Digital Twin Technology and Its Impact on Infrastructure in India
With Applications Across Key Sectors and Global Comparisons
Introduction
Digital Twin Technology—virtual replicas of physical assets or systems—is revolutionizing infrastructure development globally. In countries like India, where massive infrastructure investment is underway across highways, cities, ports, railways, and utilities, digital twins offer an unprecedented opportunity to optimize planning, reduce costs, improve safety, and enhance sustainability.
This article explores how digital twin technology is being applied across key infrastructure sectors in India, lessons from other large economies, and the way forward for leveraging this cutting-edge tool at scale.
What Is Digital Twin Technology?
A Digital Twin is a dynamic, real-time virtual model of a physical object, process, or system. Powered by IoT sensors, AI, machine learning, and data analytics, it enables simulation, monitoring, and predictive insights across the asset’s entire lifecycle—from design to decommissioning.
