Crested Newt, we had a similar problem with double glazed windows. If you look at them from certain angles the landscape is reflected and birds think they can fly straight through them. After some bird tragedies usually early in the morning, all the windows now have small stickers on them placed about two thirds of the way up to break up the reflection. It really works.
What you could do is get some stickers that can't be easily removed and go out to the bus shelters in your area and stick them on, or ask the council to do the same.
