Abstract
The road traffic crash statistics of Addis Ababa shows pedestrian injuries have the highest share
among all road users.This research aims to investigate current pedestrian safety problems in
Addis Ababa and tries to identify factors influencing it.The study area, Addis Ababa has ten sub
cities where Kirkos sub city ranks first with the highest total road traffic crashes.This sub city is
selected as a study site and pedestrian-vehicle crash data for three consecutive years were
collected. These data were analyzed using odd ratio analysis and logistic regression analysis.
Moreover, sample pedestrians and drivers were selected randomly and filled out questionnaire
with list of hundred factors related to pedestrian safety in four categories: pedestrian related,
driver related, vehicle related and road and environment related; which was analyzed by Likert
scale rating and reduced it to top twenty ranked factors.Then these twenty factors; five from
each categories were taken and pair wise comparison by senior experts was employed by
Analytical Hierarchial Process (AHP) technique. Analyzing these resulted in a rank for each
factor with their global weight.The top three are related to driver behavior: alcohol use by drivers
(11.55%), driver rush and negligence (6.084%) and improper or erratic lane changing
(6.048%).The twenty factors were then grouped to the four categories with their local ranking. In
the odd ratio analysis, four hypothesis were tested and only one hypothesis is accepted
indicating drivers with experiences of more than 10 years are most responsible to pedestrian
serious injury. From the logit model driver-vehicle relationship, junction type, pedestrian age and
pedestrian sex are positively associated with pedestrian injuries.Thus in order to take
appropriate measures towards pedestrian safety: pedestrian related factors, driver related
factors, vehicle related factors and road and environment related factors need to be considered
and appropriate measure has to be considered in a systematic way. Rather than a scattered
spots approach by a piecemeal basis; a perspective towards looking the urban network of road
infrastructure, pedestrian facilities and the urban land use is considered in this research. This
research concludes a strategic way has to be followed towards promoting road safety and
pedestrian safety in Addis Ababa that would be an area-wide and multi-disciplinary approach,
that is, urban safety management.
