Abstract
Nowadays, the main negative impact of road transportation systems is the loss of property,
injuries, and deaths in road traffic accidents. Ethiopia hosted an average of 13 fatalities and 37
people for disability per day, from this Addis Ababa shares 10 % of fatality and 26 % of
disability. In Addis Ababa city 70 percent of pedestrian deaths occurred when walking for
crossing a road. There is a strong relation between road traffic accidents and pedestrian
accumulators, especially, bus stops. The primary objective of this study was to assess road traffic
accidents to identify black spots and hazardous bus stops in Yeka Sub-city administration (which
is the second leading sub-city by road traffic accident after 2017). The data collection techniques
of this study were questionnaires, interviews, and field observation. The primary data collected
from questionnaires distributed to 60 city bus drivers (by using a simple random sampling
technique) and 5 key informants. In addition to this Global Positing System (GPS) were used to
collect x,y coordinates of bus stops and uncollected fatal accidents in 2019; whereas the
secondary data were collected from Yeka sub-city police commission (non-spatial data) and
Addis Ababa transport program management office (the spatial data). The applications of GIS
such as interpolation and kernel density functions, buffering were used to produce a continuous
surface, magnitude per unit area proximity respectively. The analysis was done using Arc GIS
10.3 and 10.5 software and Microsoft excel. 97% of all traffic accidents caused by male drivers,
and Mondays, Thursdays, and Fridays which were more frequent traffic accident registered
days. Inapt use of steering and driving closely were the primary causes of a road traffic accident
and 52 percent of fatal accidents were caused by failure to give pedestrian priority. Ferencay
Kela, Megenagna, Wesen Grocery, Aboare, Kara Akababi, Yeka Michael, and Gurd Shola were
identified hotspot areas. Kokebe Tsibah, Lamberet Terminal, Ayat-Tafo entrance; CMC St.
Michael, Yeka Sub-city Administration Roundabout, and Ferencay Biret Dildiy were
hazardous/unsafe bus stops. The researcher recommended that special inspection and priority
should be given for those identified black spots sites and hazardous bus stops. Traffic
management agency and other concerned bodies should construct overpasses or bridge, fence,
and relocation activities over those hazardous/unsafe bus stops.
