An Intelligent Acoustic Emission System for Active Anomaly Identification and Traffic Control of a Highway Viaduct †

This project describes how we built and tested an intelligent acoustic‑emission (AE) monitoring system that can spot structural problems in real time and trigger active traffic control on highway viaducts. Highway viaducts are essential pieces of infrastructure that constantly experience dynamic loads, weather‑related wear, and possible damage. Conventional inspections usually cannot give the continuous, real‑time information needed for proactive safety management. Our approach combines very sensitive AE sensors with modern signal‑processing algorithms. The system can detect, locate, and classify micro‑cracks and other active defects while traffic is moving. It also links the health‑monitoring data to a traffic‑control module, so speed limits can be adjusted and lanes closed automatically when serious

anomalies appear. We used numerical simulations and structural models to test how well the AE system senses localized damage growth and how effectively the integrated traffic‑control response reduces structural stress. The work offers detailed guidance for creating smart infrastructure that connects structural health monitoring with active traffic management.
