Did anyone study the fuel efficiency of a roundabout vs. traffic light?
I expect it to be a lot worse.
- roundabout, light traffic : break, turn, accelerate again, 100% of the time
- (dumb) traffic light, light traffic: 50% chance of stopping and accelerating again, 50% chance of not slowing down at all.
- roundabout, heavy traffic : stop, move 3m, stop again, move 3m more, stop again, repeat 10 times, finally turn, accelerate.
- traffic light, heavy traffic: stop & engine off, start & move 100m, stop & engine off, start again and accelerate.
You're missing the variations where you have stop lights to go into the roundabout or the even worse variant, roundabouts that are large enough to have 3-4 zones of stoplights inside of the roundabout itself!
I'll take a roundabout any time of the day, but then I mostly to drive out in the public when the traffic is the least, so any stop lights tend to be more annoying that useful.
