Sažetak
Occasional tragic accidents caused by semi-circular turning of vehicles on the passages in the median strips (central reserves) of motorways have instigated research on the Croatian motorway network. The results of the theoretical and practical research with the analysis of experience in the European countries have pointed out the need for a more serious approach to this issue. Preliminary results suggest standardization of forms, equipment and distance between passages. The official passages should be completely closed and emergency vehicles or vehicles for motorway maintenance should have to use lateral passages for changing of direction on the crossovers. On the basis of geometrical measuring and practice in some European countries it is recommended to design passages in the median strip of motorways for the traffic flow speed of 60 and 80 km/h. The length of the passages for the mentioned speeds is 90 or 135 m. In the respect of operative length of motorway sections for road construction works, distances between passages should be among 3 and 5 km.
