Absolutely! Traffic calming can play a role. In fact I have been working with the County on traffic calming here. But their process is silly: paper ballots sent to homeowner’s (but not apartment renters!) along the road and a 67% turnout is required for a vote to pass.
We worked hard canvassing and educating and “only” got a 52% turnout and a 100% yes vote for traffic calming. So the vote failed.
I wrote a 10 page report on all of the ballot design failings, administrative issues, equity issues, etc and they are reforming the program and introducing digital ballots. Still working on that 67% requirement though (a recent 9 figure school bond passed with a 37% turnout).
As someone involved in election systems to some degree it was eye opening seeing something so poorly designed and executed.
That said traffic calming isn’t necessary if the roads are designed to prioritize pedestrians from the beginning. It is a patch to a bad design- or at least a design that prioritizes the wrong thing.
