Despite the growth of this field, there are still many issues to resolve. One of these issues is focused on achieving Accessible Cities. Accessibility is an element of life quality that is of universal interest, a right of all citizens, a determining factor of the liveability of cities, and an essential element in modern society. It provides security, comfort and autonomy to pedestrians, cyclists, public transport and private motor vehicle users, in its rational use. It is respectful of the urban fabric and should be approached from the many aspects that affect accessibility. In this case, our research focuses on the field of pedestrian mobility, particularly in the most vulnerable group of people with disability. It deals with the study of urban accessibility—urban streets and urban public open spaces—as a means to enhance their participation and contribution in all aspects of social life.Unfortunately, some spaces of the public built environment are not accessible enough. Pedestrian crossings with curb ramps on only one end, excessively narrow sidewalks and those occupied by street furniture, unsuitable slopes, lack of rest areas over excessively long distances or streets to ensure a leisurely pace, and a lack of markers or clear organization of different traffic flows are just some examples. Its design does not take into account the requirements of people with mobility difficulties and other physical or sensory limitations (of understanding, communication or perception).
