FAQ

Yes, there are already sevral PT references where ITxPT architecture has been implemented and deployed in PT networks. In addition, many PT tenders now include references to ITxPT and related concepts.

Yes, a set IT standards has already been published for PT applications as part of the scope of the CEN group (TC 278 WG3):

• at the back-office level like TRANSMODEL, SIRI and NeTEx
• at the onboard level with the TS13149 part 7/8/9 based on EBSF project results

AVMS services are defined within the ITxPT architecture; not the AVMS system itself (this means the functional description).

In order to achieve integration of an AVMS system with other systems such as DPI, some specific services are required. For instance, ITxPT architecture describes how to subscribe to a DPI application in the on-board IP network to receive stop and journey information from the AVMS.

The way the AVMS locates the stops or the end of each journey (the location function itself) is an internal function of the AVMS as a system and not relevant to the ITxPT architecture.

ITxPT architecture is based on well-known Internet technologies which are commonly used in IT systems.

A Service-Oriented Architecture – SOA – is a modular software design architecture where modules exchange information through services. It is based on publication and subscription mechanisms via a defined protocol. An SOA is independent of any technical solutions and products from suppliers.

By using interoperable services and communication protocols, ITxPT promotes service interaction and exchange of information between equipment from different vendors over shared IP network and service discovery (DNS-SD).

Based on the collection of needs from major stakeholders, travelers, operators and authorities, the ITxPT architecture allows for greater flexibility, easier integration of new technologies, and ultimately, a more efficient and user-friendly public transport system.

Specification updates are announced in the ITxPT website, in the news section and in the ITxPT Documentation Center which hosts the specifications.
The ITxPT newsletter does also share the news, and you can subscribe below. Social networks, such as Twitter and LinkedIn also broadcast such updates.

Three levels of updates can be applied to ITxPT specifications, incremented in their release number vA.B.C:

• Corrective update vA.B.C (e.g. v2.0.1):
  • Applied as soon as an error or bug is reported
  • Frequency: several times a year (if requested)
• Details update vA.B.C (e.g. v2.1.0):
  • Based on input of experiences and feedback from members
  • Frequency: maximum twice a year (if requested)
• Main update vA.B.C (e.g. v2.0.0):
  • Includes key extensions and/or changes of current scope based on workgroups and/or project outcomes
  • Frequency: maximum once a year (if requested)

The ITxPT specifications are published in the Documentation Centre. You can download them in the section entitled ITxPT Technical Specifications.

ITxPT is a non-profit organization open to companies and organizations with an interest in developing public transport into the most efficient, sustainable and attractive means of travel. Its members are a mix of industry, operators and authorities from all over the world. The mission of the ITxPT Association is to enable interoperability between IT systems in Public Transport by offering public specification of an IT architecture based on standards with open interfaces for on-board, over-the-air and back-office IT systems. The ITxPT Statutes comprehensively describe bodies and rules of the Association. More details can be found in the About page.

The process for receiving the ITxPT label requires completion of a few steps.

The ITxPT label is offered as proof of compliance for a vehicle, software or equipment. The ITxPT label can be obtained by any supplier who has passed the compliance tests within the label procedure. It is not necessary to be an ITxPT member to apply for the label, the application form is available in the procedure. The related fees are detailed on this page.

All ITxPT-compliant equipment is listed in the ITxPT catalogue, also available in the ITxPT Documentation Centre. The first module was labeled in 2017 and since then several vehicles and modules have been tested for compliance with ITxPT and have officially received the label.

The first step is to fill in a contact form here. We’ll contact you shortly afterwards to discuss your business needs and expectations from ITxPT membership and help you choose a relevant membership level. We will then send you a membership agreement for you to read and sign, after which you send us back a signed copy. Finally, we’ll ask the ITxPT Executive Board for approval of your candidature. The whole application process usually takes a couple of weeks.

ITxPT is open to all Public Transport stakeholders: Public Transport Authorities (PTA), Public Transport Operators (PTO), Vehicle Manufacturers, IT Suppliers and Consultants.

The ITxPT github resource which can be reached via https://github.com/ITxPT provides examples and validation schemas.
