Conflict Models for Single-Lane Roundabout Slip Lanes from Microsimulation

open access: yes, 2011
Conflict patterns at single-lane roundabouts with and without slip lanes were evaluated and compared through VISSIM, the microscopic simulation program for multimodal traffic flow modeling, and surrogate safety assessment model (SSAM) analysis.

Proposal for the reconstruction of a two-lane roundabout with capacity and traffic-safety analysis [PDF]

open access: yes, 2018
Krožna križišča so križišča, kjer prednostna cesta poteka v zaključenem krogu, promet pa se odvija v nasprotni smeri gibanja urnih kazalcev. Razvila so se kot alternativa klasičnim križiščem in imajo številne prednosti.

Robustness of roundabout metering systems (RMS)

open access: yes, 2014
A simple explorative study shows that roundabouts are too small to be equipped with permanently operating traffic lights. The conclusion of a recent, more detailed study was not fundamentally different to this: at a small two-lane roundabout with four ...

Guidelines for the Conversion of Urban Four-Lane Undivided Roadways to Three-Lane Two-Way Left-turn Lane Facilities, April 2001 [PDF]

open access: yes, 2001
Four-lane undivided roadways in urban areas can experience a degradation of service and/or safety as traffic volumes increase. In fact, the existence of turning vehicles on this type of roadway has a dramatic effect on both of these factors.

Toolbox of Countermeasures for Rural Two-Lane Curves, June 2012 [PDF]

open access: yes, 2012
The Federal Highway Administration (FHWA) estimates that 58 percent of roadway fatalities are lane departures, while 40 percent of fatalities are single-vehicle run-off-road (SVROR) crashes.

Capacity of Small Roundabouts with Two-Lane Entries

open access: yes, 2006
Roundabouts have been a popular system for intersections outside downtown zones in urban areas in Switzerland for more than 10 years. One form of small roundabout becoming more common in Switzerland is the system with short two-lane approaches and a ...

Comparative Study of Signal Control Models for Roundabouts

open access: yesIEEE Access
Traffic signal is one of the control approaches used for roundabouts. Although many models are used for signalized roundabouts, studies involving their comparative analysis are insufficient.
