From my perspective, those wooden poles aren't supporting any utilities other than the electricity feeding directly to the stoplights. Should we really call those "utility poles", then? If they were made of metal, I doubt you would even look twice.
I think you might be taking the term "utility pole" a bit too literally.
Edit: What do I call such poles, anyway? What's the term for just the pole itself, regardless of what's attached to it? Merely a "wood pole?" I honestly don't know. I've always called them utility poles, even without utilities on them.
Yeah, I suppose you're right. I hadn't thought this deeply about it when I first posted that, but... Considering that the poles are right there with the utilities, I'm 99% certain they're owned by the electric company, which in and of itself should qualify them for being called "utility poles": they are, after all, poles owned by the utility company. If they were a decent distance away from the electric mainline, then it would be possible they're owned by another entity, but that's not the case here.
As for nomenclature, the term I'm most familiar with is "bump pole", which is an intermediate pole between the mainline and the premise if the distance is too great for a single span. That's not exactly the same as here, but the pole itself would be identical.
