The problem of minor vehicles crossing or merging into themajor stream at unsignalized priority-controlled intersections iswell-known.Numerous solutions involve various assumptionsconcerning the major headway distributions, number of majorlanes, critical gap distributions, etc.Such cases can be dividedinto two main groups: intersections with two streams (one majorand one minor stream) and intersections with more thantwo streams (more than one major stream and one minorstream).At roundabouts, also at single-lane roundabouts,there are ngetikin.com similar problems like the ones at other unsignalizedpriority-controlled intersections.

A vehicle at the roundaboutapproach can only cross the pedestrian crossing when a sufficienttime-gap between two pedestrians (or cyclists) is provided.A vehicle at the roundabout entries can only merge into the majorstream when a sufficient gap between the two vehicles in themajor stream is provided.Because of that, single-lane roundaboutscan also be treated as read more unsignalized intersections withtwo major lanes: the first one in its circulatory roadway and thesecond one on the pedestrian crossing.
