Abstract
The surroundings of homes for the elderly are not adapted to them. In many places in many countries the elderly, who live in homes because they need extra care, have no opportunity to visit their friends in the same kind of institution at the other side of the road because it is a state road; a traffic-light with a press-button would be too disadvantageous to drivers. They might get "impatient" with fatal results. Will an elderly person not get impatient with fatal results?
