Samenvatting
Since 1969 there has been an increase in the popularity of the bicycle. As a result, not only have bicycle/motor vehicle collisions been on the rise, but major shifts have occurred in the age distribution of victims. Age-specific critical behaviours of the bicyclists as a basis for countermeasure development with regard to age are presented. Countermeasure activity that addresses these critical behaviours exists only to a limited extent, particularly in the teenage and young adult areas.
