In order to create human settlements that satisfy the population's needs, we first need to take into serious account man's movement in space as it has been transformed throughout the centuries. Man's movement has passed several stages, from relying solely on his physical strength to the use of automobiles. However, today there is a loss of equality in movement and transportation, based mainly on class differences, since humanity has failed to readjust its physical and social structure when coping with the problem of modern settlements. In order to re-establish order in human settlements, people need to avoid pollution, to create an urban environment friendly to the inhabitants, and to increase the efficiency of public transportation means.
