@vitalis yup. I live a quarter mile from what had been a very bad 2 way stopped intersection. It is on the part of suburban Pittsburgh that still transitioning from rural farm land to neighborhoods. A few years back I was nearly t-boned by a full size truck who didn't want to come to a full stop to cross. They put in a traffic circle and the intersection is much safer now.
5 miles down the road, is a two-layer round for traffic congestion management. Not a fan, but it does help.
