Abstract
Generally, young children are able to comply with rules such as "don't cross when traffic is approaching".However, as children grow older this relatively simple strategy often cannot be applied. They more often encounter traffic situations in which it is no longer possible to wait until the road is completely clear. In order to speed up a spontaneous learning process by trial- and- error, a training method for primary school children was developed. The results indicated that the decisions of the experimental group improved.In particular, the number of positive crossing decisions in cases in which only a few seconds were left until the passage of an approaching car diminished considerably.
