The main point of a stop sign is to control intersections that objectively need the stop to permit safe traffic flow.
We are instead seeing unwarranted stop signs proliferate like rabbits, justified by things they can’t do, like slow or calm traffic.
On top of that, we’re ignoring the problems _caused by_ unwarranted stop signs, including crashes that wouldn’t otherwise happen, increased noise, increased pollution (especially small particles in the stop sign’s vicinity), higher speeds that are induced after the stop sign (drivers make up for time lost at the stop), and the broader consequences of reducing credibility of traffic regulations overall (people aren’t stupid, and when they are conditioned to that stop signs are mostly pointless, the conditioning bleeds over to the whole regime of traffic regulations).
Stop engineering malpractice, ditch most stop signs, and problem solved!
