Analysis of Kinematic Parameters and Driver Behavior at Turbo Roundabouts

Journal of Transportation Engineering, Part A: Systems, 2018
AbstractThis study focuses on both vehicle kinematic parameters (speed and acceleration) and behavior parameters (critical interval and follow-up time) of drivers at turbo-roundabouts.

Evaluating Capacity and Efficiecy of Turbo-Roundabouts

2009
Recent evolution of roundabout design has been directed towards the so-called turbo-roundabout, with the aim of ensuring better safety conditions than those afforded by traditional schemes. The few turbo-roundabout installations so far implemented have not allowed sufficient research in order to analyze operational conditions and capacity models ...

Estimation of turbo-roundabout capacity

2016
In recent years, a new estimation method of lane capacity at turbo-roundabouts entries in various countries has been developed. It can be shown that methods developed under different assumptions and taking into account various factors determining capacity give significantly different results. Different approaches to the estimation of capacity are used,

CONVERSION OF A SEMI-TWO LANE ROUNDABOUT INTO TURBO ROUNDABOUT: A SAFETY ANALYSIS

2014
Roundabouts have become a common type of intersection in different countries because they contribute to improve traffic safety and to reduce environmental impacts. Moreover, among all types of intersections and with respect to conventional roundabouts, turbo-roundabouts have been proven to offer higher safety levels in particular traffic conditions by ...

Investigating the Conversion of a Signalized Intersection to a Turbo Roundabout

Turbo roundabouts are multilane roundabouts with helical pavement markings and raised structures. While they have seen widespread use in Europe, California is only the second state in the U.S. (after Florida) to have installed a turbo roundabout. Turbo roundabouts separate the ingress and circulating roadways.
