RoundaboutPhase diagramDensity profilesUsing the cellular automata model, we numerically study the traffic dynamic in a single lane roundabout system of four entry/exit points. The boundaries are controlled by the injecting rates α 1 , α 2 and the extracting rate β. Both the system with and ...

1 Single-lane roundabouts are modeled with installation of pedestrian scramble crossings to allow 2 heavy volumes of pedestrians to walk across the legs and through the center. VISSIM microsimulation 3 considers experimental origin-destination (O-D) balanced flow scenarios (total traffic flow into and...
Finally, we have investigated the effect of the braking probability P on the interior lane of the roundabout. We have found that the increase of P raises the spontaneous jam formation on the ring. Thus, enlarges the maximum current and the jamming phase while the free flow phase decreases....
In this paper, we examine the impact of vehicles executing a full turn or U-turn in a single-lane roundabout system using a cellular automaton model. We investigate how increasing the number of these U-turning vehicles affects traffic flow characteristics and energy dissipation. Our findings ...
Roundabout planners and designers are often faced with situations where a multi-laneroundabout will be required to handle the design-year traffic volumes, but where a single-laneroundabout would be sufficient for a number of years. Due to issues of safety, complexity,driver familiarity, and ...
Case study is placed in Zilina, the city on the north of Slovakia, where the single lane roundabout has a great congestion problem not just during peak hours. Configurations of the roundabout are evaluated and compared from their performance parameters using microsimulations and theoretical models. ...
