Abstract
The introduction of a continuous timetable in primary schools in combination with a later time of opening of these schools in the morning can result in a reduction of 130 severely injured children per year in the Netherlands. There is little recent quantitative information on the traffic mobility of children in the age range of 0 - 12 years and research should be carried out on such questions as how children travel to school, how many kilometres they have to travel, whether they are given guidance when playing outside etc. Changes in timetables in secondary schools can also have a positive effect on the traffic safety of children.
