Ethnography: Efficient Parking Lot

My idea for an ethnography is to study parking lot behaviors among the students that park in Lot 50.  After gathering lots of data on the way in which a parking lot fills its spaces I'd like to be able to answer the following questions:

1. Is it more time saving to park at the far end or wait for a spot to open up?
2. If it depends, then when are the best times to wait for a spot and when are the best times to just suck it up and park at the end?
3. What is the average time it takes a really good parking spot to be reoccupied?
4. In what order or pattern are the parking spots taken?
5. How aggressive are drivers when it comes to getting a good parking spot?
