    (2016-10) ABAH, Onyikwu Victoria
    This study analyzed the spatio-temporal pattern of road traffic accident black spots in Kaduna. Among the objectives were to determine the spatial pattern of road traffic accident black spot, examine its temporal variation, characterize road traffic accidents as well as assess the road way nature at the black spots. Road traffic accident data were collected from Federal Road Safety Commission (FRSC) from year 2006-2014. Also field survey was carried out through which the geographic coordinates of road traffic accident locations were taken as well as on the spot field observation. Data were analyzed using the Kernel Density Estimation method in ArcGIS 10.1 environment to determine the road accidents black spots and frequency distribution tables and charts in Statistical Package for Social Science (SPSS) and Microsoft Excel.The findings show that the black spots along Zaria-Kano road includes, Yan Karfe, Dogarawa, Zabi and Anur Mosque while Polo Field, MTD, Palladan and Zango account for those along Zaria-Sokoto road of which about 66% of the total road traffic accidents took place in the black spots identified along Zaria-Kano road with Dogarawa (23.8%) recording the highest while Palladan (11.3%) recorded the highest among those along Zaria-Sokoto road. The temporal variation reveals that year 2012-2014 has the highest number of road traffic accidents black spots of 10 locations accounting for about 63% of the total number of accidents recorded, while the least was between years 2009-2011 with 5 black spots representing only 23% of the total number of accidents. It was also observed that 75% and 60% of the road traffic accident black spots identified between years 2006-2008 and 2012-2014 respectively were along the Zaria-Kano road as against 25% and 40% along Zaria-Sokoto road during the same period. The study reveals that about 85% of the death cases as a result of road traffic accidents at the black spots were recorded along Zaria-Kano road with Anur Mosque (33%) having the highest, while only 3% represents the least recorded xiii at MTD along Zaria-Sokoto road whereas Dogarawa has the highest number of injured persons as a result of road traffic accidents.Regarding the road designs, most black spot locations were characterized by sharp bends, U-turn and intersections. Also, other road conditions like presence of potholes, eroded road shoulder and stationary vehicles were found at the various black spot locations. The study recommended among others, emergency healthcare services to be provided at the various black spots locations on the highways, road safety strategies like compulsory use of seat belts, legislation on speed limits should be strictly enforced by the FRSC, construction of road traffic signs especially at the black spot locations and education of the drivers on meaning of such signs.
