A significant role in ensuring comfortable living conditions in the urban environment is played by the competent organization of the transport and road complex, which is aimed at ensuring road safety, reducing the load on highways for car density and improving the efficiency of traffic in the city when performing planning and technological measures. At the same time, the current state of the city’s traffic flows as sources of increased chemical pollution of the air environment requires an increase in the distance from streets and roads to residential buildings. This distance should be normalized by chemical and physical indicators of the state of atmospheric air and should be taken into account when red lines are established. In this article we analyze: functional state of the city, road network, composition and intensity of traffic flows for Tyumen. The traffic flows of the city are concentrated mainly in the central part of it. A particularly critical situation is formed at the intersections of cargo-loaded main streets at the hours of maximum traffic intensity and on the main highways of the city. We substitute the provision of regulatory requirements for the chemical pollution level at a distance from the border of the carriageway to the border of residential buildings in order to achieve sustainable urban development.

The development of all spheres of human activity is associated with an increase in anthropogenic pressure on environment. Metropolitan areas and large cities are experiencing the greatest pressure. Both the development of new areas adjacent to built-up areas, as well as operating existing industrial and residential complexes suffer the influences. The article presents the results of a soil study conducted in the city of Novokuibyshevsk to determine the prospects for future growth of the city. Soil samples were taken throughout the city. When choosing the place of sampling, the locations of highways, industrial zones and residential buildings were taken into account. Soil testing was carried out to obtain data on the concentrations of heavy metals (lead, zinc, copper, cadmium, nickel, manganese, etc.), as well as sulfates and nitrates. The results were analyzed and contrasted with the standards and results of previous years.Based on the study of the current state of the soil, the authors assessed the degree of pollution of urban soils in an industrial city. In their study they proposed and developed measures to improve the condition of the soil, namely, analyzed the efficiency of using phytoremediation to reduce soil contamination in residential areas of the city.

<p><b>Development of technology and the rapid increase in population has led to tremendous growth in the population of China. Beijing the capital city has become significantly overcrowded due to a high number of residents.The traditional courtyard houses have been drastically transformed and lost their cultural values over time. The quadrangle courtyard reflects the work and art of conventional Chinese residences. An average Beijing quadrangle courtyard building reflects both utility and aesthetics in its design and development. Quadrangle courtyard is designed to have a family-centered pattern with neighbors of the trunk and the community area for social networking and finally denotes cultural profundity. The poor architectural designs and ineffective construction practices have caused many problems in the city regarding sustainability and environmental protection, which has, in turn, increased the concerns of people towards building the traditional houses to ensure better living standards and greater sustainability. This study aims to conduct an evaluation of applications of green construction practices of the traditional courtyard houses on the renovation and reconstruction of contemporary residential buildings in Beijing. </b></p> <p>The study utilizes quantitative approaches for collection and subsequent evaluation of data regarding the subject matter of the research. With respect to the literature review, thesis has performed a review of different literature including journal articles, books, newspapers, and other publications, while for collection of primary data has used with computer-assisted architectural simulation models, which is then analyzed through data triangulation technique. Further, a base model and reference models are generated for computer simulation usingPhoniecs and Green Simulation Studio software's, for the analysis and to analyse the influence of internal courtyard and courtyard for wind flow. The model that exhibits the best width to length ratio and natural room environment is chosen for evaluation.The study was conducted in the residential areas of Dashilar Hutong, Jingyang, Deyang,Dongcheng District, Yue Hutong, Changchun Street Hutong Area, and Yongning District. The study is limited to the given areas only, and no evaluation is performed on other areas of the city and buildings that are not recently renovated or reconstructed. The study also provides recommendations to the architect firms and regulatory authorities regarding applications of green construction practices of the traditional courtyard houses on the renovation and reconstruction of contemporary residential buildings in Beijing. In the assessment, the spatial design of courtyards is balanced; the aspect ratio is planned to crate natural buffer space is created.</p> <p>Further, to examine the performance of the courtyard design the study applied the Computational Fluid Dynamics (C.F.D.) programming, Parabolic Hyperbolic, or Elliptic Numerical Integration Code Series (PHOENICS), for wind condition simulation. Later with the help of the Green build studio of Autodesk, the study had undergone Green Simulation. The Quadrangle courtyard building performance is analyzed by Green BuildingStudio to generate outputs like heating and cooling loads, and monthly electricity and fuel consumption, and their life cycle cost. Results show for a courtyard with a decent combination of courtyard layout and aspect ratiois chosen. Finally, the study suggests the best suited planning strategy for the new proposals and design implications for a new courtyard from the angle of green building construction.</p>

Introduction. Urbanization, intensification of road transport, development of urban infrastructure contributes to increased noise pollution. As traffic flows increase, so do acoustic discomfort zones, and the problem of traffic noise is becoming increasingly environmentally and socially important. Problem statement. The traffic flow significantly exacerbates the environmental problems of cities. One of the most negative factors is the increasing acoustic load. Noise pollution is currently becoming one of the most important environmental stressors. Noise levels depend on the intensity, speed, nature of traffic, type and quality of coverage, land use planning (longitudinal and transverse street profiles, building architecture, traffic lights) and the presence of greenery. Noise leads to an imbalance of auditory adaptation, regulatory processes of the central nervous system, gastrointestinal tract, hemodynamic disorders, the development of noise sickness. At long influence mechanisms of reflex and neurohumoral reactions are broken, there is a nervous pathology, attention decreases by 12-16%. Physiological and biochemical adaptation of a person to noise is impossible, in addition, noise has an inherent consuming effect. Acoustic load has a negative impact on flora and fauna. The main ones are reduced adaptive and reproductive capacity, changes in trophic nets, increased risk of predation, growth retardation, accelerated transpiration, death of leaves and flowers. This problem is most acute for urban ecosystems, as urbanization is one of the main factors in reducing biodiversity due to the loss of natural habitats, their fragmentation or drastic change. In urban conditions, many anthropogenic (industrial, transport noise) is added to the natural noise, which significantly changes the acoustic background. Currently, the noise load in megacities has increased by 12-15 dB, and the volume by three to four times. In cities with heavy traffic, the noise level is approaching 80 dB. Cartographic methods are widely used to visualize and predict noise load. Mapping the noise load of cities is relevant for Ukraine. Currently, acoustic maps have been developed only for certain districts of Kyiv. The creation of acoustic maps will help improve the ecological condition of urban areas. Purpose. Investigate and assess the level of noise load created by traffic flows on the main highways of the city of Khmelnytsky, create an acoustic map and determine the main directions of noise pollution. Research methods. general scientific (generalization, comparison, analysis and synthesis, theoretical and methodological substantiation); mathematical statistics; field (full-scale measurements of noise on the territory); cartographic (construction of a map-scheme) Results. The article highlights the problem of urban ecosystem acoustic load. It is evaluated the noise pollution of Khmelnytskyi city in Ukraine. The noise contamination model is constructed using GIS technologies within modern software package. It is shown that simulation and visualization of noise load using software makes it possible to objectively and detail estimate the acoustic situation and to propose managerial decisions development to protect the population from noise. Conclusion. The intensity of traffic noise depends on the condition and width of roads, the distance of residential buildings from the axis of the roadway. Depending on the capacity of roads, the presence of intersections changes the acoustic load. Reduction of urban traffic noise is associated with absorbing, reflecting, shielding and insulating acoustic ability. Optimization of noise protection of the urban ecosystem depends on a set of architectural and planning solutions. When introducing technical and economic characteristics of noise protection measures, it is necessary to take into account their features (practical limitations and opportunities).

The city of Tirana is subject to constant physical and spatial metamorphosis. In its urban territory, the different residential typologies are well distinguished by socio-economic conditions and the technical-constructive characteristics which have been influenced by political development of the country. The multi-family residential buildings from the post-war period up to the 1990s, in addition to the problems that accompanied them from their initial construction, are found today in front of a physical degradation derived from the years they have. Problematic residential spaces are also most of the buildings constructed in the first decade after 1990, characterized by a low technological and housing quality, derived from an uncontrolled and informal development of the building sector. The building quality in this research, is focused on the applied architectural standards, the technological solutions adopted and the energy consumption derived from them. From the analysis made it has been reached in the conclusions that a renewal and requalification process is necessary to reduce the energy waste and to increase the quality of housing within residential spaces. The main objective of this research is to contribute to the sustainable development of the residential area of Tirana, referring to both the architectural and technological scale. Sustainable development in this paper is closely linked to the quality of residential spaces, which is directly related to the quality of life of the inhabitants. Due to the complexity of the urban environment and its transformations over time, the identification of light regeneration and redevelopment strategies is fundamental, minimizing demolition works. This article includes numerous European examples and a theoretical part, from which proposals for the future development of the residential areas of the city of Tirana can be extrapolated.

The paper is devoted to Stalingrad Tractor Plant, one of the main plants of the Soviet industrialization. The spatial planning pattern of the plant, its settlements, industrial architecture, public and residential buildings are considered herein. Notably, that one of the largest tractor plants in the world was put into operation within the shortest time. Its construction gave a start to the urban development in the north which embodied the advanced ideas in the city planning and architecture of that time. Leading foreign and Russian experts were involved in design and construction works. It is shown that design solutions of residential areas (Upper and Lower) combine both the traditional and innovative principles of the city-planning in the 1920–30s, including the tractor plant and its settlements. It is concluded that whereas residential buildings the early 1930s are characterized by rationality, simplicity, public buildings are expressive and diverse, and represent consistent design principles. The attribution of other objects is also clarified in this paper.

In order to ensure the implementation of the “Strategy for the Development of the Construction Industry of the Russian Federation until 2030” and the implementation of the UN resolution on sustainable development, there is a need to develop new strategic management initiatives. They should allow authorities to make inter-city comparisons, considering specific cities and their objects against the background of others undergoing similar development processes. In this article, the authors propose strategic initiatives for the management of urban facilities. In particular, the authors’ approach to the assessment of the sustainable development of housing and communal service facilities in the city is proposed. According to the authors, the housing and communal city service objects mean capital construction objects in different forms of reproduction. Moreover, the article examines both residential buildings and structures, and utility networks. The authors’ approach consists in the constant assessment of the city’s housing and communal service facilities at different stages of their operation. For this, the authors use several types of analysis: ex post analysis, ex ante analysis, and foresight analysis. For each type of analysis, the authors form a set of assessment indicators and indicate the period of the analysis. The result of the study is the development of an indicator for the assessment of the level of sustainable development of housing and communal service facilities in the city, and a roadmap for their development strategy. The roadmap is formed considering the introduction of modern end-to-end technologies and digital tools into the work of state bodies. The proposed approach, on the one hand, considers the internal complexity and heterogeneity of the city’s housing and communal service facilities. On the other hand, it is a simple tool for the making of effective management decisions by power structures, as it uses data which are available on a regular basis.

Introduction. One of the most objective and reliable indicators of the state of pollution of the aquatic environment and the overall level of technological load on it is the content of pollutants in bottom sediments (BS). There are no large industrial enterprises in and around Yaremche-town (Ivano-Frankivsk region), so there are no significant discharges of toxic substances into the sewage system, especially directly into the river. However, every year in this picturesque cornerof Prykarpattia the number of sanatoriums, recreation centres, cottage towns and just residential buildings grows. Accord-ingly, the Prut River, which is the pearl of this region, quite often gets untreated runoff, which pollutes not only water but also settles on bottom sediments.The purpose of this study was to assess the anthropogenic load on the Prut River based on a comprehensive environmental analysis of the state of pollution of the bottom sediments of this river upstream and downstream from Yaremche.Methods. Water extracts from bottom sediments were prepared by the recommendations of the relevant regula-tions in the ratio "bottom sediments - water" as 1: 5 in terms of the dry mass of bottom sediments. Laboratory study of hydrochemical parameters of selected samples was performed by gravimetric, titrimetric, photometric and other methods of analysis.Research results. The accumulation of ammonium salts, nitrites and nitrates, which are easily soluble, in the far above the discharge site of wastewater, is obviously due to the significant sorption properties of river sludge, which prevents these ions from being washed away by the flow. At the point of discharge of wastewater from the city, the content of these ions increases and reaches a maximum at point 3 - at a distance of approx. 100 m below the discharge site. Further downstream, their number systematically decreases. A similar distribution of concentrations is observed in the case of phosphates. Their source of getting into the river also, for the most part, belongs to the housing and communal services. A significant contribution to the increased phosphate content in the sample below the discharge is made by urban wastewater, in which even after treatment the concentration of phosphate ions remains quite high. The fact of the presence of oil products in the bottom sediments at the investigated area was revealed. The constant increase in the number of road transport on the banks of this resort river inevitably leads to the ingress of products of incomplete combustion of fuel, uncontrolled spills.Conclusions. Upstream from the place of discharge into the Prut River of treated wastewater in the city of Yaremche, the concentrations of salts-pollutants of the biogenic group are formed due to uncontrolled sources of domestic sew-age. In this area, the pollution of bottom sediments is insignificant, slightly higher at the discharge site, and they are of the greatest importance below the discharge. This fact indicates the growing anthropogenic impact of coastal cities on the state of the river and in general, and pollution of bottom sediments, in particular. For the first time oil products were found in bottom sediments in the studied area. The reason for this phenomenon is the constant increase in the number of vehicles on the banks of this river.

Urban development of a modern city should combine and cover most of areas. One of the most important areas that ensure sustainable urban development is the sustainable development of the system of communication. This is one of the most important factors that shapes the city and has a direct influence on urban socio-economic viability, ensuring the quality of the environment and safe traffic conditions. Cities formed in the course of historical processes usually divide into certain areas, centres-cores, peripheral zones, functional centres etc. A territorial communication system, as well as all other infrastructure, must meet the needs of local residents and working people in the broad sense. The article analyses how the communication system infrastructure meets the spatial functioning in order to ensure conditions for work and development. In the case of Vilnius, the level of public transport organisation at the core of the city and peripheral areas is examined. The majority of residents live in residential areas dominated by multi-apartment buildings: Žirmūnai, Lazdynai, Karoliniškės, Šeškinė, Justiniškės and Fabijoniškės are areas populated by more than 5% of residents, with 4.5% residing at Antakalnis and Pašilaičiai. As these areas are easy to reach from work, they constitute the main transport zone of the city with Centras, Žvėrynas, Viršuliškės, Vilkpėdė, Šnipiškės and Baltupiai as intermediary zones. Express buses are serving the main core of the city that covers 27 transport zones out of 50; this territory covers 32% of the total area of Vilnius and the area contains 85% of the urban population and jobs. Šiuolaikinio miesto urbanistinė plėtra turi būti kompleksinė ir apimti daugumą sričių. Viena iš svarbiausių sričių, užtikrinanti darnią miestų urbanistinę plėtrą – susisiekimo sistemos darnioji plėtra. Tai vienas svarbiausių miestą formuojančių veiksnių, turinčių tiesioginės įtakos miestų socialiniam-ekonominiam gyvybingumui, užtikrinančių aplinkos kokybę ir saugias eismo sąlygas. Istorinių procesų eigoje susiformavę miestai, kaip įprasta, dalijasi į tam tikras teritorijas – centrus-branduolius, periferines zonas, funkcinius centrus ir kt. Teritorijų susisiekimo sistemos, kaip ir visa kita infrastruktūra, turi tenkinti tos teritorijos gyventojų ir darbo žmonių poreikius plačiąja prasme. Straipsnyje nagrinėjama susisiekimo sistemos infrastruktūros atitiktis teritorijų funkcionavimui, siekiant užtikrinti sąlygas dirbti ir vystytis. Vilniaus pavyzdžiu nagrinėjamas viešojo transporto organizavimo miesto branduolyje bei periferinėse zonose lygis. Gyvenamuosiuose rajonuose, kur vyrauja daugiaaukščiai, gyvena didžioji dalis miestiečių: daugiau nei po 5 % miesto gyventojų Žirmūnų, Lazdynų Karoliniškių, Šeškinės, Justiniškių, Fabijoniškių rajonuose, per 4,5 % – Antakalnio ir Pašilaičių rajonuose. Visi šie rajonai gyventojų darbo pasiekiamumo pagrindu formuoja pagrindinę miesto susisiekimo zoną, į kurią kaip tarpiniai rajonai dar patenka Centro, Žvėryno, Viršuliškių Vilkpėdės, Šnipiškių, Baltupių rajonai. Greitieji autobusai aptarnauja pagrindinį miesto branduolį, į kurį patenka 27 transportiniai rajonai iš 50, jų teritorija sudaro 32 % visos Vilniaus teritorijos, ši teritorija apima 85 % gyventojų ir darbo vietų.
