They’re often worse in heavy traffic situations. Especially if you have two entrances that feed heavy traffic into the roundabout at peak times, the one that has to yield can end up basically locked out of the flow.
- hnick 3y agoYes traffic lights can be far better in heavy traffic - at least everyone gets a turn. In some roundabouts I've driven through, where there is a "main" way the cars coming from the other directions often get locked out as people queue through it. It works out if people have some courtesy and take turns but that's not always a good basis for traffic planning.
- Maxion 3y agoIf the heavy traffic or the locked out traffic does a right turn in the roundabout, then a solution to this is a bypass lane. This works very well for letting traffic through and opening up the roundabout. Multi-lane roundabouts help when theres a clog downstream of the roundabout. Roundabouts are also great if you have more than 4 roads meeting. But yeah, in general roundabouts shine the most in low-traffic intersections that previously had lights. They make driving in those are so much nicer, drivers basically never have to stop.
