The building right across from it is wardrobe, aka, the main team member entrance. And that road that goes off besides the wardrobe building goes to/from the main vehicle gate for backstage access, so pretty much constant traffic around there. Just a few buildings down is the main cafeteria.
So, arriving workers - shuttle busses for workers - and upper level staff, plus internal vehicles zipping around. A small number get to drive around backstage in a personal vehicle - most are driving the company fleet, but there's a decent number in the company fleet. The road is always busy.
It's also one of the few parking lots anywhere near the cafeteria.
