HETEROGENEOUS TRAFFIC FLOW MODEL FOR A TWO-LANE ROUNDABOUT AND CONTROLLED INTERSECTION
International Journal of Modern Physics C, 2007Modern urban traffic management depends heavily on the efficiency of road features, such as controlled intersections and multi-lane roundabouts. Vehicle throughput at any such configuration is modified by traffic mix, by rules governing manoeuvrability and by driver observance, as well as by traffic density.

Transportation Research Record: Journal of the Transportation Research Board, 2017
In the United States, roundabouts have recently been constructed to replace signalized intersections at freeway ramp terminals as both a safety and an operational treatment. In practice, this treatment is in need of guidelines specifying conditions when the roundabout or signalized intersection is more appropriate to assist practitioners in deciding ...

Capacity of Small Roundabouts with Two-Lane Entries
Transportation Research Record: Journal of the Transportation Research Board, 2006Roundabouts 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 single-lane extrawide circulatory roadway.

Conceptual Multi-criteria Analysis of Road Traffic Safety Improvement for a Two-Lane Roundabout
2018The aim of this study is to provide a detailed analysis of causes of road traffic low safety level on two-lane roundabouts, on the example of “Ofiar Katastrofy Smolenskiej” roundabout situated in Olsztyn and an analysis of the most convenient alteration of the roundabout in order to improve its safety.

Compact two-lane roundabouts are increasingly popular. Designing cycle lanes at two-lane roundabouts may not benefit motor vehicles, pedestrians and cyclists simultaneously. This study addresses environmental and operational aspects for accommodating bicycle treatments at compact two-lane roundabouts, namely: (i) sharing bicycles with the motor vehicle

Aspects of traffic safety of two-lane roundabout
2015Significant improvement of functional characteristics of roundabout in relation to the classic intersections is unquestionable, but the goal of this research is to analyse the safety features of the two-lane roundabout. Traffic safety is a significant issue for the economy of a region, so application of traffic solutions that deliver greater safety of ...

CONVERSION OF A SEMI-TWO LANE ROUNDABOUT INTO TURBO ROUNDABOUT: A SAFETY ANALYSIS
2014Roundabouts have become a common type of intersection in different countries because they contribute to improve traffic safety and to reduce environmental impacts. Moreover, among all types of intersections and with respect to conventional roundabouts, turbo-roundabouts have been proven to offer higher safety levels in particular traffic conditions by ...

A considerable number of two-lane roundabouts is used in Poland today. Observations of the behaviour of drivers who drive through this type of intersections show that the lanes in the area of the intersection are not equally loaded. Drivers are more willing to use the right traffic lane at the roundabout’s inlet, even if traffic intensity is ...
