TariqAmn's Innovative Road Safety Paradigm through Smart Technology

In response to escalating road safety challenges within Algeria, marked by rising traffic volumes and urban development, the "TariqAmn Algeria" initiative emerges as a groundbreaking approach in traffic management. This study delineates the development and deployment of this innovative system, which leverages intelligent traffic signs, LiDAR (Light Detection and Ranging, using laser light to measure distances) radar, and proactive brake control technologies, embedded within a robust traffic management framework. The system's dynamic adaptation to real-time traffic conditions and its enforcement of speed compliance are central to its design. Rigorous evaluations through SUMO (Simulation of Urban Mobility, a traffic simulation software) simulations and field tests in high-risk urban settings affirm its efficacy, demonstrating a 60% reduction in traffic incidents and a 50% reduction in speeding violations. By marrying local cultural insights with cutting-edge technology, "TariqAmn Algeria" not only enhances immediate road safety but also establishes a new paradigm in traffic management systems. The findings illuminate the significant scalability potential of the system, promising broader applications in enhancing road safety and adherence to traffic regulations across various regions, such as densely populated urban areas, high-traffic corridors, and accident-prone black spots. This initiative underscores the critical role of Intelligent Transportation Systems (ITS) in modern road safety strategies and sets a precedent for future technological advancements in the field.

Dwelling in unsustainability: tourism landscapes and modern roads in a remote part of Finland

The paper discusses tourism landscapes in a remote region of Finland where tourism, nature conservation and industrial land-use coexist in tension. It illustrates deep problems with the language of sustainability but suggests that applying the dwelling perspective (Ingold) to analysing tourism landscapes is an illuminating route to appreciating the unsustainable features of modern life generally, like technical infrastructures and the unsustainable practices they support. Through an analysis of how modern roads have shaped landscapes and livelihoods, the paper makes a case for the strengths of the dwelling perspective as long as sufficient emphasis is put on the wider economic and political conditions within which local life can be reproduced and (ecological) sustainability negotiated. It shows that nature tourism involves different ways of being unsustainable but that it also contributes, as policy makers over decades have hoped, to sustaining local livelihoods.

Research status and reflection of the mechanism of TCM manipulation in the treatment of cervical spondylosis under the background of multi-disciplinary intersection

The study of TCM manipulation's mechanism is the key scientific issue in the current manipulation research. It is the key and difficult point on the road of modernization and internationalization of Chinese orthopedics and traumatology. Meanwhile, it is also an important way to clarify systematically the scientific connotation of TCM manipulation. At present, our country is in an important period when multi-disciplinary intersection lead knowledge production, scientific innovation, and discipline development. The trend of cross-innovation between Chinese orthopedics and traumatology and other disciplines provides the carrier and method for the study of TCM manipulation's mechanism. Cervical spondylosis is the traditional dominant disease of Chinese orthopedics and traumatology. In recent years, many scholars have applied multi-disciplinary techniques and theories to explore the mechanism of TCM manipulation by focusing on the four dimensions of muscle, bone, blood vessel and nerve. The article takes the treatment of cervical spondylosis by TCM manipulation as the research entry point, and integrates the application status and implementation strategies of various techniques and theories under the background of multi-disciplinary intersection, which is conducive to the better combination, innovation and transformation of Chinese orthopedics and traumatology with other disciplines, and provides ideas and references for systematically clarifying the scientific connotation of TCM manipulation.

Stabilization of Loose Soils as Part of Sustainable Development of Road Infrastructure

In the context of growing demand for road infrastructure expansion, sustainability is of key importance. Enhancing road construction technology ensures efficient, durable transportation infrastructure, vital for economic growth. Responsible road construction, especially in areas of historical and environmental significance, is essential. Preserving ecosystems and local heritage in road planning protects valuable areas and supports regional sustainability. Rural roads, often in forested areas, should maintain natural aesthetics. Economic challenges require flexible, efficient roads. Many existing unpaved roads, especially in rural and forest environments, fail to meet increasing traffic and load of heavy agricultural and maintenance vehicles. Soil stabilization methods, discussed in various publications, offer sustainable solutions. Research on ecofriendly binding additives provides the opportunity to reduce cement consumption and CO2 emissions. Such innovations enhance road efficiency, reduce maintenance costs, and benefit the environment. Investing in modern road technologies mitigates climate change effects by reducing emissions and protecting ecosystems. Our research indicates that soil stabilization technologies significantly improve road strength and durability. Additives can increase compressive strength by over 50% with minimal cement content. Continued research into road quality and durability is vital for sustainable transport infrastructure development. The results presented in this paper were obtained after two periods of solidification: after 7 and 30 days, with three types of ads (ion-exchangeable, chemical, and polymeric) to cement. In all tests, compaction strength improved by at least 35% in samples with the lowest cement content.

Evaluation of Waste Ceramic Tiles, Reclaimed Asphalt Pavement and Recycle Concrete Aggregate as Pavement Sub-Base

The use of various reclaimed or recycled materials from ancient structures as a source of construction materials has become common in modern road and pavement engineering procedures due to the shortage of fresh natural aggregate supplies and rising processing prices. Waste ceramic tiles (WCT), reclaimed asphalt pavement (RAP), and recycled concrete aggregate (RCA) have all been used for a long time as aggregates in the construction of pavement. WCT, RAP, and RCA are all thoroughly analyzed in this paper, with a focus on their mechanical, environmental, and physical properties. To evaluate the load-bearing ability, drainage capabilities, and long-term durability of these substitute materials when applied as pavement sub-base, laboratory tests and performance analysis were carried out. Since different mixtures of these materials are created, the maximum California bearing ratio of 25.54% is found. By promoting the usage of recycled materials, eliminating waste, and lowering the carbon footprint associated with conventional construction processes, this initiative helps to sustainably build out transportation infrastructure.

Территориальные особенности оказания экстренной хирургической помощи сельскому населению (на примере Республики Северная Осетия-Алания).

The need to modernize healthcare dictates the study of healthcare organization at all levels. Special attention is paid to the territorial accessibility of medical care, including to the rural population, which differs in many specific features. The purpose of the study: to study the territorial features of providing emergency surgical care to the rural population, taking into account the number, density of population settlement, road infrastructure, and transport security in the Republic of North Ossetia-Alania. Research methods. Analytical and statistical research methods were used. The performance indicators of surgical departments of rural district hospitals for 2019–2022 have been studied. The analysis of the obtained data was carried out by the method of their structural description according to the selected main characteristics affecting territorial accessibility. Results. The Republic of Ossetia-Alania is characterized by high density and compactness of population settlement in rural areas. The creation of a modern transport infrastructure ensures the territorial accessibility of medical care. The republic has a fairly high level of provision with surgeons (2,53 per 10 thousand population) and a surgical bed fund (4,7 per 10 thousand population). However, there is a need to increase the efficiency of using the bed stock of rural surgical hospitals. The organization of surgical care in the republic in 2020–2021 was extremely negatively affected by the pandemic of coronavirus infection COVID‑19. The reduction of surgical and anesthesiological teams, beds and the volume of planned care due to the opening of additional infectious diseases hospitals has reduced the availability and quality of emergency surgical care. In rural district surgical departments, the bed function decreased from 283 days in 2019 to 243 days in 2020, and surgical activity up to 38,8%. In 2020–2021, planned medical care in the «surgery» profile has significantly decreased. The share of emergency hospitalizations increased to 79,7%. Negative trends in the growth of emergency hospitalization for surgical beds led to an increase in the hospital mortality rate compared to 2019 from 0,6% to 3,1% in 2021. The postoperative mortality rate has increased by more than 5 times. Our data correlate with similar trends of 33% increase in hospital mortality in the Russian Federation during the pandemic. Due to the creation of modern road transport infrastructure in the republic, high availability of surgical beds and surgeons, there is a potential to improve the quality indicators of rural surgical hospitals by improving the material and technical equipment and qualifications of surgical personnel.

Effects of mobile phone-related distraction on driving performance at roundabouts: Eye movements tracking perspective

Modern road infrastructures are complex networks featuring various elements such as roads, bridges, intersections, and roundabouts, with advanced control systems. Roundabouts have gained prominence as a safer alternative to traditional intersections promoting smoother traffic flow and fewer collisions by guiding traffic in one direction, encouraging reduced speed, and minimizing conflict points.This study investigated driver behavior within roundabouts, focusing on gaze behavior, particularly the left-side mirror and window, under mobile phone distraction conditions. In addition, the effects of roundabout specifications (i.e., number of lanes and size of the central island) and the drivers’ characteristics (i.e., driving experience) were examined.In total, 43 participants, aged 19–56 years including 30 males and 13 females, held a valid driving license, drove through a virtual simulated urban road containing four roundabouts, implemented in a static driving simulator, under baseline condition (no distraction) as well as mobile-induced distraction. Driving simulator data were collected and drivers’ gaze direction and fixation on nine areas of interest were captured with an eye tracker. Resultsshowed that experienced drivers exhibit a more fixation on the left-side mirror and window and were less distracted. Moreover, the road environment, i.e., the number of cars and the roundabout size, significantly influenced the drivers’ attention. As regards the driving performance, the number of infractions increased when the drivers diverted focus from the left side of the car. The outcomes of the present study might help to improve traffic safety at roundabouts.

Identification of Hybrid Polymer Material STERED and Basic Material Properties Used in Road Substructures or Pavements.

Modern road construction uses a large number of polymer-based materials. Material composition depends on their roles. Among the most important functions of road body materials is to transfer all loads safely to the subgrade. A thorough understanding of material properties in various climates is crucial for this purpose. In the automotive industry, polymer residues from recycling can be used to make innovative materials, such as STERED, a hybrid polymer composite. Drawing on the porous nature of this material, this paper investigates its mechanical behavior. For road construction, the compressive properties of the material are most important. The paper presents the results of a detailed analysis and experimental research of the STERED material from in-lab tests. Successful research will lead to the inclusion of the material in road body compositions with excellent retention properties, vibration damping, and potential in circular economy.

Modular Autonomous Vehicles’ Application in Public Transport Networks: Conceptual Analysis on Airport Connection

Increased efficiency and optimized operation of transport networks represent two of the main topics of interest when discussing modern road vehicle solutions. Taking steps towards more sustainable options, manufacturers of road vehicles are looking into advanced technologies that allow vehicles to run more efficiently and take advantage of all the available data on the road. When looking at public transportation applications, trends point in the direction of using varied types of vehicles that can carry people around. The intermodality of these types of vehicles represents the most optimized way of traveling, combining the fast and secure characteristics of airplanes and trains with the flexibility of last-mile options, such as taxis, buses, or trams. This paper discusses the aspects of implementing a modular autonomous vehicle (MAV) solution for the last-mile part of travel routes, connecting key points of a city, such as an airport or a train station, to other key locations in the city, such as the city center, important facilities, or marginal neighborhoods.

A Political Economy Analysis of Chinese Modernization

ABSTRACT The earliest form of modernization was capitalization, which Marx and Engels explained as occurring “on pain of extinction.” As the inherent contradictions of capitalism intensified, modernization showed a tendency to evolve in the direction of socialization, and two different and opposing models emerged: the Western European capitalist model and the Soviet socialist model. The modernization of the old China was destined to fail even while it was still on the starting line. It was not until the Chinese people, under the leadership of the Communist Party of China, overcame the Chiang Kai-shek regime, achieved victory in the New Democratic Revolution, and established the People’s Republic of China that the country’s progress along the road of Chinese modernization really began. For historical reasons, the new China was obliged to develop a novel approach to its modernization process. Reform and opening up enabled China to seize a new opportunity, and Chinese modernization began to accelerate. After socialism with Chinese characteristics entered a new era, modernization began to take flight. Chinese modernization provides humanity with a new choice as it confronts the modernization challenge. Although Chinese modernization reflects China’s specific national conditions and historical opportunities, it nevertheless has a definite world-historical significance.

The Irony of Cats in Literature: Comparison of the Works of I Am A Cat And A Tale of Cat City

In Natsume Soseki's "I Am A Cat", the cat's point of view is used to criticize the current bad situation of the society, and rely on the unbiased standpoint to see the bourgeoisie's oppression of others and the status quo of being rich and ungrateful, as well as the intellectuals led by Bitter Shamisen's anger and helplessness towards the current situation of the society. Lao She, who was also in the background of an era, wrote "A Tale of Cat City", which also used the image of cats. As a normal person, "I" observed the life of cat people and saw the disorder and panic in their lives to express my disappointment in the times and my confusion about the future path. The two writers, who are not connected with reality, coincidentally use the same imagery to reflect the social reality. Based on the two works, comparisons are used to understand the struggles and contributions of the Chinese people on the road of eastern modernization, and to reflect their character as the initiators of the modern countries of the East.

New methods to increasing efficiency for durability design of elastomeric bushings

The use of elastomers in modern road vehicles can solve many design conflicts in the development process. The prerequisite for this is a detailed calculability of the component properties, which are dependent on the geometric shape, the choice of material and the parameters of the manufacturing process. A robust method for calculating parameter-property relationships of elastomer bushings based on physical models and machine learning approaches allows these relationships to be calculated in the early phases of vehicle development. Viscoelastic material properties represent a major challenge for the durability design of elastomer components in load data acquisition. With the help of the modeling approaches developed here for load data analysis, load paths with elastomer bushings in the vehicle can be calculated much more accurately for high loads. A new method for experimental component validation is presented, which reduces the costly testing time for operational load tests by up to 85%. This method uses multi-axis block programs and achieves damage patterns comparable to the operational load test.

EFFECT OF DEICING AGENTS ON THE WATER STABILITY OF ASPHALT CONCRETE UNDER FREEZE-THAW CYCLES

Asphalt concrete pavement, as the main form of high-grade roads today, occupies an important place in modern road construction due to its advantages such as low noise level, ease of repair and short construction period. This road type is widely adopted worldwide and provides a reliable foundation for road networks in cities and villages. In cold regions, snowy weather tends to cause ice on the road surface, posing a serious safety hazard for vehicle travel. The problem of road accidents in winter is relevant both for regions with extremely cold climatic conditions and for the temperate continental climate that prevails almost throughout Ukraine. To solve this problem, deicing agents are widely used to improve the safety of road travel. The application of deicing agents effectively reduces the impact of snow and ice on roads and ensures the safe passage of vehicles in adverse weather conditions. However, while deicing agents play an important role in improving traffic flow, their widespread use has also brought some problems that should not be ignored. The chemicals in deicing agents may have adverse effects on pavement materials, especially on asphalt concrete roads. For studying the effect of deicing agents on asphalt concrete, this paper presents an experimental investigation of the effect of deicing agents on the water stability of asphalt concrete under the conditions of freeze-thaw cycle test. The impact of deicing agents and freeze-thaw cycles on asphalt concrete was investigated by evaluating the variation patterns of three key parameters: stability, residual stability and air void content. The experimental results showed that the stability and residual stability of asphalt concrete showed an overall decreasing trend with the increase of the number of freeze-thaw cycles, indicating that the asphalt concrete was damaged or degraded under the conditions of freeze-thaw cycles. The higher concentration of the deicer solution corresponded to the more pronounced changes in the test parameters, indicating a significant effect of the deicer on the asphalt concrete. At the end of 27 cycles, the average loss of stability, residual stability and void ratio were 29%, 22% and 73%, respectively. This indicates that the combined effect of freeze-thaw cycles and deicing agent is more significant for air void content.

URLA YARIMADASINDA ESKİ VE YENİ YOLLARIN KAVŞAĞI, BARBAROS OVASI

The Urla Peninsula stretches from the center of the western Anatolian coast to the Aegean Sea. Its fertile soils and maritime opportunities have made the peninsula economically and commercially important in every period. The route running on the east-west direction connects the peninsula to the Anatolian mainland. Both this route and the secondary roads connected to it converge and disperse in the Barbaros plain as required by geography. The high mountain masses that close the central part of the peninsula from north to south open up in the Barbaros plain. Before the construction of modern roads, the plain provided transportation facilities through its narrow passages. Archaeological data show that the plain was connected to the west by the Mataracı Gorge near the village of Birgi during the Early Bronze Age. The pottery finds observed on the commanding heights on both sides indicate the existence of an early derbent system. In Birgi, in the Hamamıkuyu area, there are the ruins of an accommodation place dating back to the 14th century. At the end of the 19th century, the Birgi connection lost its importance with the construction of a macadamized road passing through the southern part of the plain. The macadamized road coming from Urla follows the valley of Tatar Creek. Previously, Urla-plain connection was provided by the road passing through the Kavaklıdere valley to the north of it. Today's roads are also located on these two routes. Connecting the east-west main route, the plain is also the connection and distribution point for various secondary roads. These roads provide access to the southern sea via Ildırı (ancient Erythrai), Kıran (ancient Korakas/Korykos), Gülbahçe Bay and Zeytinler. Archaeological research provides data showing that the plain and its surroundings have been inhabited in various periods from the Neolithic period to the present day.

Site Formation Histories and Context of Human Occupations at the Paleolithic Site of La Ferrassie (Dordogne, France)

The Paleolithic site of La Ferrassie (Dordogne, France) has contributed significantly to the understanding of Middle and Upper Paleolithic technocomplexes, as well as Neanderthal skeletal morphology. Excavations at the site have spanned more than a century and uncovered rich archaeological assemblages associated with the Mousterian, Châtelperronian, Aurignacian and Gravettian technocomplexes. Renewed excavations exposed a sequence spanning both Middle and Upper Paleolithic occupations in the Western Sector and low-density Mousterian deposits and Châtelperronian in the Northern Sector. Here, we report on an extensive geoarchaeological study of deposits at the western end of the site to reconstruct and interpret both the depositional history of the sediments and associated human occupations in this poorly documented part of La Ferrassie. Our results point to the nature of the site as originally a karstic cave, with the Western Sector located in what would have been the cave’s mouth. The stratigraphic sequence comprises first fluvial deposition (Phase I) followed by soliflucted deposits and accretion cones that emanate from an elevated platform situated several meters above the modern road next to the site (Phase II) and, finally, spatially restricted channeling (Phase III). Most archaeological assemblages are associated with Phase II and reflect an interplay between occupations directly in this area and bones and artifacts sliding down the slope from the upper platform. Unlike in the Western Sector, in the Northern Sector — situated along the north wall and several meters inside the footprint of the cave — cold features dominate the entirety of the sequence; we interpret these as being linked to microenvironments specific to this location of the karst rather than to general (external) climatic conditions. Relevant is the identification of patterned ground formation in this area, which can be clearly linked to the “monticule” features first reported by Capitan and Peyrony and erroneously interpreted as anthropogenic in origin. Our geoarchaeological results point to a large and complex karst system, with distinct depositional sources and often locally independent sedimentary histories throughout its extent. These formation pathways have differently impacted the main occupation areas and resulted in distinct degrees of preservation of the archaeological assemblages throughout the different areas of the site.

HIGHLIGHTING OF FOCAL LANDSCAPES ON THE EXAMPLE OF VALLEY-RIVER LANDSCAPE-TECHNICAL SYSTEMS

River valleys are important in the structure of natural landscapes. They are the places of population concentration, ecological gutters and the landscape "framework" around which all other geocomplexes function. If the framework landscapes have been analyzed in detail by scientists, the focal landscapes are inflated beyond the attention of scientists.
 The purpose of the article is to analyze the structure of focal landscapes on the basis of the improved classification of anthropogenic landscapes by significance on the example of landscape-technical systems (LTchS) in the river valleys of the model region - the flat part of Right Bank Ukraine.
 Within the valley-river landscapes, the focal group includes road, mining, agricultural, and beligerative LTchS. Most modern road landscape technical systems belong to the category of "landscape technogenic systems". The destruction of man-made cover is associated with the excessive load on the road surface of motor vehicles, the weight of which often does not meet the established standards. As a result of mining and processing of minerals in river valleys, mining LTchS are formed. Active mining LTchS are formed by quarries, waste rock dumps and beneficiation or crushing and sorting plants and factories. The river valleys of the Right Bank of Ukraine are characterized by new anthropogenic types of areas that were formed after the extraction of minerals: areas of pit-peat wastelands and "rocky badlands". Valley-river agricultural LTchS are represented by water regulation and irrigation systems and vineyards. The lack of modernization and the use of outdated equipment and facilities do not allow the LTchS to fully function and produce the appropriate amount of crops. Beligerative landscape and man-made systems include complexes of defensive nodal structures "lines of defense" of the 20th century. Some critical remarks were made regarding the analysis of the structure of focal landscapes after the beginning of the full-scale invasion of the Russian Federation on the territory of Right Bank Ukraine. It was concluded that in the context of the study of modern anthropogenic landscapes of Ukraine, the study of focal valley-river landscape-technical systems will contribute to a better understanding of their structure and the development of ways of optimization.

Impact of Modern Vehicular Technologies and Emission Regulations on Improving Global Air Quality

Over the past few decades, criteria emissions such as carbon monoxide (CO), hydrocarbons (HCs), nitrogen oxides (NOx) and particulate matter (PM) from transportation have decreased significantly, thanks to stricter emission standards and the widespread adoption of cleaner technologies. While air quality is a complex problem that is not solely dependent on transportation emissions, it does play a significant role in both regional and global air quality levels. Emission standards such as Euro 1–6 in Europe, Corporate Average Fuel Economy (CAFE) regulations, Tier I—III standards in the US and the low emission vehicle (LEV) program in California have all played a huge role in bringing down transportation emissions and hence improving air quality overall. This article reviews the effect of emissions from transportation, primarily focusing on criteria emissions from road transport emissions and highlights the impact of some of the novel technological advances that have historically helped meet these strict emission norms. The review also notes how modern road engine vehicles emissions compare with national and international aviation and shipping and discusses some of the suggested Euro 7 emissions standards and their potential to improve air quality.

Moving Beyond a Strange Spectatorship

What can nonhuman road trauma, more commonly referred to as ‘roadkill’, teach us about ecological crises and human culpability? Incidents of nonhuman road trauma could be described as strange encounters, revealing the shared trauma of the nonhumans and humans involved while simultaneously highlighting the supposed inevitability of such events. I argue that the choice to check the rearview mirror – to exhibit attentiveness and care in self-reflection – is an act of radical correspondence with the more-than-human. Such correspondence functions as a kind of non-spoken letter to both nonhumans and other human drivers; a letter calling for acts of care and attentiveness that acknowledge the nonhuman experience, mourn losses, and possibly instigate radical change when it comes to how nonhuman road trauma is thought about now and hopefully avoided in future. In her work on the ‘Anthropocene noir’, Deborah Bird Rose speaks of ‘the Anthropocene parallel’ in which humans are spectators of the suffering of nonhumans, and also spectators of a suffering that is our own. Written as both an essay and a personal log of my own experiences with nonhuman road trauma, this work draws on Rose’s idea in an attempt to reconcile the concept of what I term a ‘strange spectatorship’, in which humans observe, are implicated in, and turn away from the phenomenon of nonhuman road trauma and what such trauma reveals about human-nonhuman relations, particularly for settler-colonial Australians. Reflecting on anecdotal experiences as well as the representation of roadkill in Australian literature, I explore the strangeness perceived in how settler-colonial Australians are both actors and spectators in nonhuman road trauma. I grapple with the idea of such trauma as a means of better understanding the settler-colonial impact on Australian natural environments, and the consequences for both humans and nonhumans if we do not better address the ethical and ecological consequences of our modern road infrastructure.

Special features of using neuronetwork technolo-ies to control the work processes of bulldozers with a gnss-intensifier

Abstract. Problem. The specificity of modern road construction works requires evaluation of the situation; forecast of the machine's normal operation and the development of emergency situations; synthesis and evaluation of possible actions of the operator and selection of the best ones. That is, there is a problem of effective support of the road car, whose solution is transferred to the intelligence of the car itself. A distinctive feature of intelligent systems is the ability to plan behaviour, adapt and learn. An intelligent system automatically changes the algorithms of its functioning and the structure in order to preserve or achieve an optimal state when external conditions change. The integration of algorithmic methods of controlling complex objects and methods of artificial intelligence is aimed at solving the tasks with uncertainty of the source information. The implementation of intelligent systems shows their prospects in the field of road construction works. Thus, optimization of road machine work processes, increasing the efficiency of road-construction machines (RCM) due to an intelligent control system is an urgent task. Studying the structure of the intelligent system of the road machine is relevant as well as developing a mathematical model of intelligent optimization of work processes based on the complex of readings of integrated GNSS sensors. Goal. The purpose of the research is to increase the efficiency of construction machines through their intellectualization, development of scientific algorithms for creating mathematical models of the working bodies of the RCM with SNS-intensifier of work processes of interaction with the soil environment. Methodology. In the paper the scientific methods of system analysis and decision-making theory for the structuring and synthesis of intelligent control systems are used; mathematical modeling methods for building and researching hydraulic and dynamic models of road vehicles; theories of automatic control under conditions of uncertainty; methods of object-oriented programming for simulation modeling of a road machine work process during operations. Results. For the first time, the methods of solving the problem of controlling the hydraulic drive of a road machine were offered, which, unlike traditional ones, take into account the execution of digging operations in conditions of a short decision-making time, which ensures the movement of the working body along an arbitrary trajectory in a short time with high accuracy. Originality. This paper is one of the first in Ukraine in which the scientific problem of increasing the efficiency of RCM at the interaction of working bodies with the soil environment in conditions of limited time for decision-making was formulated and solved. Practical value. Time of work is cut due to the reduced number of passes during soil development and increasing the productivity of RCM, which will have a positive effect on financial and labour costs, ensuring the possibility of continuous operation, which increases the productivity of RCM.
