Councillor Saxe with a letter/motion to next week's Infrastructure and Environment Ctte seeking to speed up the SpadinaLRT
From the above:

Fine, as far as it goes.
But the request should have included removing some left turn permissions entirely, removing the u-turn at Nassau and closing that vehicle crossing and consideration for eliminating up to 5 total stops. (2 NB, 3SB )
I agree that removing some left turn movements is key to speeding up the streetcar, but Nassau is not the issue. On the contrary, it's part of the solution.
With phase insertion (as Councillor Saxe is presumably proposing), the U-turn and left-turn phases at minor intersections would have negligible impacts on streetcars since they'd get an inserted streetcar phase to skip ahead of it if necessary. The bigger issue is at the major intersections (King, Queen, Dundas, College) where it takes 30+ seconds for the streetcar to cross the intersection due to the track switches. Inserting a 30-second streetcar phase into a 90-second cycle would decimate the intersection's capacity and create lots of delays for east-west streetcar lines. A better solution for those intersections is to eliminate left turns entirely, with drivers redirected elsewhere.
For example, we could eliminate north-south left turns at Spadina & College by redirecting northbound left-turning drivers to loop around Spadina Crescent, and southbound left-turning drivers doing a U-turn at Nassau.
If you really want to do this right, have the signal system allow a streetcar-only movement phase both before the left-turn phase for cars, but also add a second one for streetcars after the end of the green signal phase for cars going north/south on Spadina, so there would be two opportunities for streetcars to move through the intersection on each cycle, one at the beginning and one at the end.
Yes I assume the motion is talking about inserting streetcar phases, not just changing the default order. Simply changing the order of the phases would make no difference to streetcar delay.
For the opportunity at the end of the north-south phase you don't need a separate phase, since streetcars already get a green during the north-south phase anyway. You just need to extend that phase if there's a streetcar approaching, which is already what the signals do at minor intersections along Spadina.
