According to motor vehicle collision reports from the Saudi Ministry of Health, 3,202 children younger than 18 years were involved in RTAs in 2020, resulting in 587 fatalities. Moreover, the World Health Organization reports that the use of child restraint systems (CRS) can reduce infant deaths by up to 71% globally.

Vehicle movement trajectories through curves are captured &lt;i&gt;via&lt;/i&gt; integrated UAV aerial photography systems and onboard vehicle recorders. High-precision spatiotemporal coordinates with dynamic parameters (instantaneous velocity and acceleration) are extracted using the professional trajectory analysis software. To address noise interference in raw trajectory data, a Kalman filtering algorithm is implemented for optimal motion state estimation and data smoothing. At the model architecture level, we propose a CNN-LSTM hybrid predictive model that synergistic-ally combines the spatial-temporal feature extraction capabilities of convolutional neural networks with the temporal dependency modeling advantages of long short-term memory networks, enabling end-to-end learning for quantitative trajectory conflict prediction. To validate model generalizability, this study concurrently constructed multiple benchmark models-including Support Vector Machine (SVM), Gradient Boosted Trees (XGBoost), GNN-LSTM, Vanilla LSTM, and Bi-LSTM-for comparative experiments. The evaluation framework employed a rigorous multi-dimensional validation protocol from machine learning, assessing all models not only by fundamental classification accuracy but also through fine-grained efficacy metrics (Precision, Recall, F1-score). Results demonstrated the superior performance of the hybrid CNN-LSTM model in predicting traffic conflicts at curves. Ultimately, curve-specific conflict probabilities were derived by applying the CNN-LSTM model to experimental data analysis. The generalization performance under class-imbalanced conditions was quantified using the Area Under the Receiver Operating Characteristic Curve (AUC-ROC), while prediction accuracy was validated through metrics including classification accuracy. This establishes a comprehensive multi-capability evaluation framework covering model stability, sensitivity, and generalization capability.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Empirical results confirm the CNN-LSTM model's superior performance in sharp-curve conflict prediction, achieving a mean accuracy exceeding 85%, precision above 82.7%, recall over 89.9%, and F1-score surpassing 86.1%, complemented by a 93.5% or higher average AUC-ROC that demonstrates robust generalization in class-imbalanced scenarios.

Particularly in high-risk road sections such as mountainous areas and steep downhill stretches, Emergency Escape Ramps (EERs) play a crucial role in preventing severe accidents caused by out-of-control vehicles. Accurate detection of these ramps is essential for enhancing road traffic safety.</p><p><strong>Methods: </strong>To address the limitations of existing methods, such as inadequate segmentation accuracy and poor robustness in object detection, this paper proposes a new model (HR-YOLO) that integrates the HR-Net model with an improved YOLOv12 model. To support the segmentation and detection of emergency escape ramp scenarios, we constructed a custom dataset consisting of 411 annotated images across 8 categories. This dataset reflects typical road environments and object types encountered in emergency ramp areas, providing a reliable foundation for model training and evaluation.</p><p><strong>Result: </strong>The HR-Net achieves a mIoU and mPA of 85.50% and 91.23%, respectively. The YOLOv12 network attains a mAP and F1 score of 78.7% and 75.9%, respectively, for unsegmented images. The YOLOv12 model enhanced with Coordinate Attention (CAYOLOv12) is combined with the HR-Net model. Compared to the standalone YOLOv12 model, the HR-YOLO model improves mAP and F1 scores by 10% and 9.6%, respectively.</p><p><strong>Conclusions: </strong>The proposed approach provides an efficient and reliable technological solution for the intelligent recognition of key infrastructure in traffic safety monitoring systems.</p>","PeriodicalId":54422,"journal":{"name":"Traffic Injury Prevention","volume":" ","pages":"1-8"},"PeriodicalIF":1.9,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145304592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
