The velocity of traffic flow is the primary indicator of road traffic performance and reflects the main goal of movement on the road. This study investigates the velocity characteristics of traffic flow on selected urban road segments in Uzbekistan, including sections of 4R21 (17–18 km), A373a (23–24 km), and 4R2 (20–21 km). By analysing modal speeds, velocity distribution curves, and cumulative density, the research highlights the impact of road conditions and traffic density on overall traffic dynamics. The findings aim to provide actionable insights for improving urban transportation systems.
