While in college and the University of Texas in Austin I had job counting people getting on and off the city busses and UT shuttles.
Ask the driver, they will know.
Hah :D, drivers always know but some of 'em are lazy!
People inside might have RFID / NFC technology with them, like badges, but we can't count on them 100% as someone might forget or not have that piece at all.
Of course, buses will slow down when they come to a "checkpoint" to allow devices (cameras) to perform better scanning.
By the way, it's a civil project, nothing to do with law enforcement. A huge convention center wants to know in advance, if 100 buses are coming, what number of participants to expect at their gate.
