РАНЖИРОВАНИЕ ТЕРРИТОРИИ ГОРОДА НА ОСНОВЕ РЕЗУЛЬТАТОВ РАСЧЕТНОГО МОНИТОРИНГА ЗАГРЯЗНЕНИЯ АТМОСФЕРНОГО ВОЗДУ-ХА СТАЦИОНАРНЫМИ ИСТОЧНИКАМИ

The article focuses on a method for ranking the city territory according to the level of atmospheric pollu-tion. Calculations of dispersion of emissions from stationary sources are performed, maximum one-time and average annual concentrations of harmful substances for the city of Nizhnekamsk, which is a large center of the petrochemical and oil refining industries, are determined. Analysis of peak short-term expo-sures is carried out on the basis of maximum concentrations expressed in terms of hygiene standards, reference concentrations for acute inhalation exposure and odor thresholds of substances. Long-term impact analysis is based on the Integrated Air Pollution Index. Based on the results of the calculation of these parameters, the zoning of the city'territory is carried out.

ОЦЕНКА ВЛИЯНИЯ АНТРОПОГЕННЫХ И ТЕХНОГЕННЫХ ФАКТОРОВ НА ЗАГРЯЗНЕННОСТЬ ПОЧВЕННОГО ПОКРОВА ГОРОДА

The aim of the study is to assess the ecological state of the territory of an industrial city based on moni-toring the soil cover. In the winter period, the study of the soil cover of the urbanized territory for the con-tent of sulfates, nitrates, chlorides was carried out, and the pH values were determined. Analysis of the spatial distributions of the studied substances in the soil cover in the area of influence of a large industrial center show the variation of the content of pollutants due to the impact of anthropogenic sources; there is an excess of the background concentration for all tested ingredients. In the course of the research, it has determined that it is advisable to use data on soil pollution in the study area as a means of control-ling the impact of anthropogenic sources on the environment.

Ambulance Locations in a Tiered Emergency Medical System in a City

This paper deals with optimizing the location of ambulance stations in a two-tiered emergency medical system in an urban environment. Several variants of station distribution are calculated by different mathematical programming models and are evaluated by a detailed computer simulation model. A new modification of the modular capacitated location model is proposed. Two ways of demand modelling are applied; namely, the aggregation of the ambient population and the aggregation of permanent residents at the street level. A case study of the city of Prešov, Slovakia is used to assess the models. The performance of the current and proposed sets of locations is evaluated using real historical data on ambulance trips. Computer simulation demonstrates that the modular capacitated location model, with the ambient population demand, significantly reduces the average response time to high-priority patients (by 79 s in the city and 62 s in the district) and increases the percentage of high-priority calls responded to within 8 min (by almost 4% in the city and 5% in the district). Our findings show that a significant improvement in the availability of the service can be achieved when ambulances are not accumulated at a few stations but rather spread over the city territory.

ВЫЯВЛЕНИЕ И КЛАССИФИКАЦИЯ ГРАДОСТРОИТЕЛЬНЫХ КОНФЛИКТОВ ПРИ ИСПОЛЬЗОВАНИИ ВОДНЫХ РЕСУРСОВ В Г. БЕЛГОРОДЕ

Sustainable development of the territory is impossible without balanced processes of anthropogenic human activity and rational use of natural resources. The problem of sufficiency and quality of water resources is relevant for the city of Belgorod. For 2021, the Belgorod region is limited by the resources of local surface and underground wastewater, with a fairly high level of municipal, agricultural and industrial consumers. The relevance of this work also lies in the increase in anthropogenic load on the natural framework, which entails a significant deterioration in the quality of surface and groundwater. In this regard, urban planning conflicts arise, which have an impact on the development of the city territory and the quality of the living environment. The research examines urban planning conflicts in the use of water resources in Belgorod. The causes of urban planning conflicts in relation to riverine territories and available water resources have been identified. The identified regulatory, property, land use, transport, social and functional urban planning conflicts are classified according to the hierarchical level, by duration, by the method of occurrence, by type of location, by the nature of manifestation. The introduction of water-saving design into the urban planning practice of the city of Belgorod is justified.

LIFESTYLE, ARCHITECTURE AND QUALITY OF THE URBAN ENVIRONMENT

The study reveals the aspects that defi ne the concept of “lifestyle”, including the main categories: standard of living, lifestyle, quality of life and lifestyle. Insuffi cient knowledge of the mutual infl uence of people’s “lifestyle” on the typological structure of apartments and residential buildings, on the quality of the urban environment is emphasized. The infl uence of the level of urbanization of the city territory on the characteristics of the “urban lifestyle” is considered. Problematic issues are raised related to the debate on the relationship between building density and comfort and the quality index of the living environment. The main directions of fundamental research in the fi eld of architecture, aimed at the development of new types of buildings, are touched upon. The emphasis is made on the methods of using high-rise buildings for the humanization of the urban environment and the formation of a modern “compact city”.

THE INFLUENCE OF MIGRATION PROCESSES ON THE FORMATION OF THE URBAN OBJECT STRUCTURE

In the article was found that the planned location of new or expansion of existing production clearly coincided with the movement of certain segments of the population to these regions for employment, examining and analyzing the problems of migration of the population of the former USSR.
 The researches of the Russian town-planners Bocharov Y.P., Belousov V.M., Vladimirov V.V., Maloyan G.A., Lezhava I.G. and other are devoted the problems of development of the theory of settlement with loss of planning component in development of systems of settlement and general plans of cities in new market (social and economic) conditions.
 Leading domestic urban planners have devoted their research to the problems of the development of the theory of settlement in Ukraine, the system of settlement and the development of master plans in modern market conditions (1992-2014). Some of them are Filvarov G.K., Yezhov V.I., Demin M.M., Lavrik G.I., Repin V.M., Timokhin V.O., Shkodovsky Y.M., Rudnitsky A .М. and other.
 The article presents the stages of formation of production relations, social, economic, architectural and spatial evolution under the pressure of migration processes, based on the analysis and research:
 
 The formation of the labor market (places of employment) in the development of industry, transport links and resettlement (early nineteenth - early twentieth century).
 Urbanization of cities in the early twentieth century due to migrations (free labor) from near and far agglomerations.
 Urbanization of the late twentieth century due to the release of labor (the collapse of the collective and state farm system).
 
 Under the pressure of migration and transport processes the compositional and planning spatial structure of the city is determined by the following aspects: the hierarchy of the city in the general network of settlements; the level of the city's public transport network; mobility of city residents; location of attractive objects for migrants in the city planning structure; socio-demographic characteristics of residents. Territories of cities with developed production are becoming the poles of industrial industry with the latest technologies, as well as centers of business.

Assessment of the noise level on arterial streets depending on traffic flow indicators

The intensity of traffic flows increases every year and intensifies its impact significantly on urban territory's ecologic situation and natural environment. In Ukrainian cities, the growth of noise pollution is quite a topical problem as it has a significant impact on the environment because of the increase in car numbers. Traffic flow intensity and densification of the built-up area cause the increase of the noise level. As analytical methods of calculation of determination of traffic noise level have several disadvantages, then for assessing the level of noise on arterial streets of Lviv city, research is carried out with consideration of traffic flow indicators. One of the critical criteria that have an impact on noise pollution in the urban environment is traffic flow composition. Conducted research indicates that the speed of traffic flow creates significant noise pollution, especially on those streets where cobblestone is a road pavement. Freight and passenger transport that moves along arterial streets causes the increase of noise level and increases its impact on the city territory. On sections of arterial streets in peak periods of the day with high values of volume-capacity ratio and general share of freight and public transport of more than 30% in a flow, the noise exceeds the acceptable norms and has a harmful impact on the environment. That is why it is necessary to assess noise pollution and the development of protection measures from noise during the planning and construction of some urban regions or residential areas. It is established that to lower the noise level on streets, it is necessary to consider existing intersections of arterial streets and the regime of movement on them. To lower transport noise, it is necessary to distribute freight and transit transport by city streets more rationally, use qualitative public transport, and limit the maximal speed regime on city streets. Further research on the road network will provide an opportunity to assess the noise level distribution of traffic flows in Lviv city. It will help to determine the problem places and propose methods of combating traffic noise.

ECOLOGICAL AND GEOCHEMICAL SPECIFICS OF SOIL AND PLANT COVERING OF URBAN LANDSCAPES (IN THE TOWN OF BROVARY AS AN EXAMPLE)

The results of the pollutants content research in urbanized landscapes soils of Ukraine (on the example of Brovary city, Kyiv region) were shown. The total and mobile contents data of chemical elements (Ni, Co, Zn, V, Pb, Cr, Cu) were obtained and analyzed using the methods of landscape-geochemical studies, analytical and statistical methods. The dependences of the vegetation resistance in cities to the level of soil cover contamination and the degree of heavy metals income have been established. The geochemical characteristics (such as the value of the accumulation coefficients; concentration of soil and vegetation cover; index of biogeochemical activity of the species within Brovary city) were analyzed.&#x0D; Throughout most of the city territory, the level of soil contamination is above average. Soils are characterized by the following association of heavy metals: Cu&gt; Pb&gt; Zn&gt; Co&gt; Cr&gt; V&gt; Mo&gt; Mn&gt; Ni. The dominant association is distributed heterogeneous throughout the city, forming geochemical anomalies depending on the source of contamination. The maximum technogenic load was recorded in urban soils areas within zones of transport infrastructure, production and communal-warehouse facilities.Woody vegetation is the most actively absorbed copper, manganese from the soil, and the least intensively absorbed chromium, vanadium and nickel. The biogeochemical activity coefficient of the research species is the following: Acer platanoides - 7,26, Betula pendula Roth. - 7,07, and Populus deltoides - 7,05, Pínus sylvestris - 1.32 and Alnus incana - 3.37. The biological absorption coefficients of manganese and copper are high because these metals have the ability to form strong complexes with organic matter. Biological absorption coefficients of vanadium and chromium is low for the researched plant species because these chemical elements are immobile in soils.&#x0D; For the city of Brovary, the presence of polyelemental contamination of soil and vegetation has been established. According to the indicators of the gross content of VM, the main pollutants are Cu, Zn, Pb and Mn. Concentrations of gross and mobile forms of VM exceed background values ​​and maximum concentration limits in 17-28 times. The maximum of man-caused load was recorded in the urban soils of the transport infrastructure zone and the zone of production and communal-warehouse facilities.&#x0D; Regularities of formation of elemental composition of plants of urban areas undergo significant changes in comparison with natural conditions, which is due to the strengthening of the role of foliar absorption of pollutants from the air and their high content in soils. The greatest ability to bioaccumulate has a male thyroid (Dryopteris filix-mas Schott) and birch (Convolvulus arvensis). The highest coefficient of biogeochemical activity of the studied species is Acer platanoides - 7.26, hanging birch (Betula pendula Roth.) - 7.07 and Canadian poplar (Populus deltoides) - 7.05, the lowest - Scots pine (Pínus sylvеstris ) - 1.32 and gray alder (Alnus incana) - 3.37. Weakly and very weakly, most of the studied plant species capture vanadium and chromium, which are relatively sedentary in the soil.&#x0D; Further research is needed to analyze the physicochemical parameters of soils, the coefficients of transition of metals to plants relative to their content in organic and mobile form in order to establish the relationships that characterize the process of translocation of chemical elements.&#x0D; Keywords: landscape-geochemical conditions, heavy metals, soils, vegetation.

Theoretical aspects of the calculation the main design parameters of the electric bird repeller

The problem of scaring away birds was born in ancient times and remains relevant to this day. Birds tend to places where they are comfortable and stay there. Therefore, to achieve maximum effect, new and effective designs of electric bird repellers are needed. Currently, the territories of cities and their outskirts serve as a habitat not only for people and domestic animals, they are also a habitat for numerous species of wild birds. In the settlements and in their vicinity, a specific fauna of birds has formed. Its main features are a limited number of species and a large number of individuals. This is due to the fact that few bird species were able to adapt to the specific living conditions in the city. However, those who were able to adapt found in the city a favorable environment for rapid and mass reproduction. The number of synanthropic birds in large cities reaches tens and hundreds of thousands of individuals [2]. Synanthropic birds are wild birds that constantly live in the vicinity of humans or have found favorable nesting conditions in the territory of settlements and their environs. Many spheres of life of synanthropic birds are directly related to human activities, since the food of synanthropic birds is anthropogenic in nature, because their diet usually includes seeds of cultivated plants and all kinds of food waste [3]. In each region, different species of birds prevail, but there are patterns that are characteristic of the entire territory of Russia. Almost everywhere, the main representatives of the synanthropic are house sparrows and doves. In the central part of the country, you can safely add the hooded crow to this list. When moving towards the west, the number of crows decreases markedly.

ASSESSMENT OF THE IMPACT OF VEHICLE EMISSIONS ON THE ATMOSPHERE OF THE CITY OF VORONEZH AND THEIR MINIMIZATION

The paper considers the emissions of pollutants from road transport, in the total air pollution they make up 70 % on the example of a particular metropolis. The highway is considered as a linear source consisting of single point sources of pollution. Special attention is paid to suspended fine particles in the solid phase. It is determined that when assessing the level of environmental pollution, it is important to take into account not only the total number of vehicles, but also the ratio of cars of different categories, since they, having different emission factors, supply unequal volumes (mass) exhaust gas components. The variability of the traffic flow density on the streets of six administrative districts of Voronezh and the complexity of zoning the city territory because of three-year monitoring were established. It is proposed to place accounting points on streets that differ in their status in the general transport network of the city in order to obtain reliable data during the monitoring period [11]. The simulation of diffusion movements and migrations of solid-phase air pollutants of roadside territories is carried out. The model of diffusive displacements and migrations of heavy metals is considered in relation only to passive contaminants. The choice is implemented and the method of studying the level of dustiness of motor transport roads is recommended, which allows fixing dust particles from 0.1 microns to 250 microns in the air. An algorithm of an improved system for monitoring the content of fine dust in the atmosphere of a residential zone is proposed. [16]. To minimize the emission of suspended substances, a two-stage emission purification system consisting of a gas-liquid absorber and a catalytic adsorber is proposed.

Monitoring of the condition and use of land in settlements (on the example of the city of Tchaikovsky, Perm Krai)

The paper presents a methodology for monitoring the lands of settlements, analyzes the state of the lands of the city of Tchaikovsky by qualitative and quantitative indicators, evaluates the assessment of the actual state of the lands of the city of Tchaikovsky, and develops a set of measures aimed at the rational use of the lands of the city of Tchaikovsky. The calculations carried out on the level of development and intensity of use of the territory over the past 10 years have allowed us to establish that, over the past 7 years, this indicator has hardly changed in the territory of the city of Tchaikovsky, only 1%. According to the results of a qualitative assessment of the state of the land, it was noted that the humus content in the soils is very low: no more than 3%, in heavy varieties, less than 2% - in light ones. Due to the small capacity of the humus horizon, it is completely involved in the arable layer, so it is reduced on the slopes as a result of water erosion. 35.5% of farmlands with a predominance of a weak degree of water erosion are subject to erosion processes. As a result of the assessment of damage from the manifestation of degradation processes, the amount of 60595 thousand rubles was established. As a result of the landscape and ecological zoning of the city territory, violations of the land use regimes within the boundaries of the established zones were established. Based on the comprehensive analysis, measures have been developed aimed at reducing the negative impact of enterprises and degradation processes. A set of measures to stabilize the state of the lands of the studied settlements is proposed.

Urban soils: the results of the study of the territory of the city of Ekaterinburg

In this article, we will consider the interesting, in our opinion, presented data of practitioners and scientists in terms of studying the formation and composition of urban soils, which is the most objective and stable indicator of man-made pollution, it clearly reflects the spread of pollutants and their actual distribution in the components of the urban environment. In this article, we have only shown the results of the analysis of the soils of g.For the period of the last 10 years, it is possible that for conclusions about the impact of the existing situation of the city territory on the entire environment, a more complete study of not only the chemical composition of soils, but also the impact of the economic mechanism of land management on the state of the city is necessary, the authors have not yet set themselves such a task.

ON IMPROVEMENT OF ENVIRONMENTAL INDICATORS OF THE KHARKIV MOTORWAY SECTION

Nowadays, on the territory of large cities, there is an increase in emissions of harmful substances into the atmosphere. The reasons for this are manifold: violation of design technological regimes, outdated equipment, an increase in the volume of road transport. The constantly growing intensity of traffic flows is annually accompanied by an increase in the anthropogenic load on the population of modern cities. With the increase in the number of vehicles on the streets of large cities, the world community has identified noise as one of the main factors that worsen the standard of living of people. To assess the noise pollution of the environment by road transport, a typical area of the urban area in the Kharkiv micro district was chosen. The study consisted of four main stages: Stage I – assessment of the road condition and environmental situation in the courtyards of the micro district; Stage II – assessment of acoustic pollution of the main area; Stage III – assessment of the concentration of pollutants; Stage IV – measures to reduce the level of environmental hazard. The study revealed that residential areas around Gagarin Avenue are prone to high noise levels and high concentrations of pollutants in the air. So, Gagarin Avenue is in the zone of acoustic discomfort (noise level 80 dBA), which exceeds the permissible noise level, while the degree of man-made impact on the environment during road operation is 1000 UAH / hour for every 100 people. Based on the results of calculations of the concentrations of pollutants from vehicles along Gagarin Avenue, it was found that for almost all substances their concentrations exceed the MPC by more than 3 times. Analysis of the experience of European countries in the use of noise protection screens with integrated solar panels allowed us to propose a model of noise protection barrier with integrated solar panels, which can be used to protect the urban environment from noise, sound waves and exhaust chemicals. gases from internal combustion engines. It has been established that the placement of a combined noise protection screen will reduce the noise level by about 8–15 dBA. Noise load maps were built in the main area before and after the implementation of the environmental measure. The results of the study will make it possible to introduce administrative and legislative measures to ensure regulatory noise levels for residential areas adjacent to highways and environmental safety when organizing traffic on the streets of large cities.

THE FEATURES OF FORMATION OF SUBSTANTIVE CHARACTERISTICS OF TERRITORIES IN THE FIELD OF COMPOSITIONAL INFLUENCE OF THE MONUMENT OF ETERNAL GLORY IN DNIPRO

Abstract. Problem statement. Today there is an active development of the coastal area along the Victoryembankment in the city of Dnipro. The proposed and those that have already been implemented provoke contradictoryresponses from ordinary citizens and professionals. Several project proposals have been implemented on this topic, aswell as a lot of material in the media and on social networks. There are scientifically sound proposals for theengineering of the coastal area. Purpose of the article. Show the stages of development of territories in the field ofcontent and compositional influence of the Eternal Glory Monument; their positive and negative sides. The main part.The general plans of the city and its fragments (1786; 1792; 1913; 1933; 1948) are considered. For the first two hundredyears of the city's existence, the Dnieper had an associative relationship between the city territory and the river. For thefirst time the task of connecting the river and the city was declared in the master plan of 1933. The next step in solvingthis problem in this direction was taken in the postwar master plans. The most striking of these efforts was the proposalto extend the main avenue of the city in a south-easterly direction with access to the edge of the central hill. It proposesthe formation of a memorial square at the northeastern end of the avenue, which is in contact with the valley of theDnieper River. The milestone is the creation of the Eternal Glory Monument. A full-fledged structure of an importanturban planning node of the city has been formed. This area of the avenue received a memorial and educational content.In world experience, there are few analogues of such a bright, organic combination of compositional and spatialcharacteristics of the territory and its meaning. Conclusion. Now there is an active architectural and town-planningactivity on the coastal territory is located on an axis of the main Avenue of the city. The most important factor thatshould have a significant impact on the nature of the processes that have developed to our time − the substantivefeatures of the compositional and spatial characteristics of Dmitry Yavornytsky Avenue. In turn, the means ofarchitecture must be found and implemented solutions that will not only give impetus to the development of what hasalready been created, but also logically complete the process of forming the most important urban node of the city.

Mobility as a crucial factor of spatial development in Function urban areas - Case study of Kosice region

The majority of the population of Slovakia - 53.35% live in 141 cities, with a density of 398.27 inhabitants/km2 which, however, occupy an area of only 14.9% of the total territory of the republic. In 2749 villages occupying 85.1% of its territory, 46.65% of the population lives at a density of 60.98 inhabitants/km2. In the last century, there was a significant migration of the village population in Slovakia to work in the cities. In the Slovak Republic, there are 325.8 dwellings per 1000 inhabitants, this indicator in the original states of the European Union ranges from 390 to 500 dwellings per 1000 inhabitants. The current shortage of flats in Slovakia has also become a political agenda; the current government has to build 25,000 flats a year in the program. The biggest obstacle to the housing construction program is the lack of suitable building plots. It is not possible to find enough plots only in the territory of cities, it will be necessary to organically involve municipalities in the vicinity – I functional urban areas of economically prosperous cities/regional centres in the preparation of suitable building plots and related infrastructure. The development of municipalities so far, as well as the preparation of building plots for housing construction, which relies on the "market will solve it" model, has not proved successful. Developers in the pursuit of financial profit have focused on the production of as many apartments as possible in the vicinity of economically prosperous cities without building the necessary infrastructure. Thus, new "Satellite Cities" were created, with a deficient transport connection to the dominant city. Based on the research made, we concluded that living in a village for workers working in the city requires quick transport between home and work. So effective mobility is a priority but also a necessary condition for young families to decide where to live. Article summarizing research dealing with the challenge mentioned above and offers a case study from Slovakia especially from FUA of regional centre Košice. Case study including the proposal for the mobility model for specific villages in FUA of Košice.

Transformation by Method of Sanation – Unregulated Residential Settlements of Sarajevo

In the second half of the 20th century, the industrialisation and deagrarization of Bosnia and Herzegovina had a strong impact on the dynamics of urban development and economic growth of the post-war Sarajevo, which intensified immigration from its relatively underdeveloped regional environment. This was accompanied by accelerated housing construction, and it encouraged the spatial expansion of the city. Planning guidelines were set by the city administration and were based on the long-term development plans. They identified the disposition of urban functions necessary for housing, work, recreation and traffic, and the policy of building multi-residential buildings was aimed general social interest. At the same time, the planning activities neglected the actual socio-economic status of immigrants who had lesser opportunities for housing through the social distribution system of apartments, began the process of self-organized unregulated settlement construction with single-family houses on the city's slopes. This began an era of two parallel but controversial actions within town space: planned and unregulated housing construction. Spontaneous possession of the city's territory with unregulated construction today is characterised by: complex property-legal relations, high degree of construction, absence of public space, pedestrian communications and service functions, low quality of the infrastructure network, and that settlements are formed on unstable terrains and on active landslides. Since the consequences of the complexity of the situation cannot be addressed through radical urban transformation, we see an alternative in the idea of partial spatial interventions – transformation by method of sanation. Starting with the thesis that construction is always deeply connected to society's understanding of the function of space and the place of man in it, we have opened up a central question, and searching for answers is the basic goal of this paper: Is it possible to solve problems accumulated by decades within Sarajevo's unregulated residential settlements through means of transformation by method of sanation? Or: Can partial spatial interventions improve the overall quality of individual and social life? For the purpose of finding answers, we conducted an analysis of the causes of the formation and genesis of these settlements, as well as a series of problems produced by the accumulation of separate spatial interventions without elementary professional guidance. The results of this analysis showed that the answer to the questions asked can be positive, by establishing a critical relationship with the potential of the space of specific settlement sites, in terms of the degree of functional usability, correlation with utilities and user interactions with the environments they inhabit. We have concluded that it is precisely the potential of individual sites, by logically applying the transformation by method of sanation, will enable dual achievement – the merging the solution within the technical and structural aspect of potential landslides with the articulation of the public on new pedestrian communications. Also, it has been shown that the application of this method enables the typification of technical solutions, functions, contents, activities, urban design, and even the public itself. And this means that the conclusions on the characteristics of individual Sarajevo unregulated residential settlements, endangered by landslides, can offer general guidelines for design concepts, within them, an overall improvement of individual and social life.

Features of the distribution of molecular hydrogen in groundwater in various geological and tectonic conditions of Uzbekistan

As a result of generalization and analysis of previously performed work on the determination of hydrogen on the day surface, a picture of the distribution of hydrogen concentration in the aeration zone was obtained. The increased concentration of hydrogen on the day surface and in the aeration, zone is associated with the most favourable conditions for the transit of fluids from the folded Palaeozoic basement to the surface cover (upper part of the Earth’s crust). These zones are zones of active fluid conductivity, which leads to a high concentration of hydrogen on the day surface. Intense linear anomalies are confined to the zone of intersection of the Tuzkoy-Rometan transverse fault with the Bukhara-Gissar regional fault, with which seismic events are associated (epicentres Gazli earthquakes occurred 08.04.1976, 17.05.1976 and 19.03.1984). Analysis of long-term observations of gas composition on an example of molecular hydrogen in groundwater southwestern part Karzhantaus fault, covering the territory of Tashkent city and its surroundings, obtained hydrogen concentration distribution pattern area. A different concentration of hydrogen in the fault zone was revealed, associated with the heterogeneity of the geological and structural structure.

MODEL OF NITROGEN OXIDE POLLUTION OF THE CITY MAINS

To manage the quality of atmospheric air in the city, it is of great importance to study the formation of extremely high atmospheric pollution. The preliminary assessment of atmospheric air pollution allows to determine the contribution of road transport emission sources, with the help of which it is possible to simulate a specific situation and to give predictive assessments of the state of atmospheric air pollution,&#x0D; as well as to determine the ways to improve the environmental characteristics of road transport, develop the city road network and other factors. The transport model of the city is one of the tools for strategic transport planning that allows for the justification and adoption of effective and responsible design decisions in the field of transport and infrastructure.&#x0D; The following data analysis on the available sources of atmospheric air pollution of the city mains has been performed: an assessment of the road transport intensity, an assessment of the amount of nitrogen oxides emissions, an assessment of the level of nitrogen oxides in the atmospheric air. Measurements have shown that the average concentrations of nitrogen oxides in places of intense anthropogenic load –the crossroads of city mains – are dozens of times higher than the maximum permissible concentration. Nearby the city mains and crossroads, the maximum concentrations of pollutants are formed at low wind speeds with wind directions at an angle close to 45° to the main areas.&#x0D; On the basis of the calculations, the following model of nitrogen oxide pollution of the city mains was obtained – the dependence of the concentration of nitrogen oxides on the road transport intensity can be a criterion for zoning the city territory according to the degree of atmospheric air pollution.
