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 ...

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

Modern suburban roundabouts in Croatia - flower and turbo roundabouts
Scientific Journal of Civil Engineering, 2020Turboroundabouts are specially designed multilane roundabouts with spiral circulatory roadway and physically separated traffic lanes. This roundabout layout was developed in the late nineties of the last century with the aim of increasing the traffic safety and capacity at classic multi-lane roundabouts.

Safety and Efficiency Analysis of Turbo Roundabout with Simulations Based on the Lujiazui Roundabout in Shanghai [PDF]
Sustainability, 2020 Traditional multilane roundabouts have many branch lanes without traffic signs and channelization, which leads to a high tendency for traffic collisions. Turbo roundabouts are a new design that has the potential to reduce lane-change conflicts using canalization to force drivers to keep in specific lanes based on their intended destination.

Transportation Research Record: Journal of the Transportation Research Board, 2009
The Dutch turbo roundabout is characterized by predictable lane use and radial connecting entries. To calculate the capacity, in 1997 the multilane roundabout explorer was developed by modification of the capacity model of Bovy, which considered both separated lanes and pseudoconflict.

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.

An Analysis of Turbo Roundabouts from the Perspective of Sustainability of Road Transportation [PDF]
Sustainability, 2021 The designs of turbo roundabouts vary among countries and undesirable and potentially dangerous situations can occur for vehicles passing through the roundabout. In this article, we focus on an analysis of one of the problems within sustainable road transportation, i.e., the geometric layout of turbo roundabouts.

Turbo Roundabout Usage in Lieu of Conventional Roundabouts for the Jordanian Traffic Conditions
International Journal of Civil Engineering, 2018The main objective of this study is to check the possibility of upgrading at-grade roundabouts to Turbo roundabouts considering the Jordanian driving conditions. It is also to check how such upgrade is going to affect performance measures of the studied areas including safety, capacity, queue length, delay, and level of service (LOS).

Turbo Roundabouts: Design, Capacity, and Comparison With Alternative Types of Roundabouts
2021Introduction. In turbo roundabouts traffic entry, exit, and circulatory lanes are physically delimited by kerbs (see Fig. 1A). This implies a lowerNnumber of potentially conflicting points (Fig. 1B) between vehicle trajectories than conventional roundabouts (Fortuijn, 2009). By way of an example, in a turbo roundabout with four arms and two circulatory
