Of course it would help, since an overloaded intersection causes a large backlog and waiting in line (for multiple light changes) is how each vehicle pays the cost of the backlog.
With dedicated bus lanes, you skip the backlog and cross on the next light, so intersections do not undo the advantage of dedicated lanes.
You don't have to take my word for it - just ride any good dedicated lane system at a high traffic time and note your relatve speed of progression versus car traffic.
- bryanlarsen 8y agoI ride a dedicated BRT lane system every day. Part of the way they have overpasses and it's super fast. Then they hit downtown and have dedicated lanes but have to deal with normal intersections. It's dog slow.
- BeeOnRope 8y agoIt's all relative. Do you mean it is slow compared to the portion with no overpasses, or slow compared to vehicles w/o dedicated lanes passing through the same intersections? Passing through intersections is never particularly fast (except perhaps at night on empty reads with sensors far enough away to turn the light green before you even get there) - but at peak times dedicated lanes help a lot even when intersections are involved because you skip the queue.
- bryanlarsen 8y agoIt's slower than the car lanes; there are so many buses that the bus lane is more backed up than the car lanes. They are in the process of building a subway that'll take many of those buses out of downtown, though. (Ottawa, Canada).
- BeeOnRope 8y agoYes - a single dedicated bus lane doesn't work if there are so many buses that lane is busier than the car lanes! That would be a fairly unusual case in my experience though.
