Traffic flow characteristics and their impact on air pollution in urban streets: a case study of Tashkent

Abstract

This study investigates traffic flow characteristics on major streets in Tashkent, focusing on Amir Temur and Fargona Yuli streets, to evaluate their impact on vehicular emissions and air pollution. The analysis examines temporal variations, vehicle composition, and traffic dynamics based on observational data from 2023 to 2024. Key findings highlight peak congestion periods, the dominance of passenger cars in traffic composition, and the significant contribution of heavy vehicles to emissions. The results provide insights into how traffic characteristics influence urban air quality, laying the groundwork for sustainable transportation and environmental policies.
