Researches on the correlation between the projection distance of bycicle riders and the speed of motor vehicles at the moment of impact

Abstract

Recently, the presence of two-wheeled vehicles is increasingly felt in urban agglomerations. For this reason, the incidence of accidents involving two-wheeled vehicles has increased substantially, on the one hand, due to the lack of infrastructure to ensure the maximum safety of cyclists and, on the other hand, due to the lack of discipline of cyclists, extra-urban traffic. A very important element in the reconstruction of traffic accidents involving cyclists is the speed of the vehicle at the moment of impact. In the present paper there are some relationships that can be used successfully in calculating vehicle speed at the moment of impact by bicycle.
