IMPROVING ROAD CAPACITY

IT IS ALWAYS EXPENSIVE AND OFTEN IMPACTICAL TO ENLARGE A ROAD JUNCTION TO IMPROVE TRAFFIC FLOW. NEW DESIGNS CAN INCREASE THE CAPACITY OF AN INTERSECTION BY AS MUCH AS 50% WITHOUT INCREASING ITS AREA, AS SHOWN BY WORK IN THIS FIELD CARRIED OUT BY THE ROAD RESEARCH LABORATORY IN ENGLAND. MOST OF THE EARLY EXPERIMENTS WERE CARRIED OUT ON CONVENTIONAL FORMS OF INTERSECTIONS SUCH AS PARALLEL-SIDED APPROACHES TO TRAFFIC SIGNALS WITH FAIRLY LONG SIGNAL CYCLES, AND ROUNDABOUTS WITH LARGE STRAIGHT-SIDED CENTRAL ISLANDS. MORE RECENT EXPERIMENTS WERE AIMED AT OBTAINING THE HIGHEST POSSIBLE CAPACITY FROM A GIVEN AREA OF JUNCTION. /BPR/
