This study presents an integrated framework for multiple traffic anomaly detection on highways using vehicle trajectories. The framework addresses both macroscopic congestion patterns and microscopic driving behaviors, offering a comprehensive solution that simultaneously detects multiple anomalies within a unified framework. The developed framework comprises three main components: data acquisition and preprocessing, vehicle trajectory recognition, and traffic anomaly detection. The former two components are responsible for acquiring real-time vehicle trajectories on highways. With such trajectory information and the continuously monitored short-term traffic state, the latter component seeks to simultaneously detect all the traffic anomalies via a tailored sub-algorithm for each of them. For macroscopic anomaly detection, an algorithm for detecting stop-and-go waves by constructing localized shockwaves is proposed to capture the propagation of traffic congestion waves even in limited field-of-view scenarios. For microscopic anomaly detection, a dynamic background traffic state updating mechanism is introduced, allowing the framework to adaptively integrate historical traffic data and environmental factors. Additionally, a double-layer stacking framework based on unsupervised methods is designed to integrate diverse feature types and addressing perspective distortions. The developed framework is tested in experiments on both simulation and real-world data on highways. The results confirm its effectiveness in the simultaneous detection of multiple traffic anomalies within an integrated framework.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"94 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884948","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 standard link transmission models fall short of reproducing traffic phenomena such as capacity drop (CD). Moreover, traffic control measures such as variable speed limits (VSLs) control may change the fundamental diagram and should be captured by traffic flow models. This study proposes a first-order link-based flow model incorporating VSL and CD for freeway simulation. In the proposed model, the vehicle flow through each link is characterized by cumulative inflow and outflow, which are influenced by the time-varying free flow speed caused by the VSL at the link's upstream boundary. CD is modeled by incorporating the traffic state-dependent capacity at the freeway lane-drop positions. A node model is then developed to determine and regulate the flow propagation between adjacent links. Simulation experiments were conducted on freeways to evaluate the model's effectiveness. The results demonstrate its ability to accurately predict traffic operations under VSL and CD while maintaining a computationally tractable representation of flow propagation.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"32 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862456","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}

Brody","doi":"10.1111/mice.13490","DOIUrl":"https://doi.org/10.1111/mice.13490","url":null,"abstract":"High-resolution flood probability maps are instrumental for assessing flood risk but are often limited by the availability of historical data. Additionally, producing simulated data needed for creating probabilistic flood maps using physics-based models involves significant computation and time effort, which inhibit its feasibility. To address this gap, this study introduces Precipitation-Flood Depth Generative Pipeline, a novel methodology that leverages generative machine learning to generate large-scale synthetic inundation data to produce probabilistic flood maps. With a focus on Harris County, Texas, Precipitation-Flood Depth Generative Pipeline begins with training a cell-wise depth estimator using a number of precipitation-flood events model with a physics-based model. This cell-wise depth estimator, which emphasizes precipitation-based features, outperforms universal models. Subsequently, the conditional generative adversarial network (CTGAN) is used to conditionally generate synthetic precipitation point cloud, which are filtered using strategic thresholds to align with realistic precipitation patterns. Hence, a precipitation feature pool is constructed for each cell, enabling strategic sampling and the generation of synthetic precipitation events. After generating 10,000 synthetic events, flood probability maps are created for various inundation depths. Validation using similarity and correlation metrics confirms the accuracy of the synthetic depth distributions. The Precipitation-Flood Depth Generative Pipeline provides a scalable solution to generate synthetic flood depth data needed for high-resolution flood probability maps, which can enhance flood mitigation planning.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"23 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862457","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}

Accurate and timely crack assessment and prediction are crucial for effective road maintenance, but existing studies often rely on individual indicators such as crack types, attributes, and severity, which fail to capture the full complexity of crack deterioration. Furthermore, limited research has explored the long-term impacts of traffic, socioeconomic, and climate changes on crack progression, and existing machine learning (ML) models struggle to explain the contributions of individual predictors due to inherent complexities in such spatial data. This study develops a geocomplexity-enhanced ML (GML) approach to evaluate crack deterioration and predict cracks under various future scenarios in the Wheatbelt region of Australia. The study employs laser-scanning data to generate a novel cracking performance index (CPI) and integrates geocomplexity (GC) measures with random forest models to capture local spatial complexities. Results demonstrate that GML significantly outperforms standard ML models in predicting CPI-based crack deterioration. Crack predictions in future scenarios reveal that in the Wheatbelt region, changes in climate factors over time have a more substantial impact on crack progression than traffic and socioeconomic changes, and without effective maintenance, crack propagation rate will significantly increase. It provides empirical evidence for developing preventive maintenance strategies. The developed methods and findings can support the development of adaptive, climate-resilient infrastructure, and long-term road management strategies, enhancing the sustainability of transport infrastructure.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"17 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849405","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}

It allows for the scaling of measurements from the real world to the corresponding nondimensional form of the physical system. The methodology begins by constructing the non-homogeneous terms of the equations using parameters and variables observed in the real world. Subsequently, utilizing second-order theory induced by incremental loads during step loading, the decoupling and identification of prestress force and bending rigidity are accomplished. The identification algorithm is constructed by integrating the nondimensional form of the iBCE with physics-informed neural networks. Without any additional regularization, the rationality and adaptability of this methodology are validated by nine examples that exhibit no nonlinear relations. A comprehensive series of systematic studies indicates that high accuracy can be achieved with the decoupled algorithm. This accuracy is possible when one mechanical parameter, such as bending rigidity or prestress force, is known and utilized to identify the remaining parameter. When both mechanical parameters are unknown, investing more in training costs enables the inverse identification of multiple parameters. Even with a 1% noise level, reasonable accuracy in the decoupling and identification of two mechanical parameters can be achieved. This methodology avoids the traditional limitations associated with solving the forward and inverse problems of incremental differential equations and transcendental equations.","PeriodicalId":156,"journal":{"name":"Computer-Aided Civil and Infrastructure Engineering","volume":"15 1","pages":""},"PeriodicalIF":11.775,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849407","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}
