Specifically, I-84 mileposts 0 to 7 (roughly I-5 to I-205) are very congested. MP 7 to MP 17 (I-205 to Troutdale) is somewhat congested but not nearly as bad as west.
MP 17 to MP 378 (Snake River, Idaho Border) is a very, very empty stretch of road. Just driving from MP 16 to MP 19 you can see a huge difference as a huge chunk of traffic takes the Troutdale exit (the last exit before leaving the metro area).
Here it is in data from ODOT:
MP 0.49: 143,200 average vehicles
MP 1.43: 171,700 (this is the highest volume of any highway in Oregon)
MP 5.31: 145,200 (west of 82nd Avenue)
MP 6.75: 47,100 (this is within the I-205 interchange, for vehicles continuing on I-84)
MP 9.78: 110,300 (east of I-205)
MP 13.44: 82,600 (in Gresham)
MP 16.46: 47,000 (in Wood Village, west of Troutdale exit)
MP 17.71: 29,100 (within the Troutdale interchange, for vehicles continuing on I-84)
MP 22.4: 24,900 (Corbett)
MP 43.58: 20,000 (Cascade Locks)
MP 64.24: 28,800 (Hood River)
MP 85.27: 21,600 (The Dalles)
MP 104.86: 11,500 (Biggs, U.S. 97)
MP 146.16: 10,600 (Arlington)
MP 167.18: 16,100 (Irrigon, U.S. 730)
MP 180.05: 13,000 (east of I-82)
MP 203.34: 15,200 (Pendleton)
MP 262.34: 9,100 (La Grande)
MP 303.74: 9,600 (Baker City)
MP 376.98: 16,400 (Snake River/Idaho Border/Ontario)
Add to that, Greyhound has reduced frequencies on this route; Horizon Air has eliminated Pendleton service and no longer serves the Tri-Cities to Portland route (Tri-Cities is served to Sea-Tac) - essentially there is a lot of point-to-point Portland-Boise traffic that would not be effectively served by rail (judging from Horizon and Southwest flying the route) but hardly any significant traffic along the route. Much of the traffic on I-84 is truck traffic - in some places 50% (very high!) and much of the traffic is also "local" (i.e. Arlington to The Dalles).
I believe a two-lane road is considered "at capacity" at around 26,000 vehicles, and I-84 is four-lanes the entire way from Troutdale to Ontario. ODOT could decommission half the freeway and still have excess capacity...
Bottom line: Oregon could spend the money much better on a Portland-Salem commuter rail route and would have 100x the ridership than the Pioneer out to Boise.
As for the Seattle-Portland-Boise-Salt Lake-Las Vegas-Los Angeles route: Again, ridership is very sparse. Few would ride the route end-to-end but presumably this route wouldn't be intended for such but rather a combination of multiple segments attached together (which isn't a bad idea, there are a lot of good segments - the problem is that the distance between the ridership generators is huge - six, seven, eight hours apart - too much for "coach" but too little for "sleeper".) Essentially the only real competition is going to be Greyhound, because those people are already willing to sit in a bus for that long. And for the LD market - is the scenery there to really sell this train? Outside the Columbia Gorge (already served by the Empire Builder/Portland Section) and maybe Durkee Loop/Strawberry Hill...there isn't much to sell.
