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.

Comparative Analysis of "Turbo", "Reduced-Turbo", "Flower" and "Semi-Turbo" Roundabout
Tehnički 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
Frontiers 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
Civil 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.

Microsimulation-based passenger car equivalents for heavy vehicles driving turbo-roundabouts
Transport, 2016 Due to its geometric design, turbo-roundabouts impose greatest constraints to the vehicular trajectories; by consequence, one can expect a more unfavourable impact of heavy vehicles on the traffic conditions than on other types of roundabouts.
