This work proposes a new method to quantify the coupling in hybrid design matrices for traffic intersections by
taking into account the presence of coupling, the types of conflict that coupling may introduce, and the impact that the conflict may have on the intersection. The result is a single numerical value, called the coupling impact index, which can be used to select the safest intersection design for a given situation. This technique is demonstrated with a case study which calculates the coupling impact index for three traffic intersections based on two sets of traffic conditions and suggests the best intersection for the anticipated traffic volumes provided.
