KE-H-GNN integrates a deep learning predictive model with traffic engineering domain knowledge and a multi-linear regression (MLR) module for incorporating external factors. Leveraging insights from the gravity model, we propose two meaningful region partitioning strategies for reducing data dimension: election districts and K-means clustering. The aggregated OD matrices and graph inputs are processed using an long short-term memory network to capture temporal correlations and a multi-graph input graph convolutional network module to capture spatial correlations. The model also employs a global–local attention module, inspired by traffic flow theory, to capture nonlinear spatial features. Finally, an MLR module was designed to quantify the relationship between OD matrices and external factors. Experiments on real-world datasets from New York and Tokyo demonstrate that KE-H-GNN outperforms all the baseline models while maintaining interpretability. Additionally, the MLR module outperformed the concatenation method for integrating external factors, regarding both performance and transparency. Moreover, the election district-based partitioning approach proved more effective and simpler for practical applications. The proposed KE-H-GNN offers an effective and interpretable solution for ODP that can be practically applied in real-world scenarios.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"125 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing load identification methods typically rely on collecting vehicle load data from weigh-in-motion (WIM) systems when vehicles pass over them. However, cumbersome installation, high costs, and regular maintenance are the main obstacles that prevent WIM from being widely used in practice. This study introduces the visual WIM (V-WIM) framework, a vision-based approach for tracking and identifying moving loads. The V-WIM framework consists of two main components, the vehicle weight estimation and the vehicle tracking and location estimation. Vehicle weight is estimated using tire deformation parameters extracted from tire images through object detection and optical character recognition techniques. A deep learning-based YOLOv8 algorithm is employed as a vehicle detector, combined with the ByteTrack algorithm for tracking vehicle location. The vehicle weight and its corresponding location are then integrated to enable simultaneous vehicle weight estimation and tracking. The performance of the proposed framework was evaluated through two component validation tests and one on-site validation test, demonstrating its capability to overcome the limitations of existing methods.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"89 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition of these components significantly impacts the safe operation of the catenary, necessitating periodic inspections to detect defects. This task is typically performed by onboard cameras using computer vision. However, traditional image processing methods often focus on shallow features, making it difficult to handle the interference from complex structures of components. While deep learning methods have strong capabilities in capturing semantic features, the lack of crack samples makes reliable crack identification challenging. Therefore, a joint approach for crack detection based on structural perception is proposed. The approach integrates three main components: object structure perception, stick structure perception, and crack defect detection. A multistream catenary components segmentation network (MCSnet) is employed to extract structural features of the DB and SC. Subsequently, an adaptive stick perception method (ASPM) is applied to identify potential crack candidates based on stick structure. The combined structural features enable effective detection of crack defects. Experimental results validate the effectiveness of the proposed approach.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"69 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, enhancing the reliability of the prediction models with better generalization capability and quantifying the uncertainties of their predictions is significant. However, existing mechanism-driven and data-driven prediction models for reliable engineering applications incorporate complicated modifications on models and are sensitive to the precision of relevant prior knowledge. Focusing on these issues, a novel and concise data-driven approach, named “R2CU” (stands for transforming regression to classification with uncertainty-aware), is proposed to introduce the relative <i>fuzzy prior knowledge</i> into the data-driven prediction models. To enhance generalization capacity, the conventional regression task is transformed into a classification task based on the fuzzy prior knowledge and the experimental data. Then the aleatoric and epistemic uncertainty of the prediction is estimated to provide the confidence interval, which reflects the prediction's trustworthiness. A validation case study based on shear capacity prediction of reinforced concrete (RC) deep beams is carried out. The result proved that the model's generalization capability for extrapolating has been effectively enhanced with the proposed approach (the prediction precision was raised 80%). Meanwhile, the uncertainties within the model's prediction are rationally estimated, which made the proposed approach a practical alternative for structural performance prediction.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"23 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the track condition evolution presents challenges to accurate prediction, with diverse influential factors resulting in heterogeneous degradation patterns across space and time. In a short-term context, time series derived from historical records are length-limited, with sparse sampling points complicating feature identification. Actual activities, particularly minor repairs, lack strict periodicity, leading to irregular spans in continuous degradation curves, yielding nonuniform samples. This study leverages dynamic inspection and influential factors to propose an ensemble learning using the Transformer model. The outer framework employs unsupervised learning to group the sections based on specific time periods and track lengths. It assigns fuzzy logic categories to these groups to capture differentiated patterns and guides the division of samples into fuzzy subsets and assigns them to the learners corresponding to each cluster. The loosely coupled structure aids task decomposition and enhances local performance. The inner model refines the Transformer design for a new scenario, introducing a prediction objective transformation based on the interdependencies among multidimensional indicators to strengthen feature extraction. The prediction performance is evaluated using over 2 years of records from 560 km railway lines, offering insights for improving onsite track management.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"92 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to address computation efficiency and accuracy issues in binocular camera-based 3D structural displacement measurement by proposing a lightweight binocular vision-supported framework for structural 3D dynamic response monitoring. Through the optimization of sub-algorithms and code structures, this framework enhances both measurement accuracy and computational efficiency. The research incorporates a hybrid feature point processing algorithm and a lightweight tracking algorithm, which improve the accuracy of feature point recognition and tracking, enhance the adaptability and flexibility of the monitoring process, and increase tracking efficiency and overall system performance. These improvements make the framework more applicable to various civil engineering scenarios. Experimental validation on a full-scale three-story structure shows that the framework enables effective, target-free, 3D dynamic monitoring. Compared with reference displacement sensors, the framework achieves a relative root mean squared error of 14.6%, closely matching the accuracy of traditional methods that utilize accelerometers. The framework processes 1000 frames at 9.2 frames per second, offering a novel solution for contactless structural dynamic response monitoring in civil engineering applications, such as residential buildings and bridges, within a reasonable distance.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"24 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A graph contrastive learning model is proposed to extract meaningful node embeddings that incorporate topology and attribute similarity information. Based on the learned node embeddings, the partition is determined by a parameter-free hierarchical clustering method and a subregion identification algorithm. Boundary tuning is then modeled as a bi-objective optimization problem to maximize regional homogeneity and compactness. A Pareto local search algorithm is developed to approximate the Pareto front.

However, the effectiveness of QV is impeded by the limited visual range of its hardware, resulting in suboptimal image quality for distant portions of the sewer network. Image super-resolution is an effective way to improve image quality and has been applied in a variety of scenes. However, research on super-resolution for sewer images remains considerably unexplored. In response, this study leverages the inherent depth relationships present within QV images and introduces a novel Depth-guided, Reference-based Super-Resolution framework denoted as DSRNet. It comprises two core components: a depth extraction module and a depth information matching module (DMM). DSRNet utilizes the adjacent frames of the low-resolution image as reference images and helps them recover texture information based on the correlation. By combining these modules, the integration of depth priors significantly enhances both visual quality and performance benchmarks. Besides, in pursuit of computational efficiency and compactness, a super-resolution knowledge distillation model based on an attention mechanism is introduced. This mechanism facilitates the acquisition of feature similarity between a more complex teacher model and a streamlined student model, with the latter being a lightweight version of DSRNet. Experimental results demonstrate that DSRNet significantly improves peak signal-to-noise ratio (PSNR) and and Structural Similarity index (SSIM) compared with other methods. This study also conducts experiments on sewer defect semantic segmentation, object detection, and classification on the Pipe data set and Sewer-ML data set. Experiments show that the method can improve the performance of low-resolution sewer images in these tasks.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"48 9 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143575368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
