Capacity evaluation of multi-lane traffic roundabout

摘要: The entry capacity at a traffic roundabout is typically evaluated for each approach, considering the circulating flow and geometric characteristics, e.g., US highway manual model UK Linear Regression model. These models are not appropriate analyzing multi-lane roundabouts because they do take into account possible unequal distribution between lanes. This paper introduces lane-based methodology that evaluates individual lane while on arrival flows formulated based drivers' choice patterns. We then modify extend formulae from existing analysis of roundabout. Based analysis, we show higher can be achieved when utilization lanes more balanced. result lead to improved design management techniques increase
