Campus parking seems to be a constant problem at every campus I've been to. I've been trying to come up with a way to increase parking efficiency and become a billionaire from the patents, but so far no luck.
In my case, there is a small parking lot (maybe 50 spaces) near the buildings I frequent, but it tends to get filled up after 10:00, so if you don't get there in time your only option is the metered spots along the roads at a hefty $1.25 per hour. There is one larger lot a bit further that is always full, and a much larger one outside the campus limits that is too far away to be useful. They have a shuttle running from there but that adds a good 15 or 20 minutes to the whole commute.
A bicycle would not be practical for me. It's a short drive but not quite in biking distance (and I don't want to live on the campus as the Princeton graduate dorms are bad even by dorm standards

), and I need to keep a car anyway in order to go anywhere else.
