What else can you tell us about the "parking deck" other than it has 700 spaces? I'd assume you're talking about one level that has one exit. What happens at or outside the exit is the driving (no pun intended!) concern because traffic will usually back up behind that. Look to queuing theory for an answer - it's probably a lot like information systems!
one time when I parked my car in a lot, some joker decided to box me in. I returned and couldn't get out until the jerk got back and moved his car about an hour later. That was a parking lot problem.
Whenever I go to Gillette stadium they want like $50 to park 1 to 1.5 miles away from the stadium. Boy is that a parking lot problem.
