At present, in road traffic examinations (RTE) carried out in the Russian Federation, there are no modern comprehensive studies, scientific and practical solutions and methods which would be dedicated to assessing the risk of obtaining injuries of varying severity by road traffic participants. In contrast to injury assessment in the development of passive safety measures, injury indices in practice are not used in RTE, which leads to a lack of categorical conclusions in a number of expert tasks. The purpose of this study is to define a methodological approach to the solution of specialized tasks of road traffic accident examination and expert prevention of road traffic accidents in general related to the assessment of the risk of pedestrian injury in a road traffic accident. The article presents the analysis results of road traffic accident examinations. The methodology for evaluating the risk of pedestrian injuries in primary and secondary injuries (when being hit by the vehicle and when falling on the roadway) is outlined. The ways of this methodology`s further use in the practice of road traffic accident examinations, as well as in the development of measures within the expert prevention of traffic accidents, are shown.
