The design should be manageable and interesting for all users and not exclude any users. It
should present equal facilities for everyone. For this principle, disabled people, old people, children, pregnants and women with children are to be thought primarily. For example, as very current accesses, many overpasses in Ankara have no elevators or staircases like the overpass at the entrance of METU or the subway exits at Sıhhiye in front of the Abdi İpekçi Park. Moreover, like many others, the portable toilets which are necessary with no doubt have no special toilet cabins for disabled people.
