Risultato della ricerca: Articlepeer review

Abstract

In this paper the performance level of basic turbo-roundabouts and double-lane roundabouts are compared. Cowan’s M3headway distribution was chosen to take into account bunched vehicles moving along each circulating lane; the Hagringmodel was adopted to evaluate entry capacity both at turbo-roundabout and at double-lane roundabout.The comparative analysis was performed evaluating operational performances in terms of delay suffered by users entering theintersection.Results of the analyses show that efficiency of basic turbo-roundabouts highly depend on traffic situations and can besignificant when major road captures most of the traffic demand
