Yeah, that's how I understand it too, all the lights behave more or less independently when it comes to priority. I'm not sure how that works in a green wave situation. I also assume that an emergency vehicle can come along and throw everything out of whack.
I was doing a bit of googling about this, and I found a release from 2011 (http://www.regionofwaterloo.ca/en/region...1-0906.pdf). It says:
So maybe it is a bit more than just extending green lights and shortening reds.
I also wonder if this is needed as part of the solution to the UW transit plaza. Will the buses use the systems to open the gates to cross the tracks? From the article:

Quote:The functional capabilities needed for the upgraded TSP software module have been identified by staff and include some features and event logs such as: queue jump operation, ability to skip phases, multiple user-definable features, multiple input capabilities, logging of TSP adjustments to the signal timing and future vehicle tracking.

Quote:The devices allow a bus running behind schedule in key areas to shorten red lights or extend green lights at intersections, activate transit-only signals at intersections with transit queue jump lanes, and to control gate systems at transit garages and other locations.
