Liveable city digital twin
Analytics for Agile decision making
Analytics for Agile decision making
A robust city modelling framework is essential if local, state and national governments and communities are to work together across complex multi-sectoral problems to improve urban liveability and climate adaptability. Currently, there is a lack of a publicly available, broadscale 3D digital representation of the impact of the urban landscape and building design on urban heat islands, street shading and walkability. This project aims to develop a demonstration digital twin which will embed the required analytics within a 3D city modelling framework to address these critical challenges within the built environment.
Digital twins have the potential to transform the design, management and performance of the built and natural environment. While a variety of digital twins support exploration, visualisation and analysis of multi-dimensional data, use cases that demonstrate the analytical power of digital twins – and specifically 3D and real-time data streams within an integrated analytical treatment for situational awareness – are still lacking. FrontierSI is determined to build spatial capabilities across government, industry and universities to enable the delivery of an ecosystem of integrated digital twins. Purpose-built use cases that are developed on common frameworks and are open standards-driven will contribute to the wider use of digital twins.
This project will pilot a digital twin illustrating how behaviour (that is, movements) change as a function of a complex interaction of environmental and physical conditions. Such conditions include the impact of 3D urban landscape and building design on urban heat islands, street shading and walkability, understanding walking behaviour as a function of heat, time of day, 3D structure and how, for example, this may allow mitigation and adaption to be designed concerning social distancing.
This collaboration aims to develop the following outcomes:
The pilot will concentrate on 3D analytics to urban micro-climate, including urban heat islands, temperature propagation, shadowing and its effect on pedestrian thermal comfort, mobility and walkability across selected urban scenarios in Western Sydney, a fast-developing area posing many challenges to urban planners and stakeholders. Once digital twin frameworks are further developed through use cases such as this pilot, there will be other application areas that will benefit, including construction, asset management and planning/design. This pilot will make progress towards a digital twin framework for data ingestion protocols, data management, workflows and real-time data analytics for situational awareness. It is designed to be scalable and transferable to other application domains, for example, melding 3D city models and real-time data streams to other problems.
This project is supported by FrontierSI, AURIN, UNSW Research Infrastructure and in collaboration with NSW Spatial Services, Data61, QLD DNRME and Astrolabe.
