Increasing road traffic accidents are a major threat to life in many parts of the world. To ensure safe, effective and sustainable transportation system at Khulna Metropolitan city which is the third largest metropolitan city of Bangladesh, it is indispensable to understand the current situation of road traffic accident of this area. A very few research works with detailed analysis of road traffic accident have been carried out in Khulna Metropolitan city for a full understanding of accident problem. Because of the alarming increase of the road traffic accident at Khulna metropolitan city, it is important to develop road accident models considering the basic factors of those causing accident in this area. In this study, all the reported accidents by Khulna Metropolitan Police during the period of 2000 to 2010 are analyzed. The aim of the present study is to develop models by analyzing these road accident data for five police stations of Khulna metropolitan city. The data for the period of 11 years are analyzed to understand the nature and extent of the causes of accidents using the concept of Smeed’s formula and Andreassen’s equations. As the variation between actual number of accidents and the accidents obtained from these formulas are quite high, a new inverse model is proposed. These accident prediction models can be used as effective tools in road safety analysis for Khulna Metropolitan City.

Key words: Khulna Metropolitan city, accident prediction models, Andreassen’s equations, Smeed’s formula, Inverse model.
