Traditionally, the objective of the regulation was to attend tothe growing increase in the use of motor vehicles (mainly cars), and for this reason, it wasthe protagonist in most of the articles of the General Traffic Regulations. Today, in manycities, the car is no longer the protagonist and shares the space on the streets, not only withother motor vehicles as buses or motorcycles, but also with pedestrians, bicycles, electricpedal-assisted cycles (EPAC), personal mobility vehicle (PMV), …Pedestrian mobility is becoming more and more important every day but the number ofpedestrians that died inside Spanish urban areas in road accidents is almost 50% of totalurban areas road fatalities. In this sense, the mobility and road safety policies developed bylocal administrations have to focus on the objective of the reduction of accidents and theirseverity involving pedestrians and other vulnerable users in urban areas.This article collects studies and experiences in other countries that show the effects ofreducing the speed of motor vehicles in urban areas in order to reduce accidents and/or theirseverity if they occur. It also analyzes other options that reinforce this measure and that couldhelp reduce this problem. PB Universidad de Burgos.
