Conversion of a Semi-two Lanes Roundabout into a Turbo-roundabout: A Performance Comparison [PDF]
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 ...

New Type of Roundabout: Roundabout with “Depressed” Lanes for Right Turning – “Flower Roundabout” [PDF]
Promet (Zagreb), 2011 Recently, many of the foreign traffic-safety analyses point out the low level of traffic safety in multi-lane roundabouts. This problem is resolved in several ways in different countries; however, the solution, whereby the number of conflict points is ...

Traffic Efficiency Evaluation of Elliptical Roundabout Compared with Modern and Turbo Roundabouts Considering Traffic Signal Control [PDF]
Promet (Zagreb), 2017 This paper compared the performance of elliptical roundabout with turbo and modern roundabouts. It considers the effects of increasing the central island radius and speed limit on delay and capacity.

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

Determinants of crash numbers and constellations at turbo roundabouts in Germany
Traffic Safety ResearchTurbo roundabouts are a relatively new design. Thus far, research on their safety has focused on comparisons with other types of intersection and the effects of physical lane dividers.

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 ...

Multi-criteria comparative assessment of unconventional roundabout designs
International Journal of Transportation Science and Technology, 2022 Roundabout design has been evolving to include versatile types that target specific characteristics of each considered location. They started addressing maneuverability issues and directional splits, among other factors.

Geometric design of turbo roundabouts
Tehnički vjesnik = Technical gazette, 2017 Turbo roundabouts are lately a more common choice in designing multilane roundabouts. First guidelines for geometric design of this particular roundabout layout were developed by a Dutch Information and Technology Platform CROW in 2008. Soon after, a number of European countries began to develop their own regulations on turbo roundabouts, adjusted to ...

A CASE STUDY ANALYSIS OF ROUNDABOUTS ENTRY CAPACITY LOCALISED ON ONE OF THE MAIN ROAD IN SOSNOWIEC CITY (POLAND) [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2019 This paper is a case study, which among other things includes the analysis of the three roundabouts entry capacity: a turbo- and two spiralroundabouts. These intersections are located in one of the main road localised in Sosnowiec city (Poland).
