The article evaluates the functioning of accumulation areas at intersections with a central island. Three intersections located in Warsaw (Rondo Jazdy Polskiej, Rondo Romana Dmowskiego, and the Toruńska – Łabiszyńska intersection) were selected for the study. These objects were chosen due to the different traffic organization solutions applied to them. To evaluate the functioning of the accumulation areas, two types of measurements were performed.The first measurement concerned the occupancy of individual traffic lanes. The second measurement involved determining the discharge time of the queue of vehicles waiting to turn left. Based on the measurements conducted, conclusions were formulated regarding how the application of different traffic organizations at an intersection affects the utilization of accumulation bays.
PERFORMANCE OF ACCUMULATION AREAS AT INTERSECTIONS WITH THE CENTRAL ISLAND
The paper provides performance evaluation of accumulation areas at intersections with the central island (roundabouts). Three intersections in the city of
Warsaw, Poland, were selected for this evaluation – Rondo Jazdy Polskiej, Rondo Romana
Dmowskiego and the crossroad of Torunska and Labiszynska. These three intersections represent distinct traffic layouts. Two types of measurements were carried out for the evaluation. One type measured usage levels of individual traffic lines within accumulation area. The other type measured time needed to empty accumulation area off the vehicles waiting to make a left turn. The conclusions drawn based on these measurements results show the relationship between intersection traffic layouts and usage of accumulation areas. (…)
