The article provides a comprehensive analysis of the factors determining the critical environmental state of the air basins in modern Ukrainian cities. It is established that the abnormally high toxicity of transport emissions in Ukraine, compared to European Union countries, is caused by the cumulative effect of the rolling stock’s technical degradation (predominantly Euro-2 and Euro-3 classes), the widespread practice of unauthorized removal of exhaust aftertreatment systems (catalytic converters and particulate filters), as well as low fuel quality with excessive sulfur and aromatic hydrocarbon content.
In view of the strategic goals of sustainable development, the study substantiates that a radical improvement of the environmental situation in urbanized areas is possible only through a fundamental restructuring of the urban passenger transport fleet. The object of the study is the transport network of Cherkasy, for which a mathematical model for predicting harmful substance emissions was developed. The model is based on calculating the total annual emissions of major toxicants (NOx, CO, PM), taking into account the specifics of main transit routes, average daily mileage, and differentiated emission factors for various engine environmental classes.
The scientific novelty of the research lies in the verification of a scenario for replacing medium-capacity buses with large-capacity units (Euro-6 standard) at a 2:1 ratio. The simulation results for Cherkasy confirmed the possibility of reducing nitrogen oxide emissions by 90% and cutting energy consumption by 30%. The proposed approach allows administrative authorities to adequately assess the environmental efficiency of investment projects in the transport sector and to formulate justified requirements for carriers within tender procedures. The practical significance of the model lies in its potential extrapolation to other industrial and logistical centers in Ukraine to predict the outcomes of urban infrastructure modernization.
