Effect of vehicle composition and delay on roundabout capacity under mixed traffic conditions [PDF]
Archives of Transport, 2016 Roundabouts are replacing conventional unsignalized intersections in many parts of the world (Polus and Shmueli, 1997). Capacity estimation is necessary for designing a new roundabout, to analyze and improve the existing roundabout facilities.

Intersection Sight Distance Characteristics of Turbo Roundabouts
Designs, 2021 A turbo roundabout uses spiral circulatory roads for effectively counteracting the problems faced in modern multilane roundabouts. First developed in 1996, the turbo roundabout has an advantage over the conventional roundabout regarding capacity and ...

Traffic Circulation Efficiency of Elliptical Roundabouts
ARO-The Scientific Journal of Koya University, 2023 This paper investigates the impact of geometry of central island of roundabout on operational performance in terms of delay and capacity measures. A roundabout with an elliptical central island having major and minor axes of 63 and 44m respectively was ...

A safety analysis of roundabouts and turbo roundabouts based on Petri nets [PDF]
Traffic Injury Prevention, 2019 Objective: In this work, a roundabout and a turbo roundabout model are compared and previous modeling with continuous Petri nets and safety are analyzed through indicators of complexity. Petri nets are a graphic and mathematical representation that allow a faithful modeling of urban systems.

Cooperative Roundabout Control Strategy for Connected and Autonomous Vehicles
Applied Sciences, 2022 Intersections in the urban network are potential sources of traffic flow inefficiency. Existing intersection control mostly adopts the “cross” flow pattern model, while the use of the roundabout circular flow pattern is rather sparse.

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.

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 ...
