How Digital Twin Technology Could Pave the Way to Smarter Cities Image Credit: Vasin Lee/Shutterstock.com Everything in a smart city is interconnected via a network of sensors or electronic devices that gather data; this data is used to improve the functioning of the city. But this can be complicated and expensive if not thoroughly tested first. Just like their precursor, simulation, digital twins are a way of creating a virtual depiction of something in the real world such as a car or city. Smart cities can utilize digital twin technology to determine how the smart network might work, make adaptations and iron out any kinks, and determine the benefits.
