To help inform the business case for investment in digital twins we have set out sixteen high-level use case themes where digital twins can have a significant positive impact on the design and operation of Connected Places, ranging from real-time vehicle management through improving the design of future air mobility vehicles to dynamic grid load balancing. These use cases span all aspects of Connected Places including mobility, built environment, public spaces and infrastructure.

The specific, tangible form these use case themes will take on will differ somewhat between organisations (dependent on type and sector, but also digital maturity of the organisation). Nevertheless we have identified the broad value propositions, solution map and data requirements for each use case theme. The latter shows that many use cases are restricted by lack of open (or sharable) data: increasing the availability of data is likely to be a relatively quick win to enable deployment of digital twins.
