I have a question:
How will the Eglinton Crosstown affect traffic/ traffic lights at the at grade sections in the east? Will they be raised or tunneled at intersections such as Leslie, Don Mills, VP, Pharmacy, Warden, etc?
In theory, they will have "transit priority".
However, I think that it'll mean single-occupant vehicles making left turns will still get priority, followed by everyone going straight. They may delay the green light for everyone going straight, if there is a LRV train coming or crossing the intersection, but that's it.
The traffic signal lights are the responsibility of the roads department. For them, it means any vehicle are their outmost obligation, no matter how many actual people are inside. So even if one Flexity Freedom car carries 250 people (and a train of three cars carries 750 people), they are still count as only one vehicle to the roads department. So the three single-occupant cars making a left turn have a higher priority for them than a LRV of 250, because there are more vehicles.
The roads department could have experimented with setting up a proper transit priority system on The Queensway, but no. Instead, they forced the streetcars to go slow (7 km/h) at the intersections, wait for cars making left turns, and wait with the other motor vehicles. The "go slow" signs have been removed, but they still have not set up a real transit priority, unless they delayed the green signal. However, it doesn't look like they did.
I hope that by the time the Eglinton Crosstown LRT and the other LRT routes open, that there will be real transit priority.
