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

The Passenger Car Equivalent Factors for Heavy Vehicles on Turbo Roundabouts
Frontiers in Built Environment, 2019 The presence of heavy and slower vehicles within the traffic stream significantly reduces traffic capacity. This reduction increases with the higher participation of heavy vehicles in the stream, which, compared to passenger cars, move at a lower speed ...

Performance Analysis of Basic Turbo-Roundabouts in Urban Context
Procedia, Social and Behavioral Sciences, 2012 AbstractA turbo roundabout is a new type of canalized multilane intersection in which the physical separation between lanes helps to prevent side collisions when crossing the roundabout. This paper presents an estimation of capacity, delays and level of service of basic turbo roundabouts in undersaturation conditions, considering both vehicle flow and ...

International Journal of Transportation Science and TechnologyThis article presents a methodology to estimate the entry capacity (EC) and total capacity (TC) of basic turbo roundabouts under partial and fully connected and autonomous vehicle (CAV) environments. EC calculations are partially based on capacity models

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 ...

Safety Evaluation of Turbo Roundabout Considering Autonomous Vehicles Operation [PDF]
Archives of Civil Engineering, 2021 A microsimulation approach was carried out in this paper to evaluate the safety performance of turbo roundabouts in which the "CAVs" of connected autonomous vehicles are mixed with the "CVs" of conventional vehicles the research aims to evaluate the ...

Turbo roundabout - An alternative to classic two lane roundabout
Put i saobraćaj, 2023 Traffic congestion and the questionable safety of two-lane roundabouts are two justified criteria for the introduction of turbo roundabouts. The increase in capacity, which also results in an increase in the level of service, is a positive aspect of this alternative type of roundabout.

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).

Geometric design of turbo roundabouts
Tehnicki 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 ...
