Let's Go Vertical

Idle Aire went bankrupt. So did Park and View (before your time, but you might still see a yellow hub in a parking lot occasionally). truckers are cheap, and so are the BFI's. The rigs climbing the ramps and reefers would be the main noise issue, as obviously an enclosed area like a parking garage would be a no idle zone. The structure would be a huge expense, especially in the areas they are needed, as in 10's of millions of dollars, so there is no way you'd be paying $10 to park. As far as the eyesore, apparently you've never dealt with the NIMBY folks. It's a good idea, just not practical or economically feasible.

 

What did you have in mind as far as the trucks accessing levels 2-(whatever)?
A curved incline would probably be wrecked by split axle trailers and people who don't swing wide enough.
A ramp would need to include enough room for trucks going up and down and room to turn in either direction without hitting anything, including overhead clearance.

 

The best scenario, if you HAD to have a garage for some reason, is the automated type you see in some cities, where you park your vehicle on a skid and hydraulic lifts put it in a slot similar to a forklift and pallet racking. I don't see any reason it wouldn't scale up to rigs, but it would be expensive. Face it though, Europe and British are far tighter on space, and they don't have them. I do believe the answer to the space problems will be regional drivers returning to their hub at most every other night. This is how it works for a lot of the northeastern carriers.
