Abstract
The purpose of this study is to conduct a thorough analysis of the current state and possible prospects of the technogenic impact of motor transport on the environment in cities.For this purpose, some densely populated cities located in the south of Kazakhstan in sandy areas were investigated, in particular, one of the busiest by motor transport -the city of Shymkent.The scope of the study was determined in accordance with its key elements, namely, regional types of aggregates of technogenic impact and a comparative analysis of the impact of motor transport on the environment in cities.The data of the national air quality monitoring network were obtained through the existing national network of Kazhydromet stations.As a result, only historically-stable indicators were selected, supplemented by the results of field studies by the Research Institute of Transport and Communications (RITC), the Centre for Strategic and International Studies (CSIS), and regional opportunity indices (RCI) determined by the global consulting firm Whiteshield Partners.The study found that some vehicles, such as those with outdated emission standards, high mileage, or failures in engine emission control systems, contribute disproportionately to the total emissions, and reducing the number of heavy vehicles and improving the quality of the road surface can help reduce emissions.
