Street running LRT in Seattle, Portland, and LA manage to survive without crossing bars at all conflict points.
I believe BuildingScout was referring to when a driver parallel to the tracks has a green light, with the tracks on their left side, the driver may attempt to turn left—thereby crossing the tracks. Potentially while a train is coming.
That being said, I would assume trains will proceed and have their OWN green light while both the parallel and perpendicular directions have a red light. That way, no driver will be attempting any turn in the intersection at that point.
