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.

Comparative Analysis of "Turbo", "Reduced-Turbo", "Flower" and "Semi-Turbo" Roundabout

open access: yesTehnički vjesnik, 2020
A growing number of studies, presented in scientific and professional literature, point out a poor traffic safety characteristic of "standard" two-lane roundabouts, and lower capacity than expected. These problems are resolved in different ways in different countries; however, the most successful solution has proven to be reducing the number of ...

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 ...

Capacity Model for Single-Lane Minor Entry at Turbo-Roundabouts

open access: yesCivil and Environmental Engineering, 2021
Spirally arranged and physically separated traffic lanes in the circulatory carriageway of turbo-roundabouts force drivers to choose a particular entry lane and, subsequently, a circulatory traffic lane according to their intended destination.
