Flower Roundabouts And Double-Lane Roundabouts: A Comparative Performance Analysis
Archives of Civil Engineering, 2014 In the paper, a choice criterion between flower roundabouts and double-lane roundabouts is proposed, focusing on operational benefits that can derive from one scheme over the other, and outlining a general framework for benefit-cost analysis. In order to

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.
