dc.description.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.
