Road Authority and analyzed using descriptive statistics. The study found that at national level, on average road traffic injuries are increasing from year to year where Oromia regional state is the major contributor of total fatalities occurred in the past decade. On the other hand, Addis Ababa city administration is found as a major contributor of serious and slight injuries as well as property damages. The study showed that alike any developing countries, pedestrians and passengers are found to be the most vulnerable and hardest hit segment of road users. The finding also showed that male road users who are in their productive age group are disproportionately affected by road traffic injuries. Human errors (mainly drivers' behavior and actions) are found as the major cause of road traffic accident in Ethiopia. So as to reduce fatalities and injuries on Ethiopian roads, the essay recommends that road safety policy and law enforcement; capacity building, education, and awareness creation; and cooperation and integration between and/or among all transport stakeholders should be the focus of Ethiopian government.
