| dc.description.abstract | The main aim of this research study is to analyze and evaluate the cause of road traffic accident in Addis Ababa Bole Sub City and to recommend safety measures at identified black spots to create a safer transport system in the sub city. Bole sub city, being the largest sub city in the city, enjoys the city’s major road compositions as well as local and international gate ways with high standard roads. Unfortunately, it has recorded the worst accident and safety record in the city as well. The study uses GIS based black spot identification schemes that employs five distinct scientific principles namely: accident frequency, accident rate, empirical Bayesian, critical accident and accident prediction models. A total of 31 sections of road and 9 junctions were studied using primary and secondary data. Out of the methods, empirical Bayesian proved superiority so that much of the conclusion was based on this method. Results indicate that road sections 29, 11, and 10 were highly prone to accidents with PI EB values of 57.24, 55.4 and 53.55 respectively. The worst junctions were Emperial roundabout, Bole Michael roundabout and Millennium Hall intersection with PI EB values of 257.46, 222.43 and 121.25 respectively. Values of PI EB indicate that these sections need urgent attention to diagnose, prioritize, evaluate and give low cost and effective solution to reduce road traffic accident and increase safety performance. Possible solutions are using traffic signs, user awareness campaigns, policy revisions, and permanent geometry and pavement modifications | en_US |
