Wow. I googled him a little more, and his story was fascinating.; > Despite opposition to his concept from many in an engineering profession known for its conservatism, his roundabout designs were formally written into government design manuals in 1975. By this time his experiments had become increasingly radical. Among these were the “magic roundabout” in Swindon in 1972 and multi-ring junction in Hemel Hemp-stead in 1973. > Such junctions comprising as many as six mini-roundabouts — like a series of cogs in a piece of industrial machinery — did cause some chaos when first encountered by bewildered motorists. But Blackmore proved that the multi-roundabouts reduced speed, increased through-put and aided traffic flow. However, the idea was perhaps one step too far for an incredulous engineering profession, and it never really caught on. http://trbroundabouts.com/wp-content/uploads/2015/12/Frank-Blackmore-Times-Obit.pdf http://trbroundabouts.com/wp-content/uploads/2015/12/Frank-B...
