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 ...

Performance Analysis of Basic Turbo-Roundabouts in Urban Context
Procedia, Social and Behavioral Sciences, 2012 AbstractA turbo roundabout is a new type of canalized multilane intersection in which the physical separation between lanes helps to prevent side collisions when crossing the roundabout. This paper presents an estimation of capacity, delays and level of service of basic turbo roundabouts in undersaturation conditions, considering both vehicle flow and ...

A safety analysis of roundabouts and turbo roundabouts based on Petri nets [PDF]
Traffic Injury Prevention, 2019 Objective: In this work, a roundabout and a turbo roundabout model are compared and previous modeling with continuous Petri nets and safety are analyzed through indicators of complexity. Petri nets are a graphic and mathematical representation that allow a faithful modeling of urban systems.

Calculation of Turbo-Roundabouts with Slip Lanes
Applied Mechanics and Materials, 2013A turbo roundabout is a particular type of roundabout where all lanes are bounded by traffic signs and by non-mountable curbs installed at entering and circulating lanes. Turbo roundabouts also have a very particular shape to accomplish the splitting of traffic streams and to prevent cars weaving through.
