New Type of Roundabout: Roundabout with “Depressed” Lanes for Right Turning – “Flower Roundabout”
Promet - Traffic&Transportation, 2012 Recently, many of the foreign traffic-safety analyses point out the low level of traffic safety in multi-lane roundabouts. This problem is resolved in several ways in different countries; however, the solution, whereby the number of conflict points is diminished (e.g. turbo roundabout) has proven to be the most successful. However, the turbo roundabout

Comparative Analyse of the Two New Alternative Types of Roundabouts – Turbo and Flower Roundabout
The Baltic Journal of Road and Bridge Engineering, 2014 Alternative types of roundabouts are usually more recent and have been implemented only in certain countries. Typically, they differ from “standard” roundabouts in one or more design elements, whilst the purposes of their implementations are also ...

Capacity Limits of Basic Turbo-Roundabouts
Communications, 2016 Turbo-roundabouts with their specific design characteristics have become a suitable solution of a single-lane roundabouts capacity problem and a standard two-lane roundabouts safety problem.

Multi-lane Roundabout Capacity Evaluation
Frontiers in Built Environment, 2017 Although two-lane roundabouts theoretically exhibit excellent operating performance, in practice, safety problems arise because of inappropriate driving behavior.

Traffic Reorganisation in Large Roundabouts of Vilnius and its Influence on Traffic Safety
The Baltic Journal of Road and Bridge Engineering, 2020 Historically, there are several large roundabouts in Vilnius with traffic organisation and safety problems. Vilnius City Administration initiated changes on these large roundabouts in 2016, by introducing new traffic organisation schemes and using ...

Combined Phase Design Model for Multileg Roundabout Intersections
Journal of Advanced Transportation, 2022 Multileg roundabout intersections are widely used in urban areas worldwide. However, its traffic organization and signal control are very complicated in the case of large traffic flow, and the signal optimization methods for conventional intersections ...
