No, PXOs are not integrated, which is why the city can install them, even when regional engineers disagree.
What I meant is that pedestrian signals are integrated into the system. We could not install one separate from the region's system.
But that’s my point. I don’t see why a pedestrian signal has to be integrated. If it’s OK for a non-integrated PXO to stop traffic without regard for the state of the main traffic signal system, it’s OK for a non-integrated pedestrian signal to stop traffic without regard for the state of the main traffic signal system. Either way, traffic is stopped on demand whenever somebody on the trail pushes a button.
Because a PXO is not a programmable system. It's just a flashing light. A traffic signal, even one for peds, is much more complex, it has programmable timings, it can be synchronized with other signals, it responds to fire vehicle signalling devices, and could respond to transit vehicles, and these features can be controlled centrally.
Yes, Kitchener could technically buy and install all this equipment but it would cost millions of dollars, and that's assuming it's even legal for us to do so within the existing confines of our governmental system.
