Data come from the British Columbia Activity Time Use Survey (BC ATUS) conducted in 2023, which collected individuals’ ranked preferences for charging their EVs in the following location alternatives: home, work, grocery stores, shopping malls, en-route, gas stations, and other locations. A random parameter rank-ordered logit (RPROL) model is employed to capture the relative preferences for different charging locations. The results reveal that individuals’ socio-demographics, travel attributes, built-environment characteristics, and accessibility measures significantly influence EV charging location preferences. For example, higher-income individuals show higher preferences for charging at home and workplace. Residents of detached houses prefer home and workplace charging over grocery stores and shopping malls. Apartment dwellers show higher preferences for charging their vehicles in grocery stores, shopping malls, gas stations, and other locations. Additionally, individuals traveling longer distances daily are likely to have higher preferences for charging their EVs in shopping malls, en-route, and gas stations. The proximity of charging stations and land use mix also play a critical role in influencing charging location preferences. A higher number of charging stations near home is found to reduce the preferences for home charging. On the other hand, a higher land use mix around workplaces, indicating the availability of diverse amenities, reduces the preferences for workplace charging. Providing community-based charging facilities might be able to accommodate the EV charging needs of these individuals. Nevertheless, the findings of this study provide valuable insights for policymakers and planners regarding user preferences for charging, which will help in strategic investments, planning, and EV charging infrastructure development.</div></div>","PeriodicalId":52282,"journal":{"name":"International Journal of Transportation Science and Technology","volume":"23 ","pages":"Pages 21-35"},"PeriodicalIF":5.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149078707","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}

We model the task in the context of the SEAD mission, where UAV range trajectories, flight energy consumption, and threat values are used as optimization objectives. To solve the model and overcome the inefficiency of traditional ant colony optimization (ACO) algorithms in dealing with complex UAV trajectory planning problems in a 3D environment, we propose the Improved ant colony optimization (IACO) algorithm for multi-UAV trajectory planning. First, we improve the transfer probability function, heuristic function, and pheromone updating rule of the original ACO algorithm to improve the practicality of the algorithm in complex environments. Second, the unevenly distributed initial pheromone and the turn angle restriction are introduced to make the planning trajectory more consistent with the actual flight requirements of UAVs. Finally, simulation comparison experiments are carried out in a 3D environment with the background of multiple UAVs performing SEAD tasks cooperatively. The experimental results show that the IACO algorithm performs better, with planned trajectories passing through fewer nodes and achieving improved performance in terms of duration, energy consumption, and threat value.

A two-stage stochastic optimization model is developed to strategically manage the transportation of containers from multiple origins to designated intermodal hubs. By leveraging spot capacities at train stations and addressing uncertainties in demand and train capacity, the model integrates conditional value-at-risk (CVaR) to balance cost efficiency and risk management, enabling robust decision-making under uncertainty.

The ideal fiber dosages are found to be 0.75 kg/m³ (PPFs), 2.5 kg/m³ (SPFs and FFs), and 25 kg/m³ (SFs), maintaining concrete strength.

However, automatic detection of pavement crack is a challenging industrial problem due to the background noise interference and complex crack structures. In this paper, a novel crack detection method based on multi-scale dilated spatial attention (MSDA) mechanism is proposed for pavement crack detection, named as PCMSDA. First, an MSDA module is designed for feature extraction, which aggregates semantic information to enhance crack features and obtain richer texture details, thereby strengthening the representation of crack features. The MSDA module can effectively preserve the crack features of shallow networks, avoid discontinuities in cracks, and reduce interference of background noise. Meanwhile, in the upsampling process, a content-aware reassembly of features (CARF) module is designed. In the CARF, the input feature maps are utilized to predict the upsampling kernels, where each position employs a different upsampling kernel. Subsequently, feature reassembly is carried out based on the predicted upsampling kernels. While introducing relatively less computational overhead, this approach can aggregate contextual information and effectively preserve the detailed features of cracks, enabling the model to effectively detect pavement cracks. To validate the effectiveness of the proposed PCMSDA, extensive experiments are validated on the real pavement crack dataset. Experimental results demonstrate that the proposed PCMSDA achieves better performance than state-of-the-art pavement crack detection models.</div></div>","PeriodicalId":52282,"journal":{"name":"International Journal of Transportation Science and Technology","volume":"23 ","pages":"Pages 86-98"},"PeriodicalIF":5.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149078749","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}
