Dynamic noise modeling at roundabouts

Signals and Meters at Roundabouts

With the emergence of the modern roundabout as an effective form of traffic control in the United States, more and more information is needed when situations arise in which additional traffic control is required. The signalization and metering of roundabouts can relieve congestion during peak hours of the day as well as possibly provide safer access for pedestrians and cyclists. Although the si...

V2V-Intersection Management at Roundabouts

More than 44% of all automotive crashes occur in intersections. These incidents in intersections result in more than 8,500 fatalities and approximately 1 million injuries each year in USA [1,18]. It is also established that roundabouts are safer than junctions. According to a study of a sampling of roundabouts in the United States, when compared with the junctions they replaced, roundabouts hav...

Modeling and Calibrating Capacity of Large Roundabouts

Roundabout models, available in the literature widely, vary between one method and another. Majority of the models are solely based on circulating fl ow to estimate capacity. The relationship between maximum entry fl ow of large dual and triple lane roundabouts and their geometric and traffi c characteristics is investigated here for saturated fl ow condition using multivariate analysis. The de...
