Assessing Vehicle Emissions from a Multi-Lane to Turbo Roundabout Conversion Using a Microsimulation Tool

open access: yesEnergies, 2021
The development of urban strategies for the reduction of environmental impacts and decarbonization requires ongoing monitoring from the local scale and further deployment of actions to improve transport demand (user characteristics and modal choice) and ...

A safety analysis of roundabouts and turbo roundabouts based on Petri nets [PDF]

open access: yesTraffic 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.

Performance Analysis of Basic Turbo-Roundabouts in Urban Context

open access: yesProcedia - Social and Behavioral Sciences, 2012
AbstractA turbo roundabout is a new type of canalized multilane intersection in which the physical separation between lanes helps to prevent side collisions when crossing the roundabout. This paper presents an estimation of capacity, delays and level of service of basic turbo roundabouts in undersaturation conditions, considering both vehicle flow and ...

Comparing Performances of Turbo-roundabouts and Double-lane Roundabouts

open access: yesModern 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.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer 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 ...

THE APPLICATION OF HCM 2010 IN THE DETERMINATION OF CAPACITY OF TRAFFIC LANES AT TURBO ROUNDABOUT ENTRIES [PDF]

open access: yesTransport Problems, 2016
The main aim of this study was to verify whether it is possible to utilize the model contained in the HCM 2010 methodology for evaluation of traffic capacity of the lanes at the entries to turbo roundabouts in Poland. The models contained in the HCM 2010

Indium‐Free Silicon Heterojunction Solar Cells: Achieving High Conductivity With Magnetron‐Sputtered SnO2

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Amorphous SnO2 films with low resistivity (~1.2 × 10−3 Ωcm) were realized by low‐temperature magnetron sputtering through control of O2 flow ratio, substrate temperature, and H incorporation. Si heterojunction solar cells incorporating these films achieved a conversion efficiency of 21.1%, approaching that of cells based on MS‐ITO and RPD‐SnO2 ...
