Abstract
Ethiopia is a country with a very large number of traffic accidents and fatality rate,
and the share of the city of Addis Ababa is quite big (about 60%). Pedestrians and the
disabled, children and the aged in particular, are the major victims of these accidents.
The aim of this thesis is to analyze fatal traffic accidents in Addis Ababa and identify
factors that contribute to the occurrence of road traffic accidents leading to fatalities.
This study applies four count models namely Poisson, negative binomial (NB), zeroinflated
Poisson (ZIP), and zero-inflated negative binomial (ZINB) models to
establish the relationship between the number of fatalities per traffic accident and
human, environmental, road and vehicle related factors. Data regarding to number of
fatalities per traffic accident were obtained from AATCID for a one year period from
April 2012-March 2013. Drivers in the age group 18-30 years, the drivers having less
than 5 years of experience and those who are employed were highly associated with
the number of fatalities per accident. Among vehicle related factors automobile, taximinibuses
and vehicles less than five years of service were highly associated with the
number of fatalities.
