Road traffic accidents have been recognized as one of those adverse elements which contribute to thernsuffocation of economic growth in the developing countries, due to the heavy loss related to them, hencerncausing social and economic concern. Traffic safety is an important key and plays an integral role inrnsustainable transportation development areas. Now days, the main negative impact of road transportationrnsystems are loss of property, injuries and deaths in road accidents. rnThe objective of this study is to Assess GIS based Road Traffic Accidents black spot Sites related issuesrnof Kirkos sub-city in terms of frequency, time and space from 2014 to 2018. The pivotal data necessary forrnthe study was collected from the daily Road Traffic Accident records format of the Kirkos Sub city. Besides,rnpoint based traffic accident sites were collected using GPS data-logger devices, it was converted in tornshape file using ArcGIS 10.2 software by uploading via DNRGPS 6.0.0.8 application software thenrnâ€žJoins and relatesâ€Ÿ function. Thesis applied the combination of geo-information technology and spatialstatisticalrnrnanalysis to bring-out the influence of spatial factors in their formation. The results werernpresented in the form of line graphs, crosstabs, pie charts, figures and black spots maps. rn A traffic accident has multi-facet characteristics associated with it. For proper traffic accident black spotsrnidentification use of GIS technique has become an inevitable tool. The result of the study revealed thatrnabout 1154 people were affected by Road Traffic Accident casualties. In this connection, the road crashesrncoasted 537,563,785 ETB from 2014/15 to 2017/18. Besides, 54 Road Traffic Accident Black Spots, toprn10 as well as 5 consistent Road Traffic Accident Black Spots have been identified and mapped for thernsub city. This Study examined the relations between traffic accidents and city characteristics, such asrntrend, road factors, and spatial factors. In general, the location of traffic accidents is described as anrnaddress with text, so they are difficult to display on the map. These are concern with how to utilize thernGIS to work-out on spatial analyst to record the traffic accidents, to map and identify road traffic accident rnblack spots. Remedial measures and provisions for traffic safety are suggested for reducing the risk of accidentsrnin black spots.
