ITxPT Specifications

The ITxPT specifications are publicly available and free to use by anyone. They provide public transport authorities and operators with recommendations and requirements to support the purchase and integration of interoperable IT architecture. What is more, industry suppliers use the specifications to design ITxPT-compliant equipment and services.

ITxPT architecture is based on standards and best practices from in-operation implementations and projects like EBSF_2. The ITxPT specifications do not limit the design of IT. They just provide a framework for how to design hardware and software so that modules can be integrated in a coherent architecture. This simplifies IT suppliers’ access to the market and gives purchasers the flexibility to select services and components from many different providers. ITxPT should be understood as an agreement between many public transport stakeholders to enable digitalization and integration of mobility services.

ITxPT defines interoperability on 3 levels:

Hardware level:
installation rules, space requirements, connectors, etc.

Communication protocol level:
interfaces, declaration of service, etc.

Service level:
list of services, format of the service, format of data etc.

ITxPT benefits from standards and open-source protocols such as:

  • TS13149
  • DNS-SD
  • mDNS
  • Transmodel
  • NeTEx (Network Timetable exchange)
  • SIRI (Service Interface for Real-time Information)
  • OJP (Open Journey Planning)
  • TiGR (Telediagnostic for Intelligent Garage in Real-time)
  • MQTT bridge OTA

Compliance with standards and standardized interfaces are necessary for service providers to be able to share data. In the rapidly developing transportation industry, this is becoming increasingly important.

The scope of ITxPT is continuously developed by the association and at present the following services are included:

  • 1. Module Inventory
  • 2. Time service
  • 3. GNSS Location
  • 4. FMStoIP
  • 5. VEHICLEtoIP
  • 6. AVMS
  • 7. APC
  • 8. MADT
  • 9. MQTT Broker
