However, existing studies often disregard empirical distribution, heterogeneity, and heteroscedasticity of alighting patterns at disaggregate run-level resolution. Machine learning (ML) models, although capable of modeling complex relationships, are often replaced by traditional methods due to interpretability needs in policymaking. Therefore, this paper investigates factors influencing bus alighting behavior using ML techniques, namely decision tree, random forest, and gradient boosting (GB), and compares against a traditional ordinary least squares (OLS) model to evaluate prediction accuracy, variable impacts, and robustness at the run level with electronic ticketing data from Chennai, India. Results show that GB outperforms OLS with a 51% improvement in mean squared error (MSE) (from 2.50 to 1.23) and a 41% improvement in root mean squared error (RMSE) (from 3.76 to 2.21), respectively. It also effectively addresses zero inflation, heterogeneity, and heteroscedasticity without data transformation. Passenger occupancy, a real-time operational variable, explained 29% of total variability, capturing dynamic conditions that static variables cannot. The ‘neighborhood attraction points’ category accounts for 6.5% of the total variation, revealing trip-chaining and substitution effects at not only the current but also preceding and subsequent stages. Coarser resolution data (e.g., hourly/daily) cause inaccurate generalizations and reduce variables’ significance, emphasizing the need for finer run-level resolution for robust predictions. A practical application of the proposed model demonstrates that increasing ordinary bus services from the current 7–9% optimizes ridership by balancing enhanced users’ affordability with minimized revenue loss for transit operators.</div></div>","PeriodicalId":52282,"journal":{"name":"International Journal of Transportation Science and Technology","volume":"23 ","pages":"Pages 115-136"},"PeriodicalIF":5.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149078751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, automatically detecting pavement distress from image samples remains challenging due to complex asphalt textures, including variations in aggregate size, surface wear, and non-distress-related artifacts like shadows and tire marks. This study addresses these challenges by screening and optimizing texture descriptors to characterize local structures and patterns of image regions containing pavement distress. An automated detection system is developed using four categories of texture descriptors: (1) original image-based parameters, (2) multi-resolution analysis-based texture features, (3) local binary pattern (LBP) and their variants-based texture features, and (4) gray-level co-occurrence matrix (GLCM)-based texture features. Unlike previous studies that rely on a single type of descriptor, this integrated approach processes both two-dimensional (2D) intensity images and three-dimensional (3D) pavement surface models, capturing global and local texture patterns to improve robustness and feature discriminability for distress classification. A total of 196 optimal feature descriptors are selected to represent images from both imaging modalities, forming the basis of a distress classification model. A dataset comprising 4 932 samples across 8 distress categories, with moderate class imbalance, is constructed to compare the performance of random forest (RF), gradient boosting decision tree (GBDT), multilayer perceptron (MLP), and support vector machine (SVM) in distress classification. Class-weighted training and balanced performance metrics were used to mitigate class imbalance effects and ensure robust model evaluation. Among these, the SVM classifier demonstrates the best predictive performance and robustness. Extensive experiments, including feature combination analysis and ablation studies, identify the optimal feature set comprising original image-based, multi-resolution analysis-based, and LBP variants-based descriptors. This feature set achieves a classification accuracy rate (CAR) of 0.896, an F1-score of 0.894, and an area under receiver operating characteristic curve (AUC) of 0.938 across all distress categories. The selected descriptors effectively differentiate pavement distress types, providing a reliable automated classification system.</div></div>","PeriodicalId":52282,"journal":{"name":"International Journal of Transportation Science and Technology","volume":"22 ","pages":"Pages 383-409"},"PeriodicalIF":5.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148545089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, the model utilizes ensemble learning techniques, integrating multiple machine learning algorithms to predict accident severity and identify key contributing factors accurately. Then, an ordered logit regression model is1 employed to examine critical variables affecting accident severity, such as the level of the automated driving system, pre-collision vehicle speed, and collision site.
