Is there an existing European Standards for IT architecture?

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

What is a Service-Oriented Architecture?

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.

Vehicle location, voice call or vehicle delay/advance estimates are typical AVMS functions, why are they not described as AVMS services in the ITxPT architecture?

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 […]

What is ITxPT architecture?

The EBSF project defined a set of needs of major stakeholders, travellers, operators and authorities for innovative bus systems in urban and suburban areas using new technologies for vehicles and infrastructure. ITxPT architecture describes a set of services and the way these services interact or exchange information using an IP network in order to satisfy these needs. The services are described by focusing on key PT applications like Advanced Vehicle Monitoring System, Dynamic Passenger Information and Remote Diagnosis, defining services such as: Vehicle Gateway Automatic […]
