Moving from Conventional Roundabouts to Turbo-roundabouts [PDF]
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

Comparing Performances of Turbo-roundabouts and Double-lane Roundabouts
Modern Applied Science, 2012 Starting from assumptions regarding the arrival process of circulating streams and according to models based on the gap-acceptance theory, the paper is aimed at comparing operational performances between basic turbo-roundabouts and double-lane roundabouts.

Geometric design of turbo roundabouts [PDF]
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 ...

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 ...

Capacity of normal and turbo-roundabouts: comparative analysis [PDF]
Proceedings of the Institution of Civil Engineers - Transport, 2014 While researchers agree as to the safety benefits of turbo-roundabouts, their improvements in terms of capacity and delay remain open to discussion. This is mostly because previous research is based on capacity models that do not fully describe the complex interactions between traffic streams on multi-lane roundabouts.

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 ...
