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 ...

Comparative Analyse of the Two New Alternative Types of Roundabouts – Turbo and Flower Roundabout
The Baltic Journal of Road and Bridge Engineering, 2014 Alternative types of roundabouts are usually more recent and have been implemented only in certain countries. Typically, they differ from “standard” roundabouts in one or more design elements, whilst the purposes of their implementations are also ...

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 ...

Case Study: Capacity Characteristics Comparison of Single-lane Roundabout and Turbo-roundabouts
Procedia Engineering, 2017 Abstract Turbo-roundabouts are new type of roundabouts that recently become more popular for their significant advantages. Due to their specific geometry of spiral leading circulatory lanes and raised lane dividers provide a high level of traffic safety while a relatively large capacity maintain.

Problems of ensuring traffic flow on a Basic turbo roundabout with non-standard curvilinear entries (a case study) [PDF]
Przegląd Komunikacyjny, 2023 : With ever-increasing motorisation and the desire for greater traffic safety, conventional roundabouts and turbo roundabouts are being designed. Turbo roundabouts provide greater traffic safety than conventional roundabouts due to the segregation of ...

Safety Evaluation of Turbo Roundabout Considering Autonomous Vehicles Operation [PDF]
Archives of Civil Engineering, 2021 A microsimulation approach was carried out in this paper to evaluate the safety performance of turbo roundabouts in which the "CAVs" of connected autonomous vehicles are mixed with the "CVs" of conventional vehicles the research aims to evaluate the ...

Turbo roundabout - An alternative to classic two lane roundabout
Put i saobraćaj, 2023 Traffic congestion and the questionable safety of two-lane roundabouts are two justified criteria for the introduction of turbo roundabouts. The increase in capacity, which also results in an increase in the level of service, is a positive aspect of this alternative type of roundabout.

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.
