Abstract

Every year, road traffic accidents cause direct and indirect loss in gross national product in every community. The present study aims to provide a methodology to estimate the costs of road accident fatalities in Iran. In this research, using different available methods namely the “Court Award” and the “Lost Product”, the average costs of individual road traffic fatalities have been determined, separately. The annual road fatality rate in the road network has also been estimated using 12 ARIMA(3,0,0)×(1,0,0) model of time series. Combining the each separate estimate of road fatality cost with the number of road traffic fatalities in a single measure, two measures of lost in gross national product due to road fatalities have been estimated. Finally comparing the results with the observed number of fatalities for the next years, the two methods of fatality cost estimation have been compared in terms of validity. In other hand, used method is statistical-economic. Analysis of road accident fatalities by the “Court Award” method shows a descending trend of loss in gross national product followed by an ascending trend, during 2010 to 2012. Application of “Lost Product” method of road fatality cost estimation on the same database however, indicated a totally descending trend. Finally and Comparing the estimates of the two methods inferred that the “Lost Product” is a more promising method in estimating the gross national product loss due to road traffic fatalities, since the lost amount in this method remains proportional to the number of road traffic fatalities.
