intersections of multi-use paths don’t have stop signs and don’t need them.
We have a few municipalities around here that are adding stop lights for cyclists where multiuse paths meet intersections (to control the cross rides).
It’s more of a safety thing, but I’ve almost been run over several times while crossing them on a WALK/BIKE green, since motorists really don’t care at all.
You will often get a motorist committing to a left turn going into the cross ride, and since they didn’t look first and didn’t give themselves any time before the oncoming traffic arrives, they’ll plow through the cross ride/cross-walk. To say that I see this happening all the time is not an exaggeration.
