From standard to passenger experience:
ITxPT as the engine of real-time information

With ITxPT we get a common language for how buses and backoffice systems exchange data, for example about position, timetable and operational events. The standard’s services – such as position (GNSS) and AVMS functions – define how real-time data should look, so that other systems can understand and use them without custom work.

If we boil it down to something very concrete, the chain typically looks like this:

• 1. The bus sends its position using standardised messages.
• 2. The AVMS layer combines the position with the timetable and calculates expected arrival time and any delays.
• 3. The passenger information system subscribes to this data and uses it to show next stop, real-time departures, transfers and service messages on screens, signs and in apps.

Because the interfaces are standardised, systems from different suppliers can work together on the same journey. One system provides the position, another does the calculations, a third shows the information to the passenger. ITxPT ensures that they understand each other without having to start from scratch every time.
 

Adibus RealTime – ITxPT at passenger level

Adibus builds on this architecture with adibus RealTime, which handles the entire chain from timetable to screen. The driver selects the trip on the driver display, the system retrieves the relevant data for the route – and from there everything runs automatically with next stop, terminal, delays and transfers.
 

The same data can be reused in multiple places:

• Inside the bus: screens and audio announcements for next stop, connections, campaigns and traffic messages.
• Outside the bus: apps and websites with expected arrival times, based on GPS, timetable and historical data.

Here ITxPT makes it possible to connect Adibus solutions to other systems – for example national data hubs, third-party apps or regional screen solutions – without having to create new proprietary integrations each time.
 

The benefits for PTAs and PTOs

For a PTA or PTO the focus is not on the technical details, but on operations and passenger experience. An ITxPT-based real-time solution provides:

• more precise and consistent real-time information, because several systems can share the same data,
• less vendor lock-in, because components can be replaced without breaking the whole chain,
• better reuse of investments when new buses or new contracts are added.

Adibus’ role is to deliver a real-time platform that already speaks ITxPT – and at the same time translate it into something very tangible: screens, signs, apps and reports that create confidence for both passengers and operations.
