Also Ethiopia share this traffic crash death. Modjo to Hawassa road is in Oromia Regional State one of Ethiopia’s high fatal and other traffic crash injury severity roads. The road inter connects Addis Ababa city with some parts of south eastern Ethiopia. The main objective of this thesis is to analyze effects of drivers’, vehicle and road characteristics on injury severity of crash victims and assessing the remedial actions. The five year traffic crash data was used. Multinomial logistic regression model is used to analyze the dependent and independent variables. Explanatory variables such as drivers not obey traffic rule and regulation, drivers their ages are between 18-30 years, drivers education levels are high school level, vehicle types are small truck such as Isuzu and FSR and medium trucks like Sino trucks, when roadway conditions are damaged, vehicle defects, light conditions are dark night are identified as factors increasing fatal, severe, and slight injury severity of pedestrians, passengers, drivers and cyclists. Explanatory variable factors such as higher drivers driving experience in years, newer vehicles, when drivers’ age increases, when drivers’ education level above high school, when vehicle types are trucks and trailers and light conditions are day light decreased fatal, severe and slight injury severity traffic crash. Drivers of small trucks such as fright Isuzu, FSR and medium trucks like Sino Truck, which do not obey the roadway rule and regulation most of the time engaged in pedestrians’ fatal crashes and crashes with cars results in fatal and severe injury severity of traffic crashes. The unknown drivers and vehicle types (drivers hit and runs) are drivers which hit and run post crashes and they crashes with pedestrians, animal cart drivers and cyclists at the rural area, night, early morning and evening time. The remedial actions are giving the training on road rule, regulations and guidelines for the drivers, regularly doing road maintenance and rehabilitations for damaged roadway, traffic signs, signals, pedestrians crossing painting color. The findings of the study and evaluations of remedial actions significance are compared with the results of developed country scholar’s researches. The details evaluations of the significance of remedial actions, comparing the results model with mixed logit model, ordered logistic models and factoring independent variable are the research gap of this study and it is recommended as future study.en-USRoad Traffic Crash InjuryRemedial actionsModjo-Hawassa RoadThesis
