Research on Signal Timing Optimization and Traffic Efficiency Improvement at Highway Intersections under the Background of Intelligent Transportation

Runqiu Xu — 2026-04-07

This paper aims to enhance highway traffic efficiency by integrating a project focused on signal timing optimization at highway intersections. Supported by intelligent technologies, a reasonable optimization system is constructed. Practical application demonstrates that the signal timing optimization at highway intersections under this system yields significant results, substantially improving traffic efficiency. This provides a reference for subsequent signal timing optimization at highway intersections, aligning with the development needs of the intelligent transportation context.

Analysis of Reflection Crack Propagation and Its Influencing Factors in Asphalt Overlay on Old Cement Concrete Pavement Based on Finite Element Method

Li Xu — 2026-04-07

Reflective cracking is one of the primary early-stage distresses in asphalt overlays on existing cement concrete pavements (white-to-black resurfacing structures). To delve into its mechanical evolution mechanism, this study established a three-dimensional thermal-mechanical coupled numerical model using the finite element software ABAQUS and quantitatively analyzed the variations in the stress intensity factor (SIF) during crack propagation using the J-integral method. The study systematically investigated the influence of material modulus, structural layer thickness, and external loads (traffic and temperature) on the SIF. Sensitivity analysis results reveal that environmental temperature drops and vehicle overloading are the core drivers of reflective crack propagation, with significantly higher sensitivity than structural material properties. Increasing the thickness of the asphalt overlay generates a notable “bridging anti-cracking” effect, representing the most effective structural means to inhibit crack propagation. The research findings provide a theoretical basis for anti-cracking design and lifespan prediction in the rehabilitation of existing pavements.

The Application of Generative Artificial Intelligence in the Conceptual Design Phase of Green Buildings: A Bridge Between Theory and Practice

Yixin Peng — 2026-04-06

In the development of green buildings, the conceptual design phase determines the whole-life-cycle environmental performance and comprehensive benefits. However, traditional conceptual design methods face bottlenecks such as low efficiency and strong dependence. As a new type of digital tool, generative artificial intelligence (Generative AI) can promote the optimization of green building conceptual design and effectively improve building effects through its capabilities in data learning and goal-seeking. Starting from the conceptual design phase of green buildings, this paper analyzes the application value of generative artificial intelligence and proposes specific application and practice strategies, aiming to promote the in-depth development of green buildings and provide reference for the subsequent optimization of the green building conceptual design phase.

Research on the Transformation and Application of Intangible Cultural Heritage Visual Symbols in Modern Aesthetic Education

Xiaoyang Hu — 2026-04-06

As a concrete carrier of China’s outstanding traditional culture, intangible cultural heritage (ICH) visual symbols hold dual values of formal aesthetics and cultural expression, and serve as a core resource for constructing aesthetic education with regional characteristics. Hainan’s ICH items, such as Li brocade, Li pottery, and coconut carving, have fostered highly recognizable visual symbols like the Hercules pattern, frog pattern, and Gangong bird pattern. These symbols embody the craftsmanship wisdom and aesthetic ideals of the Li ethnic ancestors, providing unique resources for localized aesthetic education. Taking Hainan’s ICH as a case study, this paper addresses the existing problems in integrating ICH visual symbols into aesthetic education—including superficiality, formalism, and insufficient exploration of regional connotations. It defines the connotative scope and aesthetic education value of ICH visual symbols, analyzes their transformation logic and core principles, and ultimately offers a referential paradigm for local ICH-oriented aesthetic education.

Research on the Digital Conservation Technology Path for Historical Buildings from the Anti-Japanese War in Chongqing: Based on HBIM Framework and Multimodal Representation

Yue Yang — 2026-04-06

The historical buildings from the Anti-Japanese War in Chongqing serve as significant material witnesses to the urban memory of the rear area during the war and represent spatial texts interwoven with mountain architectural forms and wartime social life. Addressing issues such as diverse types, complex sites, scattered data, and the disconnection between Conservation and dissemination, this paper introduces technologies such as HBIM (Historical Building Information Modeling), AI semantic segmentation, knowledge graphs, digital twins, 3D Gaussian Splatting (3DGS), and WebXR. It proposes a digital Conservation pathway of “multi-source collection—Scan-to-HBIM—semantic enhancement—digital twin—multimodal dissemination”. Using digital models of historical buildings from the Anti-Japanese War in the Nanquan area as samples, the paper compares modeling and dissemination strategies across different Conservation levels, spatial scales, and utilization objectives, focusing on cases such as Tingquan Building, Kongyuan, Kong Lingjun’s Villa, Kongyuan Administrative Building, Lin Sen Bathhouse, Wei Lu, the President’s Residence, Bamboo Grove Villa, and the former site of the Research Department of the Central Political School. The study suggests that digital Conservation of historical buildings from the Anti-Japanese War in Chongqing should form a hierarchical system consisting of “archive layer—management layer—monitoring layer—dissemination layer”. High-precision collection and HBIM ensure authenticity, knowledge graphs and digital twins support continuous updates, and 3DGS, panoramic tours, and WebXR enhance public accessibility, serving Conservation decision-making, academic research, course instruction, and social sharing.

Interactive Relationship Between Light Environment and Crowd Flow in Metro Station Concourses

Mingwei Li — 2026-04-09

This study takes Chongqing Nanping Metro Station as the research object, focusing on the collaborative optimization of light environment and crowd flow in metro station concourses. It aims to reveal the two-way coupling interaction mechanism between light environment and crowd flow, solve the mismatch between traditional static lighting design and the spatiotemporal heterogeneity of dynamic passenger flow, and achieve the dual goals of improving light environment quality and optimizing crowd flow efficiency. By integrating high-precision spectral measurement, AI video analysis, physiological signal monitoring and multi-agent simulation technology, a coupling database containing 2400 light environment parameters and 2600 dynamic passenger flow data is constructed. Random forest algorithm is used to identify illuminance, lighting uniformity and color temperature as key influencing factors. A quantitative model relating these factors to passenger flow speed, dwell time and path deviation rate is established based on partial least squares regression. The social force model is innovatively improved by introducing a visual perception correction coefficient, and a multi-agent coupling model is developed for verification. The results show that the optimal parameter combination is illuminance of 150–250 lx, color temperature of 4000–4500 K, and uniformity U₀ ≥ 0.6, which can achieve a passenger comfort score of 4.1, a 15% increase in crowd flow speed, and a 25% reduction in lighting energy consumption. This study reveals the quantitative relationship between the two, providing important theoretical and methodological support for the refined design of metro spaces.
