In this paper the performance level of basic turbo-roundabouts and double-lane roundabouts are compared.

Results of the analyses show that efficiency of basic turbo-roundabouts highly depend on traffic situations and can be significant when major road captures most of the traffic demand

Abstract

In this paper the performance level of basic turbo-roundabouts and double-lane roundabouts are compared. Cowan’s M3 headway distribution was chosen to take into account bunched vehicles moving along each circulating lane; the Hagring model 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 the intersection. Results of the analyses show that efficiency of basic turbo-roundabouts highly depend on traffic situations and can be significant when major road captures most of the traffic demand
