Don't confuse traffic studies with facts. Adjust a variable here and there and numbers can change significantly. Where was the counter set? West of the Richmond & Jarvis ramps where the number is lowest? When ever you look at a study, you also need to look at the agenda behind those who did or commissioned it, and there certainly is a "remove the Gardiner" agenda at the City.
Studies also need to be viewed in a broader context. The "remove option takes all the am peak direction traffic on the DVP south of Bloor and directs it to lights at Lake Shore, or (combined with traffic from Lake Shore to the east) to lights on the new "boulevard" east of Cherry Street. The Richmond ramp is gone, so traffic from the north (DVP) and east need to find new ways to filter up into the core. The Adelaide ramp is also gone, so good luck leaving the core towards the north & east in the pm peak. 3 lanes of am peak traffic from the west are now going to end at a light at Jarvis. It appears that the City has not learned from the Allen Expressway experience, and wants to create a super version of it 2 more times at the core of the City. Doesn't the definition of insanity say something about doing the same thing over and over again and expecting a different result?
And don't count on transit to improve the situation. The MetroLinx proposal doesn't even keep up with projected growth and results in slightly increased commute times, even if everything is implemented. And Tory's Smart Track hasn't been through that level of analysis.
The Urban Design arguments don't fly either. An 8-lane fully congested road with 3 signalized intersections isn't easier to cross to connect the City to its waterfront than going under the elevated hybrid option. Nor does it create a more desirable street environment.
