Why not just install a roundabout?
A roundabout does not protect people riding bicycles. This intersection is designed to make them more visible to drivers.
Can you draw that? How does it work when a bicycle wants to go straight and a car wants to turn right? Either you would need underpasses/overpasses or accept that cars and bikes will constantly cross each other, which in practice means the bikes will be in danger.
They put in protected bike lanes on big street near me. Bike lane-parking-traffic. So many ‘bike allies ‘ saying “it makes me more nervous to drive, I have to look for the cyclists now”.
In a large part of the US at least, it’s never going to be default behavior.
It makes me nervous as a cyclist, too. I think I'm safer taking the lane and navigating like a car than crossing a car's path from a segregated right of way.
You're assuming that most people are decent law abiding drivers and won't be impatient and simply use that as another lane or parking spot.
Not if "protected" means "separated by a barrier".
I'm interested in your design of a roundabout with a protected bike lane. Does it have over passes or underpasses?
Detect when a biker is approaching, let spikes spring up.
Wanna bet? 😂
You could still put an obstruction in the middle to prevent t-bone collisions while keeping the bike and pedestrian spaces.
Because roundabouts prioritize motorists, their safety, and convenience. Clearly the goal here is to improve pedestrian and cyclist survival and convenience.
Do you any data supporting this ? I really wonder what would be best for cyclists.
Seems the opposite to me. I see in this picture what is essentially a roundabout but missing the central island, meaning people can drive straight through.
Roundabouts force motorists to slow down and can still provide a safe perimeter around the edge for pedestrians and bicyclists.
Have you crossed a roundabout by foot? The crosswalk is offset from the border of the road by like 5 meters, meaning it takes like twice as much to cross. The crosswalk is also not in the slowest part of the roundabout.
This intersection forces drivers to slow down by having floating islands that narrow the lanes and force tighter turning radii. Drivers going straight through interact with pedestrians and cyclists less than drivers who are turning because this is a signaled intersection.
Roundabouts need more space than a regular crossing and there are buildings on all four corners here.
That's what mini roundabouts are for.
Imagine if they had to drive in the UK lol
...at Bloor and St George? People walk here
