This paper systematically reviews the research progress in this field. First, the interfacial mechanical behavior under various loads is summarized: the constitutive models, failure mechanisms, and prediction methods under static, fatigue, and dynamic loads are discussed, highlighting strain rate effects and fatigue damage evolution as critical characteristics. Second, the environmental and time-dependent effects are analyzed, revealing the degradation mechanisms of interfacial performance due to environmental factors such as hygrothermal and freeze-thaw cycles, as well as the durability challenges posed by interfacial creep under sustained loads. Furthermore, the synergistic deterioration effects caused by multi-field coupling of mechanical and environmental factors are explored, and the application and limitations of intelligent methods like machine learning in interfacial performance prediction and damage monitoring are reviewed. Although existing studies have established some theories and models, significant challenges remain, including insufficient model universality, lack of standardized testing methods, unclear mechanisms of multi-factor coupling, and scarce long-term performance data. Future research should advance towards deeper mechanistic understanding and broader coupling investigations: cross-scale experiments and theories should be developed to reveal the fundamental failure mechanisms; systematic multi-field coupling tests simulating real service environments should be conducted to establish accelerated aging and life prediction frameworks; intelligent “gray-box” models integrating physical mechanisms with data-driven methods should be developed. The ultimate goal is to promote the establishment of a probabilistic time-dependent reliability design system, providing a theoretical foundation and standardization for the long-term safety of FRP-strengthened structures.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"13 4","pages":"Pages 1364-1429"},"PeriodicalIF":9.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148775787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a new graphics processing unit (GPU) enabled evolutionary dynamic programming (EDP) algorithm designed for rapid multi-source route and rescue planning, addressing the urgent need for real-time decision-making for first responders. It considers potential delays caused by unexpected railroad crossing blockages in densely populated metropolitan areas by incorporating real-time traffic information to identify an optimal route with the shortest response time during emergencies. Specifically, the EDP allows effective utilization of massive GPU computing threads for rapid and accurate pathfinding subject to train blockage constraints. A new method for GPU resource allocation at the structural level is also proposed, which constructs GPU threads as two-dimensional blocks to enable efficient route computation between a starting node and any nodes within the road network. The performance of our method is validated through case studies involving multiple emergency scenarios in the City of Columbia, SC. The results demonstrate that the method can find the optimal route with train blockage constraints within 1 s, a significant improvement over our prior method.

Under the condition of normal mineral powder consumption at 10% weight of SMPC, the high-temperature performance, low-temperature performance, and moisture susceptibility of SMPC all exhibited significant reductions as the polyurethane to aggregate ratio decreased. It is also found that the high-temperature performance and moisture susceptibility of SMPC could be improved by increasing the amount of mineral powder.

This fine-grained segmentation enables the vehicle to distinguish safe road surfaces, providing essential spatial understanding for real-time path planning, obstacle avoidance, and safe decision-making in complex traffic scenarios. However, conventional approaches often adopt an oversimplified definition of drivable areas, typically considering entire road surfaces as uniformly navigable. This assumption fails to account for real-world traffic constraints imposed by lane markings, thereby impacting the reliability of decision-making. To address this problem, we redefine pixel-level drivability based on traffic rules to interpret the scene and construct the lane line constrained drivable area detection (LCDAD) dataset. Based on this dataset, we conduct comprehensive evaluations of existing state-of-the-art methods. Considering the limitations of existing road segmentation methods, we propose a cross-attention fusion architecture to further enhance road scene understanding. Within this architecture, a self-attention mechanism is applied across the feature dimension rather than the spatial dimension, calculating the cross-covariance across feature channels to generate attention maps, making it more suitable for high-resolution drivable area detection. Extensive experiments on three public datasets demonstrate the effectiveness of the proposed framework, while detailed ablation studies confirm the superiority of the proposed fusion structure.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"13 4","pages":"Pages 1087-1099"},"PeriodicalIF":9.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148776189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By incorporating road users’ perceptions and experiences of safety deficits associated with the built infrastructure, the methodology provides valuable insights that complement traditional data sources. Crowdsourced danger spots and clusters of hard-braking events are validated through on-site audits to obtain objective safety ratings independently of crash data. A statistical analysis using a logistic regression model reveals that both crowdsourced danger spots and vehicle kinematics are statistically discernible factors for predicting safety ratings. Our results indicate a disproportionate representation of individual road user groups in crash data. This highlights the value of human-factor insights through crowdsourced data and vehicle telematics-based hard-braking events in augmenting crash-based analysis.

To address these research gaps, this paper presents an innovative method for measuring the regularity of individual users, which considers the repetition of basic travel behaviors along with temporal, spatial, and frequency dimensions. Applying this method to historical trip data from bike-sharing and subway systems has illustrated the effectiveness and applicability of the approach proposed in this paper.

Compared with static scanners, vehicle-mounted scanners are widely used because of their high inspection efficiency. However, two major challenges remain in practical applications: (i) a trade-off between testing speed and measurement accuracy, and (ii) limited adaptability to pavements with different brightness levels under varying illumination conditions. Under high-speed scanning, the exposure time must be shortened to maintain a small longitudinal sampling interval, which reduces the reflected laser energy captured by the camera during each profile acquisition. This problem becomes more severe for low-reflectivity dark asphalt pavements, leading to insufficient returned laser intensity, invalid profile points, and increased measurement errors. To address this issue at the data-acquisition stage, a high-precision vehicle-mounted laser scanning system (HVLS) equipped with a supplemental lighting device was developed in this study. The supplemental lighting device provides additional 405 nm illumination aligned with the built-in laser line, thereby enhancing the reflected laser signal under short-exposure conditions. This system meets the sampling requirements for macroscopic texture in the direction of travel across a wavelength range of 0.5–50 mm. It improves high-speed pavement macro-texture measurement with a longitudinal sampling interval of 0.2 mm and increases the scanning speed by up to 300% compared with the HVLS without supplemental lighting, without compromising the accuracy of MPD, Ra, and RMS measurements.
