TRANSPORT SYSTEMS

Abstract

The new concept of automotive transport development involves the advancement of power systems with a low carbon footprint, which comprise innovative components and assemblies such as electrochemical hydrogen generators, lithium-ion rechargeable energy storage and accumulation systems, various electrical components with voltages exceeding 400 V, and hydrogen storage systems operating at pressures from 350 atmospheres. Although such vehicles possess enhanced safety levels, they require specific approaches in various situations. With the proliferation of alternative energy vehicles, the necessity for their marking has emerged for various purposes, all of which are directly or indirectly related to improving safety during operation, maintenance, and repair, as well as during traffic accident response operations. Various methods of external identification and marking of vehicles exist worldwide, which have been successfully implemented and applied. This article presents an analysis of marking systems and their application purposes, followed by conclusions containing recommendations for implementation on alternative energy vehicles. The regulatory framework that provides the basis and methodology for such application is also examined. Portions of the marking may contain both information about design features and references to emergency response instructions for specific vehicle models.

Abstract

One of the most promising sectors within the service industry is the courier delivery sector. Delivery services provided by couriers using electric bicycles and personal mobility devices have gained particular popularity. In their efforts to deliver orders within the established timeframe, couriers frequently violate traffic regulations and pose safety threats to both vehicular traffic and pedestrians. Consequently, the object of this research comprises the social relations that emerge in the process of ensuring the safety of courier activities and courier company operations.

Abstract

This article initiates a series of publications on research conducted at the National Research University «Moscow Power Engineering Institute» oncerning charging infrastructure for electric transport (ET) in large cities and metropolitan areas. Primary attention is focused on examining the principles of constructing large-scale electric charging complexes (ECC) with dynamic power distribution between charging stations, enabling efficient service for electric vehicles (EV) of various types and power requirements: passenger cars, minibuses, electric buses, electric boats, and others. The study investigates possible charging structure configurations for ET in the development of high-capacity ECC installations (electric bus depots, charging areas for urban electric taxis, charging stations for electric boats and river trams) considering Moscow’s energy infrastructure. The conclusion emphasizes the promising prospects for implementing high-power electric charging complexes with common direct current bus systems.

Abstract

The article presents the results of a previously developed program [21, 22] for conducting field studies on the influence of vibration on buildings and structures arising from complex dynamic effects of surface and underground urban transport. The current regulatory framework in the field of transport vibration is examined, and the available practical results of vibration influence from three types of transport from each individual source of impact (tram, bus, metro) and with complex vibration effects (simultaneous) are analyzed. A pattern has been identified in the analysis of complex dynamic effects for predicting future events regarding crack development in buildings located in close proximity to sources of technogenic impact. The sources of vibrational impact are metro cars, trams, and buses moving in close proximity to buildings. Specialized equipment including a noise and vibration analyzer, recorder, and vibration tester was selected for vibration measurements.

To select the field site and conduct the experiment, an analysis of traffic load on surface and underground transport routes in Moscow was performed. Three of the most heavily loaded areas were selected for simultaneous vibration measurements from metro, tram, and automobile transport along Krasnoprudnaya, Paveletskaya, and Baumanskaya streets.

Abstract

Steel foundations are widely used in various sectors of industry and construction, including energy, telecommunications, and transportation infrastructure. One of the least studied external impacts is «rapid loading», which occurs when there is a sharp increase in load, where the rate of increase exceeds the rate of stress redistribution in the soil but does not cause dynamic effects. This paper presents experimental results aimed at evaluating the interaction of individual steel foundations with their base under rapid loading from operational loads of various levels. The study reveals significant changes in the stress-strain state of the force interaction between the foundation and its base under this type of external impact.

Abstract

The article performs an assessment of metro tunnel vibrations caused by concentrated force movement using mathematical apparatus that includes the Fourier transform and generalized function theory. The founder of this theory is Doctor of Technical Sciences, Professor of Russian University of Transport E. N. Kurbatsky. An example of solving a particular case of the problem for determining deflections, velocity, and acceleration of tunnel lining in a typical running tunnel during the movement of three cars in Vietnam is presented. The first metro line Bến Thành — Suối Tiên in Ho Chi Minh City has a maximum static gross load of wheel pair on rails equal to 12 tons. It was revealed that Vietnamese standards in this field are still developing and rely on international experience (Russia, Japan, China) as the line was launched only in 2024. Recommendations are given to foreign contractors participating in construction.

Abstract

The article examines the potential applications of artificial intelligence (AI) technologies for enhancing the efficiency of expert review of goal-setting documents in research and development projects. The study analyzes existing methods of expert assessment and identifies their shortcomings, including high labor intensity, subjectivity, and significant time requirements. The authors propose an architecture for a Digital Intelligent Expert System (DIES) capable of automating key stages of the expert review process, including expert selection, document analysis, and conclusion formulation. Particular attention is given to the selection of AI methods, such as machine learning, natural language processing, and hybrid approaches, as well as their integration into existing expert review processes. The article is addressed to specialists in science management, experts, and developers of digital solutions.

Abstract

This article examines the assessment of perceived affordability of Moscow public transport among passengers. The evaluation is conducted using the Price Sensitivity Measurement method (PSM method) and the Perceived Demand Elasticity for Transport Services model (PDETS model), based on an online survey of 1 502 respondents. The analysis focused on the «Wallet» ticket option using the «Troika» card for single journeys. The results established that the acceptable price range spans 63-95 rubles. The current fare of 63 rubles is considered acceptable by 82 % of respondents. The PDETS model enabled assessment of changes in perceived price affordability of Moscow public transport resulting from the fare increase from 61 to 63 rubles. The evaluation demonstrated a 4% decrease in perceived affordability among passengers who frequently use public transport (six times per week or more).

Abstract

This research analyzes the structure and content of communications between Moscow's transport complex and its residents, with the aim of assessing user satisfaction levels. The communications encompass all aspects of user interaction with the transport system: route planning, obtaining schedule information, fare payment, feedback provision, notifications about transport service changes, incidents, and other related matters. The research object includes both digital communication channels (mobile applications, websites, social media platforms) and traditional channels (signage, announcements, information boards). Employing H. Lasswell's communication model and focus group methodology, the study examined the characteristics of information interaction among various user groups, transport organizations, and infrastructure elements. The research findings identified both strengths of the existing communication system and areas for improvement. The authors provide recommendations for optimizing communication strategies to enhance citizen satisfaction.
