Since the arrival of the automobile, pedestrian mobility has been considerably reduced in favour of mechanical means of transport. The average pedestrian nowadays travels an average daily distance not exceeding 10 km. Nevertheless, pedestrians, as vulnerable users, i.e. not protected by a bodyshell and therefore more sensitive to impacts and collisions, are particularly exposed to the risk of accidents.

The main categories of pedestrians affected by the accident are people aged 75 and over, in urban areas and during the day, as well as pedestrians aged 18 to 44, at night, on roads outside urban areas and on motorways. In urban areas, pedestrian accidents occur mainly during the day (67% of deaths), while outside urban areas, accidents occur mainly at night (78% of deaths on roads outside urban areas and 81% of deaths on motorways). As the population over 65 years of age increases each year, predictions of the accident rate of this category of users today pose a real public health challenge, especially when we consider that the elderly represent the largest proportion of pedestrians.

Children (0-13 years old) and adolescents (14-17 years old), as pedestrians, are also strongly affected by this type of accident. In three quarters of the cases, the accident occurs less than 500m from the school and in an environment used every day by the victim.
