Why TNA model? • Enable innovative solutions • Requirement traceability to long term goals • Improve quality of requirements • Encourage use of model-based approach www.incose.org/symp2017 6
The Transport Network Architecture How is it developed? • Adopt a Model-Based Engineering approach • Adopt ‘TRAK’ Metamodel as Framework • Adopt UML and SysML as Modelling Language • Acquire stakeholder input • Use a system architecture tool www.incose.org/symp2017 7

The Transport Network Requirements Why develop it? www.incose.org/symp2017 10
The Transport Network Requirements How is it developed? • Validate functional model • Establish and develop requirement viewpoints www.incose.org/symp2017 11
Where are we now? TNA Model v1.0 TNA Document v2.0 www.incose.org/symp2017 12
Future Direction • Use the model on transport projects • Use case development • Extend TNA model to other modes • Develop transport network requirements www.incose.org/symp2017 13
