Abstract
Road traffic crash is a serious problem in the world and highly prominent in developing
countries. Road traffic crash cannot be totally stop, but using appropriate engineering measures
and road safety management and improvement the traffic crash rate can be decrease. The road
safety improvements are supposed to be implemented to the hotspot location of traffic crashes
where they have the most significance and on the other hand, excessive speeding is also one of
the road safety problems. Thus, this study aimed at investigation of hotspot location and
excessive speeding in Addis Ababa city. To meet the objective of the research the researcher has
given attention to collect traffic crash data and excessive speeding data from Addis Ababa Police
Commission. The hotspot location identification was based on the ArcGIS software using Kernel
Density Estimation and Getis-Ord Gi* tools in the software. Hence, the results of a study
regarding excessive speeding showed the existence of huge disparity among drivers’
demography by their gender, age & driving experience levels, and vehicle types engaged in
speeding and variation of the extent of speeding above the posted speed limit among posted
speed limit. Comparing gender, male drivers were the most frequently engaged in excessive
speeding than female drivers in the city. Moreover, the results confirmed that young drivers
under the age categories from 25 to 40 regardless of their gender and those drivers less than 5
years driving experience are highly involved in excessive speeding. Based on vehicle type’s
automobile, pickup, and mini-bus are the first three mostly involved in excessive speeding. More
than 69% of speeders in city were driving by more than 10kmph above speed limit. The extent of
speeding of those divers engaged in speed violation decreases as the posted speed limit increases.
Furtherly, this study confirmed that the significant growth of traffic crashes in the city annually.
The major causes of traffic crashes revealed in this study are following too closely (25.6%),
failure to give-way for other vehicle (21.3%) & pedestrians (10.1%), improper overtaking (8.7%)
and improper parking and moving from (8.2%), over speeding (7.6%) etc. The other finding of
this study is the investigation of a hotspot location. The hotspot location of fatal traffic crashes
identified is Megenagna intersection, Sebetegna, Asra Simint to Atena Tera and Zenebework
along the ring road, and Ayer Tena along Jimma road where high vehicular and pedestrian
movement and excessive speeding were expected. Finally, the hotspot location of injury traffic
crashes identified in the study was Mexico to Leghar to Stadium,to Urael along LRT route, Auto bis Tera to Atekilt Tera route, Ayer Tena to Miachel Adebabai to German Adebabai to Haile
Garment route.
