Performance Evaluation of Basic Turbo Roundabouts as an Alternative to Conventional Double-Lane Roundabouts

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 ...

Comparative Analysis of Compact Multilane Roundabouts and Turbo-Roundabouts

Journal of Transportation Engineering, 2010
This 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.

Modern Suburban Roundabouts in Croatia - Flower and Turbo roundabouts

Scientific journal of civil engineering, 2019
Turboroundabouts 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.

Turbo Roundabout Usage in Lieu of Conventional Roundabouts for the Jordanian Traffic Conditions

International Journal of Civil Engineering, 2018
The 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).

Evaluating Capacity and Efficiecy of Turbo-Roundabouts

2009
Recent 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 ...

CONVERSION OF A SEMI-TWO LANE ROUNDABOUT INTO TURBO ROUNDABOUT: A SAFETY ANALYSIS

2014
Roundabouts have become a common type of intersection in different countries because they contribute to improve traffic safety and to reduce environmental impacts. Moreover, among all types of intersections and with respect to conventional roundabouts, turbo-roundabouts have been proven to offer higher safety levels in particular traffic conditions by ...

Investigating the Conversion of a Signalized Intersection to a Turbo Roundabout

Turbo roundabouts are multilane roundabouts with helical pavement markings and raised structures. While they have seen widespread use in Europe, California is only the second state in the U.S. (after Florida) to have installed a turbo roundabout. Turbo roundabouts separate the ingress and circulating roadways.
