Optimization of Traffic at Uncontrolled Intersections: Comparison of the Effectiveness of Roundabouts, Signal-Controlled Intersections, and Turbo-Roundabouts

open access: yesUrban Science
This study focuses on optimizing traffic flow at uncontrolled intersections by comparing the effectiveness of different intersection types: roundabouts, signal-controlled intersections, and turbo-roundabouts. The purpose is to determine which type offers

The Surrogate Safety Appraisal of the Unconventional Elliptical and Turbo Roundabouts [PDF]

open access: yesJournal of Advanced Transportation, 2018
Double-lane roundabouts have been created in many European countries over the past few centuries and are now characterized by an unsafe geometric development and by a low sustainability capacity or level.

The Passenger Car Equivalent Factors for Heavy Vehicles on Turbo Roundabouts [PDF]

open access: yesFrontiers 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 ...

UNDERSTANDING DRIVER BEHAVIOR IN NAVIGATING TURBO ROUNDABOUTS

open access: yes
Thesis (M.S.)--Michigan State University. Civil Engineering - Master of Science, 2025Turbo roundabouts minimize weaving conflicts by introducing raised lane separators within the circulating lanes compared to conventional multi-lane roundabouts. Although

Sustainable transport safety : are turbo roundabouts applicable to Canada?

open access: yes
As relatively novel intersections, roundabouts have garnered support and interest from many countries due to traffic flow and safety improvements over traditional intersections. Despite growing application, knowledge and experience is relatively scarce within Canada for multilane roundabouts (MLR’s); the Canadian Roundabout Design Guide was only ...

Multi-criteria comparative assessment of unconventional roundabout designs

open access: yesInternational Journal of Transportation Science and Technology, 2022
Roundabout design has been evolving to include versatile types that target specific characteristics of each considered location. They started addressing maneuverability issues and directional splits, among other factors.

Turbo-roundabouts: a model to evaluate capacity, delays, queues and Level of Service

open access: yes, 2012
A turbo roundabout is a particular type of roundabout where entering and circulating lanes are bounded by traffic signs and by non-mountable curbs. The physical separation between lanes, both at entries and on the ring, helps to prevent side collisions crossing the roundabout.

Performance Assessment of Turbo-roundabouts in Corridors

open access: yesTransportation 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 ...

Estimation of Passenger Car Equivalents for Two-Lane and Turbo Roundabouts Using AIMSUN

open access: yesFrontiers in Built Environment, 2020
The paper addresses issues related to Passenger Car Equivalents (PCEs) at roundabouts. Compared to other road units, the curvilinear elements of roundabout geometric design may impose greater constraints on vehicular trajectories and have a significant ...
