I would find that to be an unbelievable option. Control systems are just too ubiquitous, and you only have to look at Europe to find examples of far more complex arrangements. Heck, I would suggest that Dutch systems for their car, cycle, and pedestrian network intersections are far more complex than any LRT-involved intersection here in Waterloo Region.
The true problem, IMNSHO, the simplicity and lack of smarts in Waterloo Region's traffic signal system, running on pretty much 1970s-era technologies.
I also find it to be an unbelievable option.
It’s possible the existing intersection control systems are deficient — the only way to interface to the LRT systems may be to go to all-red when so instructed. But that’s just an excuse, not an acceptable explanation. The new intersections don’t need to use the exact same old-fashioned equipment that may be in use at other intersections.
Note that at Northfield the system as installed already behaves differently depending on what rail route is in use — LRT traffic activates the protection system only for the eastbound lanes, whereas freight activates it for all lanes.
