Abstract
This publication contains four papers: 1. "Zoals de ouderen zongen piepen de jongen".- In spite of all efforts to traffic education parents and educators have to realize that children's behaviour always will be incalculable, and that children always need to be protected and looked after. 2. "Kleuter en Verkeer"- Children have to be excluded from the street; they have to play on playgrounds. 3. "De gevaarlijke straat"- Investigation into the way children are involved in dangerous traffic situations. 4. "Stoeprand-stop-pleintje" op de speelplaats- Traffic situations should not be simulated on playgrounds, because children consider them as a play.
