This week, there was a new change. The security officer on the bus checks identification before allowing you to board the bus. This is an entirely new practice. Then, as it was before, when you get off the bus at campus, your id gets checked to make sure you have a bus pass (students) or are otherwise authorized to ride (staff or faculty). Then there is another id check for getting onto campus, which includes putting your bag through an airport-style x-ray machine and walking through a metal detector (which I don’t think is too sensitive or serious as I have never emptied my pockets).
