I think the main difference is the Vix system uses the vehicles running board rather than trip numbers alone, so an example is if a bus is running 10 minutes late into a terminus and it is changing route/trip number, and the running board says he has 10 mins layover, the system will then say he is going to depart on time, however if running 12 late, it will say he is departing 2L.

I think the Arriva system just looks at trip numbers only, so until a driver keys in a new journey number, it assumes the vehicle is on time. And of course you should never assume as it makes an ass out of u and me

The Arriva system does work on the bus board, so it should provide delay information for subsequent journeys when using the planner - even if the trip hasn't commenced yet, but the bus that is due to operate it is somewhere near to completing the trip before hand.

Not sure if it calculates delay with layover offset though.
