This study analyzes road graph and road marking graph construction principles for high-precision digital maps and conventional digital maps, as well as potential vehicle trajectories for various map sections. A practical experiment demonstrates the feasibility of vehicle operation with an automated motion control system using mixed maps.

This study investigates chitosan application as a biosorption material to mitigate cyanobacterial blooms in water bodies, using the Nagatinskiy backwater of the Moskva River as a case study. The research addresses the critical environmental issue of aquatic eutrophication caused by excessive cyanobacterial proliferation, which degrades water quality and poses risks to waterway navigation. Algal blooms form flocculent and film-like accumulations on water surfaces, creating hazardous conditions for vessels by causing blockages and damage to ship mechanisms while complicating navigation and maneuvering. The proposed technology employs submerged chitosan modules manufactured from polymeric chitosan with high deacetylation degree (85%) to sorb phosphate ions, the primary nutrient source for cyanobacteria. Laboratory experiments demonstrate phosphate ion sorption efficiency of 73–87% at concentrations up to 500 μg/L, while field trials show a 57.9% reduction in phycocyanin pigment content, indicating significant cyanobacterial growth suppression. Toxicity assessment of spent modules reveals no adverse environmental effects, supporting this technology as an ecologically safe method for controlling algal blooms with potential secondary use of chitosan as fertilizer.

In the context of rapid motorization of modern cities, the problem of parking space deficit in residential zones has reached critical urgency. Despite the organization of specialized parking lots, courtyard areas remain under high pressure, leading to deterioration of urban environment quality. This study examines the relationship between occupancy levels of adjacent open parking lots and parking intensity in residential courtyards. Mathematical statistical methods, including linear correlation coefficients and Student’s t-test, reveal a statistically significant relationship between these parameters. Regression analysis yields empirical dependencies that enable quantitative assessment of parking lot occupancy based on relative courtyard occupancy, accounting for seasonal and weekly variations. The methodology and findings offer practical tools for optimizing parking infrastructure design and enhancing urban land use efficiency.

This study develops and validates a comprehensive testing methodology for innovative cladding materials: Quantum Ceramic metal-ceramic panels and Quantum PaRUS aluminum panels. The research evaluates their potential for transport construction applications to create aesthetically expressive, durable, and safe infrastructure environments. Laboratory testing confirms the materials’ superior physical, mechanical, and performance characteristics. The paper analyzes the completed new passenger terminal at Kazan Airport, where these materials harmonized the spatial environment and strengthened regional identity. The findings demonstrate their suitability for cladding transport infrastructure within integrated territorial development frameworks.

This study addresses the critical issue of ensuring seismic resistance of pile foundations for transport structures under soil liquefaction conditions. The analysis examines characteristic failure modes of conventional piles documented during major earthquakes and identifies a key deficiency in current regulatory documents: inadequate consideration of buckling risk for long piles under combined axial and lateral loads. The paper proposes piles with end or multiple enlarged bases as an effective solution. Through analytical modeling and numerical simulation in MIDAS GTS NX software, a comparative analysis demonstrates that pile groups with enlarged bases significantly enhance stability by redistributing and reducing bending moments, shifting maximum moment locations to zones more favorable for reinforcement placement, and decreasing overall settlement. The study formulates practical design recommendations, including requirements for pile embedment depth into stable soil layers and the necessity of establishing regulatory requirements for minimum pile diameter based on liquefaction zone depth.

The article discusses the need of society and business, including the transport and construction industries, for artificial intelligence (AI) tools that could fully and accurately perform complex tasks such as construction design. It is indicated that existing universal services based on Large Language Models (LLM) and highly specialized neural networks are not capable of handling this task in full. Artificial General Intelligence (AGI) is proposed as a probable solution. The article presents an overview of the current global understanding of what should be considered AGI, as well as an analysis of approaches proposed for its development. As a result, an original vision of an approach to the design and development of AGI based on functional mechanisms and structure of human intelligence is proposed.

Comfort represents a vital component of a human daily life. Urban residents spend considerable time commuting, making transport comfort a significant quality-of-life indicator. Comfort levels differ substantially between public and private transport for various reasons. The high convenience of private vehicles positions them as markers of socioeconomic status. Meanwhile, public transport comfort reflects the living standards of most urban residents. Enhancing passenger transport comfort holds equal importance for Russian citizens’ well-being as income growth.

The article examines the theoretical foundations of state participation in the modern market. State capital is considered as a specific form of state property functioning, focused on the increment of the aggregate social product. The increasing role of state capital as an instrument of national economic policy in the context of sanctions restrictions and global challenges is noted. The study reveals a growing integration of state and private capital, characterized by the interpenetration and mutual complementarity of public and private structures, resulting in increasingly blurred boundaries between the two. The specificity of state capital circulation is revealed through its two primary market functions: first, creating and maintaining conditions for private capital development; second, substituting for private capital upon its market withdrawal. Economic forms of partnership between the state and business are described.
