As you've likely heard by now, they've implemented the King Street Transit Pilot between Bathurst Street and Jarvis Street. Rules are in place to prioritize streetcar traffic and to prevent private vehicles from driving through this stretch of King.
I don't currently drive on King Street, nor do I take the streetcar there, but this is what I know. King Street is the busiest surface transit route in the city, moving more than 65,000 riders on an average weekday. The tweets I've seen from some of these 65,000 riders has been overwhelmingly positive. Commute times have been dramatically reduced and streetcars are just cruising.
The 20,000 vehicles who use King Street each day have and will find alternate routes. Perhaps some of these drivers will leave the car at home and take the streetcar now that it's faster, less crowded and better spaced. Common sense suggests it's far easier to move the 20,000 vehicles than the 65,000 people on streetcars.
If you used to drive KIng Street along this stretch, I'd love to hear from you in the comments. And if you're one of the 65,000 who ride a King streetcar, please let me know how things have improved.
From where I sit, this looks like it will be a tremendous success.
