Uh, you don't
reduce traffic by
adding traffic. That's tar sands logic. Best case is that you prolong the inevitable by ~20 years, at which point induced demand catches up and you're back to square one.
More to the point,
TransLink pre-lockdown saw about 740k boardings a day; that's anywhere from 124-370k Origins (depending on passenger load). Best of luck trying to fit all those new cars on the road AND lower congestion.
