At the 27th Annual International Council on Systems Engineering (INCOSE) Symposium in 2017, staff from Asset Standards Authority (ASA) presented the Transport for NSW (TfNSW) Transport Network Architecture (TNA) model. The purpose of the model is to provide a common understanding of goals, capabilities and concept activities to ensure effective engagement by key stakeholders.

As a part of the exploratory and scoping phase of the TNA Model project, ASA engaged University of Wollongong’s SMART Infrastructure Facility from 2013-2015 to conduct initial investigation into systems modelling language. SMART is an international leader in applied infrastructure research, bringing together experts from fields such as transport, water, energy, economics and modelling and simulation within a state-of-the-art facility to support this important package of work.

The TNA model is a system architecture that integrates multiple strategic documents into a structured, visual, relational format that can be used consistently across the Transport cluster and supply chain. This conceptual model captures information in order to represent the structure and behaviour of the transport system. It aims to provide a basis for consistent asset planning and procurement for complex transport projects. The different perspectives and views in the model allow a particular user to define and bridge the link between the business needs and requirements (i.e. problem domain) and the system needs (i.e. solution domain).
