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.

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 ...

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 ...

Enhancing Intersection Efficiency: A Comparative Analysis of Converting Single-Lane Roundabout to Turbo Roundabout. [PDF]
Sensors (Basel)This paper evaluates the operational and safety performance of a conventional single-lane roundabout (SLR) and a turbo roundabout (TR) using a mixed-methods approach. Field traffic counts and turning-movement matrices were collected at the studied intersection in Pezinok (Slovakia).

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 ...
