You can't really tell because of the angle and field of view if there is a traffic light/sign there or not. The various numbers on screen mean something, but I don't know what. But, watching the video, it would appear that the cross traffic was stopped. Notice that it is several seconds after the collision that you begin to see cross traffic moving through in both directions. In fact, the traffic in the far lanes (top of screen) is grouped as it would be just starting out from a green light.
So, it looks to me like the woman driving the car ran a red light. That would certainly explain why the biker was so irate, and he doesn't appear to be drunk, only dazed.
What amazes me is that he hoped right up, almost as if nothing happened and yet his bike is trashed. Wow. He's damned lucky regardless of who was at fault.
