Conversion of a Semi-two Lanes Roundabout into a Turbo-roundabout: A Performance Comparison
Procedia Computer Science, 2016 AbstractIn the last years, as regards the functional design of at-grade intersections, near to classic layouts (signal-controlled junctions, roundabouts, etc.) a new solution has born: the “turbo-roundabout”. It is a canalized multilane oval intersection with a non-traversable or partially traversable center island and with a spiral circulatory ...

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 ...

Calculation of Turbo-Roundabouts with Slip Lanes
Applied Mechanics and Materials, 2013 A 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.

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).

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 ...
