This systemic approach recommends taking joint action on the various pillars of road safety (management, vehicles, infrastructure, users, post-accident) and avoiding siloed approaches. Because humans have physiological limitations in the event of a collision and limited cognitive abilities (propensity to make mistakes), road safety interventions must both prevent accidents from occurring and reduce their consequences for victims. With this in mind, efforts are undertaken to reduce the implications of excessive and inappropriate speeding. At higher speeds, the amount of information to be processed increases and reaction times are reduced, increasing the expected severity of injuries in the event of a collision. (...)"
