Full-scale experiments on the Road Research Laboratory track and on public roads have shown simple and economical ways of improving the capacity of, and reducing delays at, single-level junctions of a given size. With any method of control the highest capacity in a given area was achieved with a layout providing the greatest width for each movement particularly at the point of entry into the junction. At 4-way intersections with traffic signals the best results were obtained with non-hooking right turns and cycle times shorter than one minute. With the priority-from-right rule the highest capacity was obtained with a marked deflection of the traffic to the nearside on entry and a very small roundabout central island. The track experiments at 4-way symmetrical intersections with symmetrical traffic demand have shown little difference in the capacity obtainable with the best traffic signals or offside priority arrangements.
