Dunno...rather than 'Hooking it and using Google to talk wisely about something I absolutely nothing whatsoever about I can only go on what I see.
I take my lady to the train station every morning where she commutes into the city, all the way to Westlake Center where her office is.
Sometimes the train goes right by because it is too full to stop...other times "not full" trains go by so that folks on the following stations have the chance to get on a train.
The train goes by every 7 minutes and by the time it gets to the downtown stations...of which there are many, which is not "none", by far...they are all completely full.
The station I drop her off at has 700 spots, and they have opened up another lot up the street for overflow that has another 200...all 900 of those spots are full every single workday morning by 7am. Lots of folks park on the surface streets around the stations so they can take the train.
Opening up a new lot a few more miles south on the line will more than double the amount of parking spots for commuters to use.
It's not just that way during peak work day times...81 days per year it happens again for every single home Mariner game...and for every single home Seahawk game.
To a lesser extent it happens for Husky games, but plenty of folks take the train into the city and then take the bus from downtown out to UW.
I have taken the train into the city maybe eight or ten times...never during peak work times, a couple of times around lunch time, and the rest in the evenings for Mariner games and whatnot...and the train has been full or almost full every time by the time it gets downtown.
I usually end up standing so that someone else can have the seat I've been in for the first half of the ride.
I have no idea how much that reduces pressure on congestion or parking downtown, but I know for sure that it is a positive for both.
If you are actually...actually, not just partisan hackery talking point actually, but really actually...concerned about congestion then something that is proven to work...the light rail system...should obviously be expanded, and it should be expanded a LOT.
If you "see" 2 or 3 people on the trains then you are either blind, or making it up. I suspect the answer is "making it up", though a quick visit to your eye doctor would let you know for sure which one it is
Fish on...
