Makework.
I loath the new signs I've seen. They (A) are not as readable (Helvetica for better or worse has been the standard for all sorts of typography for over 4 decades, there's even a documentary available on DVD through netflix and elsewhere titled simply HELVETICA). And (B), the signs I am seeing are not even reflective. So you can't see them as far down the road.
Re: reading signs, here’s my $0.02...
I was driving through Ojai, CA for the first time last weekend. We got there at night and were trying to find the street that would take us to our destination.
I couldn’t read the street names.
Why?
The signs were a dark, almost redwood color, the names were routered into the wood and appeared to be painted black.
