The Determination of Conflicting Flow Rates for the Calculation of Capacities of Minor Traffic Streams on Priority Intersections

AbstractThe calculation of potential capacities of minor traffic streams on priority intersections requires the determination of the conflicting flow rates. The article describes a procedure that allows a more precise determination of conflicting flow rates for rank 3 (e.g. through traffic on minor street) and rank 4 (left turn from minor street on four-leg intersections) traffic streams compared to existing approaches. The procedure is based on an in-depth analysis of interactions between traffic streams and was developed using simulations and regression analyses. © 2011 Published by Elsevier Ltd
