Smart infrastructure is a research area focused on integrating technology and data into traditional infrastructure systems such as transportation, energy, water, and buildings. The goal of smart infrastructure is to enhance the efficiency, sustainability, and resilience of these systems by utilizing sensors, communication networks, and data analytics to monitor, control, and optimize their performance. This research area also involves the development of innovative technologies and strategies to improve the operation and maintenance of infrastructure assets, as well as to mitigate risks and respond to emergencies. Overall, smart infrastructure aims to create more connected, responsive, and intelligent systems that can support the growing needs of urban populations and improve the quality of life for residents.
