Quote:What? No, they're not too dumb to do that. They're explicitly designed to be able to do this for transit and emergency vehicles. The trouble is that this functionality isn't used much for transit, for fear of impacting non-transit traffic in any way.
But aren't they one-size-fits-all "you must green in the direction I'm going while I'm coming and then cycle the lights once I'm gone"?
Incidentally, I watched an Ambulance head through Westmount/Erb with preemption live about a week ago. It gave Erb two cycles in a row while I was waiting in the Nbound left turn lane on my bicycle. It is for this and other (green wave, people being in general quite bad at self-transportation) reasons that I believe that the infrastructure's unable to do anything smart.
But, as you so rightly identify, it could very well be that it isn't the intelligence of the infrastructure that's the chokepoint, but the intelligence of those in charge of it...

Are you saying that buses need to stop where light rail crosses an intersection? And is that true? Otherwise, I can't think of a lot more railway crossings.
Do they not? Will they not be
