I will add though for Vancouver, that the bus stop example at the top is more common of transit exchanges. I include it because I much prefer signs that have bus destinations on them too, not just the number. On the street, this is the model that is being phased in right now:

So speaking of branding, the orange background is for "B-Line" buses, which is the branding for limited-stop, high-frequency service. White is regular bus service, and dark blue is for night buses, that largely run radially from downtown between 2-5 am.
