ECOLOGICAL ASSESSMENT OF THE DEGREE OF INCREASING ENVIRONMENTAL POLLUTION IN THE ZONES OF LIGHT REGULATION

Abstract

The article is devoted to the study of the increase in emissions of carbon monoxide and carbon dioxide (CO and CO₂) during a car idle in front of a traffic light. The results of a road test with measurements using a smartphone and a diagnostic scanner of vehicle speed and fuel consumption, and the results of calculating air consumption, the amount of combustion products and the intensity of CO and CO₂ emissions. An ecological assessment of the degree of increase in the emission of the above substances is proposed by comparing the intensity of emissions during idle time in front of a traffic light and the average intensity of emissions while driving in the urban cycle, as well as by comparing the results obtained with the Euro-5 standards. The study shows that emissions of harmful substances in traffic light control zones are increasing and do not fit into the current standards, which proves the negative impact on the environment of significant idle time of cars in front of traffic lights.
