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.

Transportation Research Record: Journal of the Transportation Research Board, 2021
Since their introduction in the late 1990s, basic turbo roundabouts have made a great success in several European countries. Researchers, however, have been unable to reach a general consensus on the operational performance advantages and benefits derived from such a novel design of multi-lane roundabouts, as compared with conventional double-lane ...

Modern Suburban Roundabouts in Croatia - Flower and Turbo roundabouts
Scientific journal of civil engineering, 2019Turboroundabouts 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.

Comparative Analysis of Compact Multilane Roundabouts and Turbo-Roundabouts
Journal of Transportation Engineering, 2010This paper presents a comparative analysis of the traffic performances of turbo-roundabouts and roundabouts in terms of capacity and delays. We chose to use a recent German procedure for roundabouts included in “Kreisel” software as our calculation procedure to determine the capacity of turbo-roundabouts.

Capacity Increase through connectivity for the i-Roundabout and i-Turbo roundabout
2020 Forum on Integrated and Sustainable Transportation Systems (FISTS), 2020Is a roundabout still a good solution in the era where ‘intelligent’ intersection control using vehicle connection (i-TLC), is in upswing? To answer this question, the capacity of ‘i-roundabouts’, where the infrastructure communicates with the vehicles (I2V), is determined analytically.

Analysis of Kinematic Parameters and Driver Behavior at Turbo Roundabouts
Journal of Transportation Engineering, Part A: Systems, 2018AbstractThis study focuses on both vehicle kinematic parameters (speed and acceleration) and behavior parameters (critical interval and follow-up time) of drivers at turbo-roundabouts.

Evaluating Capacity and Efficiecy of Turbo-Roundabouts
2009Recent evolution of roundabout design has been directed towards the so-called turbo-roundabout, with the aim of ensuring better safety conditions than those afforded by traditional schemes. The few turbo-roundabout installations so far implemented have not allowed sufficient research in order to analyze operational conditions and capacity models ...
