Quadrant intersections ease congestion at four-approach intersections, specifically those with either heavy through movements or heavy left-turn movements. One (single-quadrant) or all (multiple-quadrant) left-turn movements are guided to connector roads, shifting these movements away from the main intersection. This arrangement provides enough green time to the movement with the highest traffic volume.
