Intersection Sight Distance Characteristics of Turbo Roundabouts [PDF]
Designs, 2021 A turbo roundabout uses spiral circulatory roads for effectively counteracting the problems faced in modern multilane roundabouts. First developed in 1996, the turbo roundabout has an advantage over the conventional roundabout regarding capacity and ...

Performance Assessment of Turbo-roundabouts in Corridors
Transportation Research Procedia, 2015 AbstractThere is a widespread agreement in the scientific community that the transformation of a conventional multi-lane roundabout into a turbo-roundabout results in a significant increase of road safety levels. However there is no consensus regarding its effect in terms of capacity, as there are some authors that point towards a small reduction in ...

Moving from Conventional Roundabouts to Turbo-roundabouts
Procedia, Social and Behavioral Sciences, 2014 AbstractThis paper introduces the turbo-roundabout concept and compares its performance with the conventional double-lane roundabout in terms of safety and capacity. While researchers agree as to the safety benefits of turbo-roundabouts, improvement in terms of capacity is still open to discussion. The application of a new calculation method shows that

Turbo-roundabouts vs Roundabouts Performance Level
Procedia, Social and Behavioral Sciences, 2012 AbstractIn 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 ...
