These signs are in NW Arkansas. The Norman Chamber of Commerce and the city were working on wayfinding signage here, but so far, the only thing that has happened is a few MUTCD-standard signs near the interstate. An improvement to be sure, but something that should have been installed when the highway was built!
This is pretty neat. Here, the guerrillas are tired of waiting for the city to honor their request for slow zones.
I get why the people in cars think this won’t work but there are solid observational results that say it will. In Calgary, even.
This is definitely a case where a trial could be done, either with paint or with those flexible posts or even Jersey barriers. If it doesn’t work after a reasonable trial period (like 6 months or a year), then you take it out and you haven’t spent a lot.
