Mr. Ciar?n Rogan:

I will mention the two lines by which the system works. Every bus has a vehicle location system which will generate the location of the bus on a map, as against where it is meant to be. That information is then fed into the Dublin Bus and the Transport for Ireland, TFI, apps, the system which runs the street signs. They basically do a prediction as to when the bus will arrive at a given stop. There were software fixes within the AVL system. There have also been software fixes within Dublin Bus, the TFI app and the street signs. Essentially there are three or four separate systems working and dependent upon each other.
