Bridge Dynamics Diagnostics through Pedestrian-Carried Smartphone Sensor Networks

Structural health monitoring (SHM) discipline proposes assessment solutions for structural safety empowered by sensor technologies. Traditional SHM faces fundamental challenges around time efficiency and the cost of instrumentation and workmanship. As a response to the financial and practical difficulties with up-to-date SHM techniques, this project brings together cross-disciplinary aspects; crowdsourcing, mobile sensing, and biomechanical systems for immense innovation in data collection. Specifically, we propose a citizen-engaged SHM formulation gathering data from pedestrians via carried smartphones and identifying bridge signature features despite complete freedom of pedestrian mobility, which has yet to exist in the existing literature.
