Public places and areas for facilities other than buildings shall be designed to be useful for persons with reduced mobility or orientation. For open spaces, specific guidance paths shall exist. Even in existing public places, obstacles in the form of a lack of contrast markings and warning markings must be remedied.
Contrasts and markings in buildings: “For people with reduced orientation, it should be easy to find and access important target points such as walkways, stairs, ramps and actuators. In public spaces (open spaces) such as receptions and foyers, there should be continuous tactile and guidance paths.”
