By combining traditional algorithms with a decision tree ensemble model, a stacked predictive framework is constructed and trained on these extracted traffic characteristics. The model is applied and validated using data from the Fujiangsha waters of the Jiangsu section of the Yangtze River. Comparative analysis reveals that this model consistently outperforms traditional algorithms and ensemble models, maintaining stable accuracy above 98% across diverse scenarios.

Despite connected and automated vehicle (CAV) technology revolutionarily enables individual-level cooperative control, most existing studies have limited capability in simultaneously considering lane-changing and car-following behaviours of vehicles while passing through continuous intersections. This study proposes a novel trajectory optimisation method for a mixed fleet of CAVs and human-driven vehicles, including lateral and longitudinal behaviour control. The method constructs a lane-changing trajectory optimisation model based on the lane-changing intention generated by CAVs and formulates safety constraints, lane occupancy state assignment and lane-changing cost function constraints. It also establishes a longitudinal following model based on vehicle role switching protocols to realise different constituent fleets passing through signalised intersections with minimal stops. Simulation results show that the proposed method can reduce the average travel time by up to 26.77%, decrease average travel delay by up to 42.66%, minimise the average number of stops by up to 91% and lower fuel consumption and pollutant emissions by more than 28%. After multiple independent experiments are conducted, the 95% confidence intervals are determined as follows: [101.09 s, 101.53 s] for average travel time, [49.77 s, 50.17 s] for travel delay and [111.22 g, 132.38 g] for fuel consumption. Parking behaviour analysis yields [0.68 s, 0.86 s] for average parking time and [0.16, 0.18] occurrences per vehicle for stop frequency. Sensitivity analyses of signal cycle length and guidance zone length demonstrate that the guidance effect of the proposed control strategy is stable under various settings.</p>","PeriodicalId":50381,"journal":{"name":"IET Intelligent Transport Systems","volume":"19 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/itr2.70048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148507","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}

To achieve this, an effective approach to virtually merge trains into the same convoy, operating safely in normal situations and in emergencies, is essential. This paper proposes a new virtually coupled train control model based on the vehicle-following approach and operational hazard analysis that can ensure safe operation. Unlike existing models in previous works, the proposed model is generalised and flexible for real operations, allowing for the coupling of different train types with varying acceleration and deceleration capabilities and variable safe separation distance. The comprehensive set of operational states is created by adopting the labelled transition system to determine all interconnected state movements which can control the following train based on the preceding train operation. Suitable acceleration and deceleration equations for initial, virtual coupling, and emergency states are introduced to improve coupling capability and ensure safety in all operational states. Moreover, the minimum safe distance equation is modified to ensure safety and provide riding comfort by preventing fluctuating movement of trains in the convoy. The proposed model was simulated by using MATLAB and applied to a 250 km high-speed train line linking Thailand and Laos. The simulation includes normal train operations, varying acceleration and deceleration capabilities, communication time delays, and emergency scenarios such as unintentional stops, communication loss, and temporary speed restrictions. The simulation results demonstrate that the proposed model can accommodate virtual coupling of any train type, various braking capabilities, and a safe distance range, whereas it enhances capacity and guarantees operational safety. The following trains smoothly operate in coordination with the preceding train to maintain a safe separation distance, thereby preventing collisions between trains.</p>","PeriodicalId":50381,"journal":{"name":"IET Intelligent Transport Systems","volume":"19 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/itr2.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100602","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}

The aim was to enhance the prediction accuracy in identifying moving vehicles through the integration of scene-flow analysis into tracking. The research was motivated by the importance, in autonomous driving, of analysing the state exclusively of moving vehicles. We implemented a novel, synergistic, vision-based, and offline approach, named MoVe, combining spatial analysis of predicted scene-flows and temporal tracking, from sensor-fused input data. Regions of moving vehicles (post background refinement) were obtained via instance segmentation, and each instance mapped to the corresponding (original) scene flows.

The proposed fusion segmentation model produced an mIoU of 82.29% for cars, outperforming YOLOv7 which relies solely on visual features. Notably, we observed a complementary dynamic between scene-flow analysis and tracking. Scene-flow analysis was generally effective in identifying fast moving vehicles, even under occlusions or truncations caused by other vehicles or infrastructure elements, while tracking usually excelled in identifying comparatively slow moving vehicles. Thus, the study demonstrated the viability of our proposed architecture to improve the detection of moving vehicles around an ego-vehicle.

Although previous research has advanced our understanding of travel patterns during abnormal conditions, knowledge remains limited regarding how urban travel changes spatially (e.g. by different spatial clusters) during extreme precipitation events. To address this research gap, this study aims to assesses how urban travel, by number of trips, changed in response to extreme precipitation events using time series clustering and discrete choice modelling. The study uses cell phone signalling-based mobility big data before, during, and after the perturbations, with the 2021 Zhengzhou floods as a case study. Moreover, the aggregated responses of urban travel were empirically defined in terms of the magnitude of trip reduction and time-to-recovery, i.e. travel resilience. The study identifies four distinct groups that exhibit comparable response and recovery patterns, which can be subject to the influence of factors associated with the built environment. The study reveals that areas with higher road network density are comparatively more vulnerable to the initial impact of extreme rainfall and flooding. Nevertheless, taking a long-term perspective, higher road network density contributes to faster recovery and more robust travel resilience. Moreover, home-based work trips are less sensitive to red rainfall warnings than home-based other trips and non-home-based trips. This study provides valuable implications for planners and policymakers to resist similar future events.</p>","PeriodicalId":50381,"journal":{"name":"IET Intelligent Transport Systems","volume":"19 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/itr2.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944569","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}
