In the last few years, VAB has implemented a number of innovative ITCS systems for bus and rail companies. Users are particularly impressed by the modular concept of the multi-client capable system, the excellent user-friendliness and the cost-effectiveness of the system. One special feature is the integration capacity for different makes of mobile and stationary bus printers, on-board computers and smartphones as vehicle terminals. This enables parallel operation of different end devices, for example smartphones and bus printers, as well as the integration of additional vehicle fleets into an existing VABnet ITCS.
