Abstract
The Yugoslav traffic experts follow with great interest the development of motorisation and the effect of such development in other countries, especially new experience in the sphere of traffic regulation and accident prevention. We believe that mutual direct contacts between experts and the exchange of opinion, experience and working methods are a very useful form of international cooperation, as the past work on the meetings of the International Study Week in Traffic and Safety Engineering has already proved. Our specialists have participated and attentively followed the work on these meetings that are held every second year.
