LPDR systems are widely used in traffic monitoring, vehicle safety, vehicle-to-vehicle (V2V) communication, and reducing traffic accidents. Modern technologies like autonomous driving and traffic optimization require secure V2V communication. Vehicles can use the LPDR system to identify nearby vehicles to communicate safely. With the expansion of applications in daily life, LPDR is facing many challenges. From the simple static camera used at the parking lot entrance, the LPDR systems are currently used for dynamic recognition of vehicle license plates (LPs), which is very difficult due to camera movement, camera angle, and distance from the vehicles. Recognizing LPs from different countries using a single algorithm is challenging since different nations use different characters, and LPs comprise multiple lines. For instance, Arabic characters could be more challenging to recognize. This article provides a performance comparison of several real-time tested and simulated LPDR methods. An ideal LPDR system must eliminate the challenges arising from new applications. The LPDR system needs to be designed to work accurately on static/dynamic conditions to develop V2V communication. By categorizing existing well-known LPDR approaches into conventional and machine learning techniques, this review tried to clarify the importance of each type of method. This work aims to review LP detection, character segmentation, and character recognition algorithms and provide guidance on future trends in this area.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"13 3","pages":"Pages 974-1005"},"PeriodicalIF":9.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148545381","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}

However, certain regions reduce their own abatement efforts by free-riding on emission control measures implemented by neighboring areas, thereby undermining collaborative governance. This study develops a tripartite evolutionary game model to investigate the strategic dynamics of inter-regional emission control under heterogeneous traffic emission conditions. The model explores the evolutionary interactions and strategic adaptations of the three involved stakeholders. Numerical simulations further reveal dynamic changes in strategic choices and identify the key factors influencing the evolutionary process. The results reveal a dual-impact mechanism of regulatory intensity between two regions with heterogeneous traffic emission. Notably, regions with limited emission reduction capacity tend to engage in free-riding, capitalizing on the abatement efforts of neighboring areas. Although inter-regional emission interaction intensity does not directly influence regulatory strategies, higher levels of connectivity significantly increase the risk of free-riding behavior. The optimal evolutionarily stable strategy combination is “positive emission reduction, positive emission reduction, and moderate regulation”, indicating that moderate regulation can enhance collaborative control of inter-regional traffic emissions. The system exhibits multi-path and multi-stage evolutionary trajectories, with regulatory costs, subsidy rates, and regional emission reduction capacities emerging as key determinants.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"13 3","pages":"Pages 1051-1072"},"PeriodicalIF":9.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148545383","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}

Efficient allocation of parking slots is one of the key challenges faced by planners, especially when there is rapid growth in population. Most of the existing systems rely upon database and historical data for predicting future demands. However, the existing systems cannot account for changes in user behavior and real-world situations. This paper provides an automatic parking allocation system using ensemble learning and boosting methods. The system uses historical data as well as current data like location of users and availability of slots. Using an adaptive learning process, the system accurately predicts future demands and allocates slots accordingly. The system also eliminates the problem of wastage due to cancellation of reservation requests. With intelligent prediction and allocation capability, this parking allocation system provides efficient management of parking lots within digital urban landscapes. Performance assessment for the suggested framework is carried out through the use of standard performance measures, which illustrate the efficiency of the ensemble boosting algorithm. It can be observed from the experimental analysis that the combination of XGBoost and random forest results in a success rate of 98.8%, surpassing traditional techniques.

Addressing this challenge, a cooperative control method employing Monte-Carlo tree search (MCTS) is proposed for managing connected and automated vehicles (CAVs) at unsignalized intersection. A hierarchical framework for cooperative control of CAVs at unsignalized intersection is proposed, featuring centralized control and a space-time resource reservation mechanism. Acknowledging the presence of an unreliable V2X communication environment, the framework incorporates a time-out retransmission mechanism and a communication model based on a finite state machine. Subsequently, safety constraints are formulated to develop a trajectory planning method for CAVs using distributed MCTS. Accounting for both unbalanced traffic flow and an unreliable communication environment, four distinct test schemes are devised. Simulation tests are conducted by comparing the proposed method against the fixed time control (FTC) and actuated light control (ALC) strategies. Subsequently, a comparison is made with existing reinforcement learning methods. The results demonstrate that the proposed method consistently outperforms the other methods in all test cases. Particularly in scenarios of unbalanced traffic flow, the proposed method demonstrates a maximum average vehicle velocity 11.3 times and 5.1 times higher than that of the FTC and ALC, with an optimal vehicle density merely reaching 27.3% and 34.0% in comparison. Moreover, the average queue length consistently remains at zero. The proposed method reliably safeguards vehicle safety and efficiency across diverse unreliable communication environments, and is also capable of maintaining low vehicle delays across different traffic generation rates.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"13 2","pages":"Pages 540-555"},"PeriodicalIF":6.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147862972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of research reports on the instability of middle partition in deep shafts in water-rich strata. Based on the No. 1-1 shaft of the Tianshan Shengli Tunnel, currently the world’s longest operational expressway tunnel. Theoretical analysis and on-site measurement methods were adopted to conduct research on the instability and failure of middle partition in shafts. The results of both methods with numerical calculations were compared. It was indicated that the main cause of the instability of the middle partition is unbalanced water level on both sides. The larger the tunnel shaft diameter, the more unfavourable the bearing stability of the middle partition. The midspan displacements and bending moments of the middle partition increase with increasing water level difference load, and the values increase with higher axial loads. Furthermore, the midspan displacements and bending moments of the middle partition decrease with the increase of section parameters and increase with the increase of tunnel shaft diameter. However, they are not significantly affected by the change of concrete strength grade and reinforcement diameter. The water level difference between the one side of the middle partition led to a three-phase trend of “rapid growth, slow growth, decline” in middle partition displacement, and they all had the characteristics of the closer to the water level. The theoretical solution is better matched with the results of on-site measurements and numerical calculations, which can reflect the instability and failure of the middle partition. On-site measurements also confirmed the cause of the instability and failure of the middle partition. The axial load threshold for instability and failure is 0.03 MPa, and the water level difference load threshold is 10 kN/m.
