Abstract: Traffic accident is increased from time to time in alarming rate and it is a serious problem throughout the globe, particularly, in developing countries like Ethiopia. In this study our aim was to identify the major factors that affect the occurrence of traffic accidents at Bahir Dar city, North Western Ethiopia. The drivers were selected using simple random sampling methods and descriptive statistics, Chi-square and Binary logistic regression methods have been used for data analysis.The Hosmer and Lemeshow test showed that the model fits the data very well. And from the result we have seen that drivers giving priority stated by the law, pedestrian’s manner while crossing the road, drivers usage of seat belt have statistically significant impact for the occurrence of traffic accidents in the city. Pedestrian’s manner while crossing the road is one of the significant variable for the occurrence of road traffic accidents in Bahir Dar city. Therefore, the traffic polices or concerned body should give trainings for pedestrians about traffic accidents. To minimize the road traffic accidents, the government should set the rules to use the seat belt so that the drivers should apply it.

Abstract: There are several ways in which regression model can be validated. One of the ways is a collection of new data to check model predictions (Snee, 1977). In Nyakyi et al. (2014) a multiple regression model was formulated, analyzed, and discussed to assess motorcycle accidents in Tanzania. The model included several factors which are wrong overtaking, legal status of not owning license, rough road, high speed, mechanical defect, personal status, experience of a driver, and tarmac road. All these factors were considered to be the causes of motorcycle accidents in Tanzania, specifically in Arusha and Kilimanjaro regions. This paper presents the analysis and discussion of the accidents problem using new data collected through questionnaire; the study's results are then compared with the results, predicted by the multiple regression models, for validation. Questionnaires were designed to access the extent to which identified factors cause motorcycle accidents, and the data is obtained from motorcycle stake holders who in this study are considered to have reliable information about motorcycle accidents in Tanzania. The results of the validation indicate that there is a good correlation between the data obtained from the questionnaire and the data produced by the regression model.
