Title
(EN) OPTICAL FIBER SENSING FOR HIGHWAY MAINTENANCE
(FR) DÉTECTION À FIBRE OPTIQUE POUR ENTRETIEN D'AUTOROUTE
Abstract
(EN)
Aspects of the present disclosure describe systems, methods and structures employing optical fiber sensing to monitor highway/roadway/street conditions (i.e., potholes, pavement cracks, etc.) in real-time, continuously, and while the highway/roadway/street remains in operation (in-service monitoring). Systems, methods, and structures according to aspects of the present disclosure may employ machine learning (ML) algorithms including neural networks to provide and or report on highway conditions so monitored/sensed. Of further advantage, systems, methods, and structures for optical fiber sensing for highway maintenance may operate in real-time, continuously, long-term, in-service, and may employ existing telecommunications optical cables without additional deployment cost(s) or disruption of telecommunications traffic.

Des aspects de la présente invention concernent des systèmes, des procédés et des structures employant la détection à fibre optique pour surveiller des états de autoroute/route/rue (c'est-à-dire nids-de-poule, fissures de chaussée, etc.) en temps réel, en continu, et pendant que l'autoroute/route/rue reste en fonctionnement (surveillance en service). Des systèmes, procédés et structures selon des aspects de la présente invention peuvent employer des algorithmes d'apprentissage automatique (ML) comprenant des réseaux neuronaux pour fournir et/ou rapporter des états d'autoroute ainsi surveillés/détectés. Parmi d'autres avantages, les systèmes, procédés et structures pour la détection à fibre optique en vue d'un entretien d'autoroute peuvent fonctionner en temps réel, en continu, sur le long terme, en service, et peuvent employer des câbles optiques de télécommunications existants sans coût(s) de déploiement supplémentaire(s) ni interruption du trafic de télécommunications.
