This project's main purpose is to provide reliable predictors of road accidents for highway development models used in the planning stage of new or upgraded roads. The project has aimed to concentrate on those road features which have been identified by other researchers as having a significant impact on road safety, especially in developing countries, and those features over which the engineer has some control. Much work has been done examining the impact of road characteristics on safety in the Northern countries and in Australasia, but there is a lack of substantive research in low-Income (LI) countries where road conditions and the pattern and types of road users can be very different compared to High-Income (HI) countries.
This study has aimed to assess the suitability of several methods which have been developed in HI countries for use in the HDM-4 model in order that the costs associated with road accidents can be taken into account in economic decisions. The methods will be evaluated using data specifically collected for this purpose from two developing countries (Tanzania and India).
