Monitoring-data-driven reliability assessment of bridge infrastructure uses structural health monitoring, inspection, load testing, bridge weigh-in-motion, visual/non-destructive testing (NDT) data and digital twins to characterize evolving condition and failure risk. This review asks how monitoring data are transformed into reliability inputs, how model updating methods complement one another, how limited data support time-dependent reliability and rare-event estimation, and how updated reliability supports maintenance decisions. A Scopus-based search of English journal papers published from 2020 through the 30 June 2026 search cutoff was conducted using keywords on bridges, monitoring data, model updating, reliability/risk assessment and maintenance. After thematic screening, 114 papers were coded and critically synthesized, comprising 56 core bridge studies and 58 supplementary studies retained only for method transfer or comparison. The review establishes a technical chain from monitoring data to structural state characterization, model updating, uncertainty quantification, reliability/risk assessment and maintenance decision-making, and formulates a probabilistic framework based on observation models, state/parameter updating, posterior predictive reliability and risk- and loss-based decision-making. The findings show that finite-element updating contributes physical interpretability, Bayesian updating supports evidence fusion and posterior uncertainty, filtering enables online recursion, surrogate modelling and machine learning reduce computational burden, and digital twins are meaningful only when data assimilation, uncertainty propagation, reliability calculation and decision feedback are integrated. Future work should strengthen traceable data-to-limit-state mappings, explicit treatment of model-form and measurement errors, tail failure-probability estimation under sparse monitoring data, and closed-loop reliability-informed bridge maintenance.

Unsafe conditions of objects are major contributors to construction accidents such as falls, strikes, and collapses. Although traditional inspections and existing vision methods can detect objects, they often fail to infer their potential risks. To overcome this limitation, this paper proposes a deep identification method integrating visual attribute representations. We introduce the high-level concept of visual unsafe attributes to describe hazards arising from an object’s shape, state, and environmental context. Based on accident text analysis, a visual attribute system covering four risk types—fall, strike, collapse, and rollover—is established, and the VALD dataset is built by extending SODA dataset. An integrated detection framework based on YOLOv11 is then developed to achieve end-to-end joint inference of object locations and unsafe attributes. The model is trained and evaluated on VALD. Experiments show mAP@50 of 84.8%, recall of 91%, and F1-score of 0.82, with improvements of 21.1%, 33.6%, and 0.175 over models without attention mechanisms. These results demonstrate that visual attribute representation and attention significantly enhance risk feature extraction. The resulting dynamic risk assessment system quantifies object-strike scenarios spatiotemporally, providing a real-time and interpretable safety monitoring solution for construction sites.
