The article is devoted to the study of changes in the intensity of traffic flows in the street canyons of Kyiv and to determine the dynamics of the intensity of emissions of major pollutants during the day. Due to the rapid growth of the vehicle fleet, there is a significant congestion of the street and road network of cities, which leads to a set of environmental problems. One of the such problems is air pollution with harmful substances. Object of the study: dynamics of pollution of city streets Purpose of the study: study of changes in traffic intensity during the day and assessment of the dynamics of the level pollution of the cities road network. Method of the study: statistical methods, cluster analysis. The change in the level of pollution of city streets during the day depends on dynamic factors, namely the intensity and quality of the traffic flow, meteorological conditions and so on. It is established that the most dangerous intervals of the day will be "peak" periods during which the maximum values of traffic intensity are observed. The article examines the patterns of distribution of traffic intensity during the day and on the basis of determining the environmental performance of real vehicles, technical and operational characteristics of which correspond to the characteristics of "efficient" cars of the corresponding category, determines the daily distribution of emissions of major pollutants. Thus, the obtained results can be used in determining the concentrations of pollutants in the street canyons of cities, which will make operational predictions of the level of air pollution. KEY WORDS: STREET ROAD NETWORK, TRANSPORT FLOWS, TRAFFIC INTENSITY, STREET CANYON, VEHICLE, POLLUTION LEVEL.

Abstract One of the key elements of environmental protection is taking care of air quality. This is a difficult task as the quality of air is influenced by numerous factors connected with man’s activity. Usually more developed economies have a stronger influence on the environment, including the level of pollution, and at the same time they have at their disposal a number of tools that make it possible to stop the emission of harmful substances. An important aspect in the struggle with air pollution in a given area is the constant monitoring of its quality. The aim of the article is the statistical and econometric analysis of the basic parameters of air pollution in Czestochowa in 2012–2017. This objective was achieved by calculating the basic descriptive statistics of the distinguished types of pollutants, determining the correlation between them, and building models of fluctuations in time for each of them based on the data observed and corrected (standardized) relative to air temperature. Based on the obtained models – assessing their prognostic properties – the prediction of the level of the selected types of pollutants was made.

Air Pollution Monitoring

In today’s world, due to the fast growth in number of motor vehicles and industrial evolution, the environment around us is more polluted. The pollution majorly affects the quality of air and causes the major health issues to living beings. The major reason for atmosphere contamination is due to releasing of harmful gases like carbon di-oxide, carbon monoxide etc. from factories, vehicles and from combustion of fossil fuels. It is necessary to monitor the percentage of pollutant present in the air which will leads to environmental issues. To overcome this, we have designed a tool using IoT technology. The air pollution monitoring tool includes Microcontroller and Sensors that provides the provision to monitor the quality of air by detecting the harmful gases present in the atmosphere. The pollution level can be monitored remotely using PC or smart phones. The data is store in cloud and can be accessed remotely.

Purpose. Estimation of atmospheric air pollution level in the Dnipro city in modern conditions and technogenic loading on the air basin of the Dnipropetrovsk region. Methods. Statistical. Results. Volumes of pollutant emissions from stationary sources are 4 times more than emissions from mobile sources. The maximum values of emissions of pollutants are noted for the enterprises of the processing and extractive industry. The estimation of the level of air pollution in Dnipro city was carried out. An increase in the level of contamination in Dnipro city was indicated during the study period. Substances for which the quality of atmospheric air constantly does not meet the standards include dust, nitrogen dioxide and formaldehyde. The level of atmospheric air pollution can be classified as «polluted» and «highly polluted». The module of technogenic loading on the air basin of the Dnipropetrovsk region and Dnipro city was calculated. The rate of the technogenic loading in Dnipropetrovsk region from stationary sources considerably exceeds the mobile ones. In Dnipro city, the level of technogenic loading from stationary sources is an order of magnitude higher than the corresponding in the region. This indicates a significant level of technogenic loading on the Dnipro city air basin exactly from stationary sources. The volume of pollutant emissions from stationary sources in the region is an order of magnitude higher compared to the same in Dnipro city and the area of the region is two orders of magnitude larger. The reduction of the level of technogenic loading on the air basin of Dnipropetrovsk region as a whole was noted. Conclusion. Dnipropetrovsk region belongs to regions with significant industrial potential. The primary tasks for the improvement of the air basin are the development of measures to reduce emissions from stationary sources, as well as optimization of the monitoring system in order to determine the list of priority pollutants.

The protection of the environment and people’s health from negative influences of the pollution of air as a medium of the environment requires constant observing of the air quality in accordance with international standards, the analysis of emission and imission of polluting matters in the air, and their connection with the sources of pollution. Having in mind the series of laws and delegated legislations which define the field of air pollution, it is necessary to closely observe these long-term processes, discovering cause-and-effect relationships between the activities of anthropogenic sources of emission of polluting matters and the level of air degradation. The relevant evaluation of the air quality of a certain area can be conducted if the level of concentration of polluting matters characteristic for the pollution sources of this area is observed in a longer period of time. The data obtained by the observation of the air pollution are the basis for creation of the recovery program of a certain area. Vranje is a town in South Serbia where there is a bigger number of anthropogenic pollution sources that can significantly diminish the air quality. The cause-and-effect relationship of the anthropogenic sources of pollution is conducted related to the analysis of systematized data which are in the relevant data base of the authorized institution The Institute of Public Health Vranje, for the time period between the year of 2012. and 2017. By the analysis of data of imission concentrations of typical polluting matters, the dominant polluting matters were determined on the territory of the town of Vranje, the ones that are the causers of the biggest air pollution and the risk for people’s health. Analysis of the concentration of soot, sulfur dioxide and nitrogen oxides indicates their presence in the air of Vranje town area in concentrations that do not exceed the permitted limit values annually. The greatest pollution is caused by the soot content in the air, especially in the winter period when the highest number of days with the values above the limit was registered. By perceiving the influence of natural and anthropogenic factors, it is clear that the concentration of polluting matters can be decreased only by establishing control over anthropogenic sources of pollution, and thus it can be contributed to the improvement of the air quality of this urban environment.

Fine particulate matter with a diameter less than 2.5 �m (i.e. PM2.5) is an air pollutant of special concern for urban areas due to its potential significant negative effects on human health, especially on children and elderly people. In order to reduce these effects, new tools based on PM2.5 monitoring infrastructures tailored to specific urban regions are needed by the local and regional environmental management systems for the provision of an expert support to decision makers in air quality planning for cities and also, to inform in real time the vulnerable population when PM2.5 related air pollution episodes occur. The paper focuses on urban air pollution early warning based on PM2.5 prediction. It describes the methodology used, the prediction approach, and the experimental system developed under the ROKIDAIR project for the analysis of PM2.5 air pollution level, health impact assessment and early warning of sensitive people in the Ploiesti city. The PM2.5 concentration evolution prediction is correlated with PM2.5 air pollution and health effects analysis, and the final result is processed by the ROKIDAIR Early Warning System (EWS) and sent as a message to the affected population via email or SMS. ROKIDAIR EWS is included in the ROKIDAIR decision support system.

The development of road network infrastructure is an important component of the economic development of the European Union. Updating of the road network contributes to the integration of the economies of countries into a coherent whole. The road network provides the free movement of citizens, the movement of goods and the effective implementation of various services. The increase in the length of the road network leads to an increase in the financial and material costs necessary to ensure its maintenance and repair. One of the ways to reduce costs is by strengthening the physic-mechanical and operational characteristics of the pavement due to the widespread use of cement concrete. The quality of the pavement of cement concrete depends largely on the rational selection of its composition. This allows a significant increase in the durability of road pavement. The purpose of the research was: the development of recommendations for the rational selection of the composition of the road pavement material of cement concrete, aimed at upgrading longevity, and taking into account its frost resistance grade. According to the goal, the following tasks were developed: the analyses of the climatic zones in which the road network of the European Union is located; the development of a research plan, a selection of the response function and influence factors; the study of physico-mechanical and operational characteristics of the researched material of road pavement; on the basis of the obtained data, the calculation of the complex of experimental-statistical models, which describe the physico-mechanical and operational characteristics of the road pavement material; on the basis of experimental statistical models, a method was proposed for selecting the rational compositions of the cement concrete pavement road material depending on the conditions of its application. The results presented in the article can be used in engineering and scientific practice for the selection of road pavement from cement concrete for highways.
