>>1100945>>1100942>because the mergeon/mergeoff lane is the same lane and its so short causing backups and accidentsAnother serous problems. Cloverleaf FIRST ADS traffic to road, and only then it takes out traffic of cars merging out to leaf for left turn. Obvious problem if you start add traffic to road working near maximum capacity you are creating conditions for traffic jam. Even worse, cars need to merge out through this jams. Very bad.
Turbine interchange on the other hand first takes out traffic of cars which want right or left turn and only after adds traffic into road, onto right now empty lane.
