hybrid1. I am not quite sure where your getting your quote from. I read the AA, and I did not find what you quoted here. Chapter and Verse please on that one. 
Second, let me give you a real quote from the AA to counter your point, because I am not sure if anyone in the critics corner has really read the findings of the AA. Page 3-22 in the AA states that a no build (rail system) alternative predicted to see a worsening of the traffic in the Kalaueo Stream and Kalalama Canal area of H1, with peak-hour volumes increasing from 25 to 48% at Kalaueo Stream and 11 to 21% at Kapālama Canal. 
Now the AA was written in 2006, a full 11 years ago and what do we see now? Well, volume as greatly increased if you are ever a participant on the freeways in that area at peak rush hour times during the school year. There are other predictions in the AA that are coming true now, which was why the AA stated the preferred choice was what we are building now.
