The purpose of this book is to show how to develop a mathematical model for road traffic accident costs in developing countries. Life insurance and Log - Logistic regression analysis were used to develop the model. It was tested and found out to be statistically the same as the human capital approach of costing road traffic accident even at an extreme risk of 42.5%. The model could be used by road safety stakeholders for decision making to invest in road safety of developing countries. Then, the modelling techniques could be used not only in road accident costs but also in any science and...
