Abstract
The human factor is a main cause of many accidents in which moped riders or cyclists are involved. Their lack of experience and their age are the main factors. The correlation which exists between the lack of safety and the characteristics of the traffic situation and in particular the provisions made for the moped riders and cyclists, is emphasized. It is shown that the effect of cycle tracks is favourable on road sections between junctions; that the effect of cycle tracks on junctions is different from that on road sections between the junctions, but not unfavourable per se; and that problems with the safety of cycle tracks are mainly related to moped riders.
