Making data available to relevant stakeholders creates opportunities for coordination and holistic planning processes but to truly understand and leverage the data, modelling methodologies and tools can be used. Computational modelling is the use of computers to simulate and study the behaviour of complex systems using mathematics, physics and computer science65. Data on national infrastructure can be leveraged to build computational models for a deeper understanding of the properties of the system as a whole and the effects of factors such as demand and supply, demographic changes, and climate change.
