Case Study: Capacity Characteristics Comparison of Single-lane Roundabout and Turbo-roundabouts
Procedia Engineering, 2017 Abstract Turbo-roundabouts are new type of roundabouts that recently become more popular for their significant advantages. Due to their specific geometry of spiral leading circulatory lanes and raised lane dividers provide a high level of traffic safety while a relatively large capacity maintain.

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

New Type of Roundabout: Roundabout with “Depressed” Lanes for Right Turning – “Flower Roundabout”
Promet (Zagreb), 2011 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 ...

Signalized Turbo Roundabouts: A Study into the Applicability of Traffic Signals on Turbo Roundabouts
, 2013 Since the 1980s, the modern single-lane roundabout has been applied in the Dutch road network. The roundabout offered major safety benefits compared to the conventional signalized intersection, however, it also required more space.
