The concept of 'digital twins' has evolved from engineering simulations into a transformative tool for urban planning. A digital twin is a virtual replica of a physical system, continuously updated with real-time data to mirror its current state. In cities, these models integrate data from sensors, traffic cameras, and utility networks, allowing planners to simulate the impacts of policy changes or infrastructure projects before implementation. For instance, a digital twin of a flood-prone district can model the effects of new drainage systems under various climate scenarios, reducing risks and costs. However, the reliance on massive data raises concerns about privacy and data security, as well as the risk of over-reliance on models that may not capture all social complexities. Thus, while digital twins offer unprecedented predictive power, their effective use requires balancing technological precision with human judgment and ethical oversight.
❓ According to the passage, what is a primary advantage of using digital twins in urban planning?
A. They eliminate the need for human decision-making in city governance.
B. They allow planners to test the outcomes of changes without real-world implementation.
C. They automatically solve all privacy and security issues related to urban data.
D. They provide a complete representation of all social interactions in a city.
✅ Correct Answer
B. B) They allow planners to test the outcomes of changes without real-world implementation.
