MODERN TURBO-ROUNDABOUTS AND THEIR DESIGNING IN THE CZECH REPUBLIC

open access: diamondJurnal Teknologi, 2016
Even though the turbo roundabouts have been designed in the Czech Republic since the beginning of this century, until the middle of 2015, there was no national regulation which would describe the way of their construction. As a result of this, there are only 10 turbo-roundabouts with various widths of design elements and different traffic signs in the ...

Turbo roundabout - An alternative to classic two lane roundabout

open access: yesPut 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]

open access: yesScientific 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).

Estimation of Air Pollutant Emissions in “Turbo” and in Conventional Roundabouts

open access: hybrid, 2013
The road pollutant emissions, above all in urban context, are correlated to many infrastructural parameters and to traffic intensity and typology. The research work on road junction geometry, carried out in European research centres, has recently ...

Basic Turbo Roundabouts as an Alternative to Conventional Double-lane Roundabouts: Operational Performance Evaluation

open access: green, 2019
Conventional roundabouts have been prevalent worldwide since the emergence of modern roundabouts in 1966. An innovative design of multilane roundabouts known as turbo roundabouts, however, has been recently introduced as an alternative to conventional ...

Multi-lane Roundabout Capacity Evaluation

open access: yesFrontiers in Built Environment, 2017
Although two-lane roundabouts theoretically exhibit excellent operating performance, in practice, safety problems arise because of inappropriate driving behavior.

Conversion of Existing Roundabouts into Turbo-Roundabouts: Case Studies from Real World [PDF]

open access: hybridJournal of Civil Engineering and Architecture, 2012
Compared with roundabouts the main advantages of turbo-roundabouts are the reduction in the number of potential conflicting points and the lower speed of vehicles passing through the intersection, they both can improve safety conditions at the junction. Moreover, the physical delimitation among lanes limits the side-by-side accident risk. These aspects

Performance Evaluation of a Hybrid Roundabout Using a Microscopic Simulation

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2021
Roundabouts are one of the safest types of intersections. There are a number of roundabout types in literature. Each roundabout type is distinguished by some characteristics.

Safety and Efficiency Analysis of Turbo Roundabout with Simulations Based on the Lujiazui Roundabout in Shanghai [PDF]

open access: yesSustainability, 2020
Traditional multilane roundabouts have many branch lanes without traffic signs and channelization, which leads to a high tendency for traffic collisions. Turbo roundabouts are a new design that has the potential to reduce lane-change conflicts using canalization to force drivers to keep in specific lanes based on their intended destination.
