I don't have a picture of it yet, but the old railroad that used to follow Canoga Avenue in the S.F. Valley has just recently been reborn as a dedicated busway. Anyway, because it's so close to Canoga, the Busway's traffic signals also work in tandem with Canoga's signals, so they are actually positioned before one crosses Canoga. (Although it should be noted an identical set of traffic lights is still traditionally past the intersection.)
The only time the two wouldn't be synchronized is when a bus is coming, the operator has a special transponder.
