In summary, combined with the Internet of Things technology, sensors like fiber optic cable and wireless sensor can play an important role in the designing, monitoring and maintenance of our <span font-size:16px;">infrastructures. And this provides exciting opportunities for CEE to understand the real perance of infrastructure and construction. Meanwhile, we researchers need to quantify the value of sensing for smart infrastructure. Fortunately, micro-simulations at the city scale is becoming possible and we have a chance to model large scale systems in real time.
