We assume the node faces a stochastic flow of trucks delivering and retrieving containers from logistics companies (LCs), i.e., warehouses and terminals. During peak hours, trucks may stop at a parking area, where the ITT fleet, composed of manned or automated electric vehicles, takes over container transport between the parking area and the LCs. The decoupling decision determines whether trucks should proceed to their LC, park, or decouple. The decision model is based on several parameters, such as the estimated workload of the ITT fleet over a time window. We assess the decision model using a discrete event simulation model of the Port of Moerdijk, The Netherlands. This allows experimenting with various arrival patterns, earliness of information, the charging infrastructure, and decoupling decision parameters. The simulation model involves realistic traffic behavior, six decoupling scenarios, and more than 130 LCs. Through parameter calibration, the decision model capitalizes on early information to reduce truck turnaround time and truck-driven kilometers by up to 19%, preventing 14.4 metric tons of CO₂eq emissions per day and reducing the share of late containers by up to 10%.</p>","PeriodicalId":50259,"journal":{"name":"Journal of Advanced Transportation","volume":"2026 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/atr/8968454","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147714954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combined with semistructured interviews, we analyzed the characteristics and influencing factors of their activity spaces under different travel modes in urban areas. This study found that participants who primarily walked had limited, concentrated activity spaces. Participants who relied mainly on motor vehicles showed path dependence, with activity spaces following a linear distribution. In contrast, participants who used mixed travel modes, especially those traveling across regions, demonstrated broader and multicentered activity spaces. Additionally, this study found that time constraints significantly influenced the expansion of activity spaces. Retired participants exhibited more dispersed, exploratory trajectories, whereas commuting participants showed highly repetitive paths.

To overcome the limitations of traditional methods reliant on single information sources or advanced remote sensing equipment, this study constructs a multiscale information fusion framework for aircraft turbulence early warning. The framework initially screens key forecast indices from meteorological reanalysis data. Subsequently, dynamic modes strongly associated with turbulence are extracted via advanced signal decomposition to drive a large-scale background risk assessment model that integrates Gaussian process classifiers with an entropy-based weighting method. Concurrently, a small-scale turbulence life cycle model for vertical wind speed is developed through the analysis of high-frequency quick access recorder (QAR) data to capture real-time local variations and critical turbulence precursor characteristics. The core innovation of this framework lies in the utilization of an ensemble Kalman filter (EnKF) for dynamic fusion and state optimization of large-scale background risk, small-scale life cycle patterns (particularly precursor features), and high-frequency vertical wind speed observations. This fusion process exhibits a sensitive, trigger-like response to identified turbulence precursor signals, generating high-precision ensemble predictions of vertical wind speed, from which Eddy dissipation rate (EDR) is ultimately estimated for early warning. Experimental results, based on nearly 200 min of real flight data from various flights, demonstrate that the model not only achieves high-precision prediction of EDR evolutionary trends but also showcases superior warning performance, with an average precision of 95.5% being attained and an average effective early warning lead time of approximately 4 s being provided.

The results indicate that, as time goes by, the research hotspot has gradually shifted from the mixed traffic flow composed of different types of motorized vehicles with nonmotorized vehicles and pedestrians to the mixed traffic flow composed of networked self-driving vehicles and hand-driving vehicles. Meanwhile, subtopics in related fields such as vehicle trajectory prediction, ramp design, and traffic signal control have also attracted much attention of researchers. In addition, the popularization of the Green Travel concept has made research on hybrid traffic flow more focused on energy saving and environmental protection.

However, the traffic signal control (TSC) problem necessitates a single-agent framework, as a single control center monitors traffic conditions across all roads in the study area and coordinates the control of all intersections. This work proposes a novel single-agent RL-based urban corridor ATSC model: It abandons complex multiagent coordination and uses a single agent to centrally orchestrate signal timings across multiple intersections. Notably, the model is highly applicable to real-world settings. It defines state and reward functions based on a queue length metric—one that correlates with congestion and can be reliably estimated using probe vehicle data. Since probe vehicle data have become highly prevalent, this feature enables rapid, large-scale deployment. The single-agent framework primarily relies on a unique design of state, action, and reward. To facilitate learning and manage congestion, both state and reward functions are defined based on queue length, with actions designed to modulate queue dynamics. The queue length definition used in this study deviates slightly from conventional definitions but is closely correlated with congestion states. The method was comprehensively evaluated using the SUMO simulation platform under various traffic patterns. Experimental results show that the PPO algorithm demonstrates significantly faster learning than the DQN algorithm. The model effectively alleviates urban corridor congestion through coordinated multi-intersection control: During the simulation period of the entire scenario, the queue length did not exceed 50 vehicles, and instances where it exceeded 30 vehicles were relatively rare. Compared with the baseline scenario where queue lengths exceeded 150 vehicles, the proposed method significantly reduces road congestion. The work in this paper demonstrates the feasibility of controlling multiple intersections under a single-agent framework, and the control scope will be further expanded in the future.</p>","PeriodicalId":50259,"journal":{"name":"Journal of Advanced Transportation","volume":"2026 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/atr/5134018","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing domestic specifications lack explicit provisions regarding the structural design and load-bearing capacity of PCBs, presenting a critical bottleneck for the engineering application of temporary traffic barriers. To mitigate this limitation, a novel PCB was developed featuring a pre-embedded rectangular steel tube and I-beam joint, coupled with a single-slope cross-section (1200 mm in height), to satisfy the SB-level safety performance criteria specified in relevant standards. Distinct from conventional finite element simulation approaches, two full-scale vehicle impact tests were subsequently performed to verify the structural safety of the barrier.
