The article is devoted to the study of the pollution level in the city streets by road transport. Purpose. The aim of the work is to operative assess the concentration of pollutants in street canyons in projects for managing the ecological state of the metropolis. Research Methodology. The article used statistical analysis, mathematical modeling. Scientific novelty. A model for assessing the level of air pollution in city street canyons is proposed. On the basis of this model, the concentration of pollutants in the street canyons of the Pechersky district of Kiev was determined, taking into account the daily dynamics of the traffic flows intensity. Conclusions. The research results can be used in the operational forecasting of the pollution level of the roadside space ecosystems, which will allow timely, by controlling the parameters of the traffic flow, to prevent critical situations in which the concentration of pollutants exceeds the maximum permissible values. Key words: management, transport, pollution assessment, traffic flow, design, modeling of pollution fields.

Functional reciprocity of all transport sectors with their infrastructure support is most evident in ports. The port of Split, integrated in Split’s traffic intersection, is a striking example of uniqueness of Split-Dalmatia County as a traffic and economic centre of Central Dalmatia. The development of City’s harbour for passenger traffic and the North Port for cargo traffic has determined already set constellation of relations of maritime, road and rail traffic, and their mutual interference. The road transport and activities with regard to hinterland services generate economic development in which Split is no exception. This estimate is based on changes that can be expected in terms of redistribution of traffic flow in the central and southern Adriatic and the greater role of road transport, with Split having an increasingly important role.

The problem of air pollution of the city is still relevant today. A significant increase of emissions of pollutants from the activities of industrial plants, road transport has a negative impact on the quality of atmospheric air and the environment as a whole, the health of the population. The main objective of this research is to assessment of the state of the air environment, by studying of pinus sylvestris needles, growing on the territory of the city of Omsk. For research of the state of the atmospheric air were chosen 5 key sections in the city of Omsk, where we selected samples of needles. It was found, that the severity of damage and drying of needles is uneven on all key sections, depends on the level of air pollution. An assessment of the state of the air environment was carried out, which showed, that on the territory of the Soviet park and ave. of the Culture (sections 1 and 2, respectively) relatively clean air "norm" was established, according to the third level of pollution. Cathedral square and st. Irtyshskaya embankment (sections 3 and 5, respectively) are characterized by dirty air «harmful», according to the sixth level of pollution.

The main emphasis of this research was to describe air pollution level and dispersion in a typical street canyon (Valdemara Street in Riga (Latvia) city centre), afterward to postulate potential development scenarios and perform modelling in order to understand the influence on air pollution level. For this purpose special mathematical model was used - Operational Street Pollution Model (OSPM), which was developed by the National Environmental Research Institute in Denmark. Following development scenarios were tested: (1) realistic environmentally friendly - decrease of traffic flow by 50 %, as according to street interviews about 36 - 50 % of drivers are ready to change driving habits from car to bicycle; (2) strictly limited – “green light” for public transport, but restrictions for old private cars, flow speed limitations.

Abstract Environmental air pollution is a global health concern, a complex phenomenon which is directly reflected on public health, economic and human development. Environmental air pollution has been drastically multiplied, followed by the beginning of the new Millennia in Prishtina, the capital city of the Kosovo. The new millennium began as a crucial activity for the city of Prishtina in terms of demographic, human geography, social and economic phenomena. The presented study aims to determine prevalent traffic and land morphology composition attributes, which have influenced and continue to have environmental impact in the city of Prishtina. According to the conceptual findings from the empirical observations, the heavy city traffic and the land morphology structure, determine the urban air pollution level. Prishtina is generally polluted due to its geomorphic position in relation to the power plants Kosovo A, and Kosova B. The impact of the above cited factors, is even bigger when the dominant winds prevail through valley, which encompasses the city. The findings from this paper propose the necessity of careful driven urban solutions.

<p>Reducing the risks associated with the effects of polluted air on public health is one of the main tasks of sustainable urban development. This problem can be solved in two different ways: by emission reduction and by minimization of human exposure to elevated concentrations of pollutants. In the context of the second approach, it is important to plan the urban area in order to minimize places with a large number of people and poor dispersion conditions.</p><p>For this purpose investigation and identification of street canyons in Minsk city was performed. With population ca 2 mln inhabitants Minsk is one of the most populated European cities. Due to many historical destructions of the city nowadays it has mainly planned structure of streets and buildings according to General plans of urban development designed in the second part of the XX century. According to the plans Minsk has relatively wide main transport lines surrounded by mid-level buildings and has good conditions for air circulation and air pollutions spatial dispersion. Nevertheless, there is some location in the city with conditions close to urban street canyons and is characterised with high pedestrian and traffic intensity. Besides in modern construction so density planning not so rare. That's in addition to limited air pollution concentration researches makes important measurements and assessments in such conditions in Minsk.</p><p>For sampling, urban canyons NOx concentration in the air were carried out in 2012-2019 in Minsk. Air was sampled on both sides of “street canyons” taking into account weather conditions. During sampling, traffic accounting was carried out. The concentration of NOx was determined by the fluorimetric method.</p><p>Obtained results have shown that the actual formation of “street canyons” occurs even with a low height of buildings along to the streets with heavy traffic. It has been shown that a statistically significant increase of NOx content by 20–50% on the windward side compared to the leeward with buildings height comparable to the width of streets. Besides statistical reliable correlation between emissions levels (assessed based on traffic data) and measured concentrations are observed.</p><p>Identified patterns of air concentration in combination with GIS allow identifying areas with potential increased risk of exposure. This knowledge will help to plan urban territory in a sustainable way.</p>
