You don't even need that. Just seeing the bus go by "all the time" provides permanence. Really it is better, I've seen plenty of paint/signs/shelters, but when I bothered to look the bus only came rarely. When I moved someplace where I saw buses all the time I realized I could use them even though there was no paint/sign/shelter close to where I got on.
Things like WalkScore show up on real estate listings as a value add.
