Work zones and temporary traffic organization at roundabout - review of selected solutions

In many countries roundabouts are becoming an increasingly common element of transportation infrastructure. Therefore, like other elements of the infrastructure, they may be subject to periodic closures associated with i.e. modernization of infrastructure, maintenance of road signs and traffic safety devices or renovation of road surface. Such closures require implementation of temporary traffic organization. Due to unique features of roundabouts it appears that specific methods of organizing work zones at such objects should be developed. This paper contains a proposal of typology of temporary traffic organization at roundabouts and a review of possible solutions for each group.
