Multi-lane Roundabout Capacity Evaluation
Although two-lane roundabouts theoretically exhibit excellent operating performance, in practice, safety problems arise because of inappropriate driving behavior. Turbo roundabouts, which are characterized by a much higher level of safety, are alternatives to classic two-lane roundabouts, but the capacity-related benefits derived from such roundabouts remain an open issue. Accordingly, this stu...
متن کاملModels of Roundabout Lane Capacity
1 Accurate roundabout capacity models are essential for optimal roundabout 2 designs, but there exists significant differences in the predicted capacities of various 3 state-of-the-art models and in their included explanatory variables. An empirical 4 study into roundabout lane entry capacity was thus performed in the U.K. using data 5 from 35 roundabout entry lanes, where various model forms a...
متن کاملAnalysis of roundabout capacity under high demand flows
Estimation of the entry capacity of roundabouts greatly varies between one method and another in their input requirements, model complexity and estimate accuracy. Several available models for the capacity estimation at approach entries of the roundabouts are tested here and compared for high traffic demand condition. The estimated entry capacities along with the actual entry demand are then com...
متن کاملEvaluating Roundabout Capacity, Level of Service and Performance
Results of research on roundabouts in the United States are presented in the NCHRP Report 572. The findings and recommendations of this report are important as they will be the basis of the 2010 Highway Capacity Manual methodology for operational analysis of roundabouts. This paper discusses various findings and recommendations of the NCHRP Report 572 on roundabout capacity and level of service...
متن کاملStatistical Analysis of Two-lane Roundabout Data for Traffic Control Decision-Making in an Urban Area
Researches using existing statistics and data collected from the area of study help officials at decision-making, to improve the region's problems, like the problem of the high rate of accidents in the region, despite the low volume of daily service. The uses of roundabouts in many parts of the world have many advantages over intersections, amongst them are increased safety and capacity and red...
