Road safety determinants in low and middle income countries.

The objective of this article is to summarize and review the literature on the determinants of road traffic injuries and fatalities, to identify the relevant research gaps in particular for low and middle income countries. We also present a cross-country analysis of the determinants of road traffic injuries and fatalities that take into account a wide range of potential environmental, economic and social factors. The present study focused on differences based on the level of development. The goal was to identify relevant commonalities that may assist in the creation of road safety policies common to countries at a similar level of development. The countries were divided according to the level of gross national income per capita, and these income-level groups were the primary units of interest. The results presented here focus on the differences by income level.
