A methodology for calibrating and validating VISSIM simulation model is presented that
allows to replicate the observed vehicles conflicts. A roundabout case study has been …

In the last years, as regards the functional design of at-grade intersections, near to classic
layouts (signal-controlled junctions, roundabouts, etc.) a new solution has born: the “turbo …

Many researchers have shown in recent studies how roundabouts speed distribution,
together with other features (entering flow, circulating flow, entry curvature, entry path radius …

In the literature, many analytical techniques allow the study of the performance (capacity,
queues, delays, etc) of roundabouts which are divided into two groups: analytical models …

Roundabouts affect operating speeds depending on a number of parameters.
Consequently, their performance affects urban transport systems (safety, environmental and …

In the literature, there are many methodologies that allow the evaluation of roundabout
performances (Capacity, Levels Of Service, etc.): analytical models (HCM, HBS etc.) …

Due to the great increase of congestion levels on transportation infrastructures researchers
and practitioners have focused on the study of safety performance on road network to …

An efficient roundabout is essential in the distribution of traffic to various routes of a traffic
network for smooth flow at its optimum services. The performance of roundabout is a function …

Objective: This study quantified the effect of modifying the intersection angles of Double
Continuous Flow Intersections (DCFI) on their operational characteristics. Mainly, the effects …

En este trabajo de investigación se realizó una comparación de normativa vigente sobre el
diseño de mini-rotondas con países de referencia como España, Estados unidos y …
