The dissertation included three scientific studies. Data from the respective offices on crashes, traffic and the geometric design of roads were obtained. To examine the spatial patterns of Crashes and identify crash hotspots in Ethiopia, the spatial autocorrelation of crashes and Getis-Ord-Gi* statistics in ArcGIS were used. Moreover, the Crash Prediction Model of the Highway Safety Manual and Interactive Highway Safety Design Model has been exploited to evaluate the safety performance of rural roads and quantify the safety effects of road design improvements made to existing roads |
