If I had challenge I'd try two things on different weeks.
Commercial parking lots like what is used for smaller stripmalls yhay have bigger corporate tenants like a big drugstore hire parking lot maintenance companies. The guys cleaning use a large rolling vacuum. It can pick up teeny bits of glass. Hire him. Probably 40 bucks.
Coat the entire track with sugar water early in the morning.
