Sažetak
Today's urban space offers little space for possible traffic solutions of the intersections, especially when it comes to city centres. Possible solutions, which do not require great area, are mini-roundabouts. They are characterized by transit central island, around which passenger vehicles (and other small sizes vehicles) operate as in the other roundabouts, while long vehicles (buses, trucks, etc.) operate as in classic intersections at level, crossing fully or partly over the central island. This type of roundabouts is usually carried out in populated areas, as a measure to calm traffic or as a solution to increase the capacity of existing classic intersection or intersection with traffic lights. Many studies have shown that the application of this type of intersection has significantly increased the capacity of the intersection and reduced the number of traffic accidents. Traffic calming and relatively low construction costs are considered to be significant positive feature of these intersections. However, in case of application of mini-roundabouts as traffic calming measures it is necessary to be careful because a roundabout without a raised central island may be poorly visible for drivers of passenger cars and thus may increase the risk of accidents. In such cases, special attention should be given to street lighting and other elements to calm traffic at the approach to the intersection. In the case of a large number of pedestrians and cyclists, mini-roundabouts are poorer solutions compared to classic intersections because at classic intersections their crossing is usually protected by traffic lights. This paper will compare the guidelines for the performance of mini-roundabouts of other states, because the Croatian guidelines do not deal with this type of intersection, even though there are many mini-roundabouts in Croatia already built.
