| Abstract | |
We investigate the viability of using legacy fiber infrastructure to support future smart cities using distributed fiber optic sensing (DFOS) for traffic control. We carry out a field trial using fibers installed along the university campus and a dedicated camera for traffic parameter estimation. The novel YOLOv8 pattern recognition model applied to recorded video sequences is used as a reference to validate the implemented phase-sensitive optical time-domain reflectometer (phi-OTDR). The collected phi-OTDR data is manually annotated and compared to the YOLOv8 data used as ground truth. The results indicate that the implemented phi-OTDR setup successfully detects heavy vehicle traffic. (AU) | |
