This datasheet provides information on land transport accident statistics for use in Quantitative Risk Assessment (QRA). The datasheet includes guidelines for the use of the recommended data and a review of the sources of the data. Most of the data concern motor vehicles and rail transport, although some data for cyclists are also presented. Data excludes pedestrians; if this is needed local data will need to be examined. The data in this sheet are intended for two main uses: • Assessing the risk of transporting personnel; data relating to the frequency of fatalities and serious injuries to road and rail users are presented. • Assessing the risks of transporting Dangerous Goods (DG); data on the frequency of releases of hazardous materials from rail and road tankers are presented.
