Sure. I think we will see RFID readers installed into the bus stop areas so they can ping the MBs of the guest waiting there. They can tell which stops have how many people in them, how long those people have been there, and can also make an educated guess on why they are waiting for the bus (going back to the resort they are staying at vs trying to make an ADR that is linked to the same
MDE account as the MB).
They can integrate that data into the existing bus dispatch software (MIMs per a PP who seems to know) to better route buses based on real time demand.
I think the cast members might have either had an RFID reader on them to collect data or were manually doing some of the routing they are going to eventually automate down the road. The screens being installed with wait times only really makes sense if you have accurate numbers to put on those signs and more advanced routing based on real time metrics would lead to that.
All of this is an educated guess and I could be way off.
