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.

Analyses of maximum-speed path definition at single-lane roundabouts
Journal of Traffic and Transportation Engineering (English ed. Online), 2018 The process of designing roundabouts is an iterative process through which, in several checks, the design elements of a roundabout get optimized. Existing regulations for roundabouts involve swept path analyses, sight distance analyses and speed analyses

A Roundabout Way to Cancer [PDF]
, 2012 The Slit family of secreted proteins and their transmembrane receptor, Robo, were originally identified in the nervous system where they function as axon guidance cues and branching factors during development. Since their discovery, a great number of additional roles have been attributed to Slit/Robo signaling, including regulating the critical ...

Improving cycling safety through infrastructure design: A bicycle simulator study
Transportation Research Interdisciplinary Perspectives, 2023 This study investigated the impact of two road treatments on cyclist behaviour using an bicycle simulator. The treatments were sharrows (presence or absence) at a roundabout and widening an on-road bike lane (width 1.2 m or 1.8 m) on a curved mid-block ...

A Roundabout Way to the Niche [PDF]
Cell Stem Cell, 2011 A new player in hematopoietic stem cell (HSC)-niche interactions is introduced in this issue of Cell Stem Cell. Smith-Berdan et al. (2010) demonstrate that Robo4 is involved in HSC engraftment and mobilization and does so in cooperation with Cxcr4 to guide stem cells to and secure them in the niche.

A simulation of traffic noise emissions at a roundabout based on a cellular automaton model
Acta Acustica, 2021 The calculation and evaluation of traffic noise is an important task in urban road design. Roundabouts are a common form of urban road intersection. The complexity of traffic operations makes the calculation of traffic noise near a roundabout challenging.
