Received 22 October 2020; Revised 26 December 2020; Accepted 09 January 2021; Published 01 February 2021 Abstract Air pollution is a cause for serious concerns in urban areas in Republic of North Macedonia. Intensive development of road transport increases the main air pollutants’ concentrations - particulate matter and nitrogen dioxide, whose monitored values are continuously exceeding the limit. The main disadvantage of the national plans and annual reports is the absence of comprehensive and categorized list of reduction/mitigation measures for road transport impacts on air quality. Analyzing the current air pollution problem and road transport contribution this paper provides the needed and detailed categorization of short-to-long term reduction/mitigation measures consisting of five subcategories. Based on measure categorization, a guiding frame for urban air quality is designed, intended for further support and assistance for local authorities in the process of air pollution control. Designed with integrated activities, the air quality guidance enables them to select suitable measures to manage road transport pollution and to evaluate their effects estimating the changes in air pollution levels. Hence, the guidance can be used for thorough planning of air quality issues caused by road transport and for policy making. Contributing for urban air quality improvement the guidance is a first step towards the implementation of air pollution management in urban areas.

Biggest air pollution impact on health and economy results from exposure to increased levels of toxic pollutants leading to rising occurrence of diseases and premature death [1]. Air quality is a major concern particularly in urban areas where traffic is very intensive. There, road traffic is recognized as the biggest single contributor to two of the most harmful and widespread air pollutants – nitrogen oxides (NOX) and particulate matter (PM) [2]. Republic of North Macedonia is not an exemption. Air quality remains poor in most of the towns in the country. Ambient concentrations of one of the most damaging air pollutants, fine particulate matter, are often several times above permitted levels. The situation is most serious in the biggest urban centers in R.N. Macedonia: Skopje, Tetovo, Bitola [3]. Several sources and reasons for these problems with air quality have been identified, but they may differ not only in one urban area, but also between several urban areas. Apart of the industry, energy production, households heating with wood and agricultural activities, road transport is also a significant source of air pollution in urban areas [4]. * Corresponding author: beti.angelevska@tfb.uklo.edu.mk http://dx.doi.org/10.28991/cej-2021-03091651 © 2021 by the authors.
