Title: EXPERIMENTAL STUDY OF TRANSPORT FLOWS IN BIG CITIES Keywords: traffic, transport, flows, speed, emissions Abstract: In the present work a methodology has been developed to study some parameters of traffic in characteristic sections of urban infrastructure. For this purpose, the average driving speeds, average fuel consumption and their impact on environmental performance are determined. The traffic in the road infrastructure of the capital of Bulgaria -Sofia has been studied. In the study, the road infrastructure is divided according to the degree of traffic load into three main groups. These are transport sections in the center of the city with high traffic during heavy traffic hours, sections with medium load and sections of highway type. An experimental study was performed for the three types of sections. For these sections the speeds of movement in typical time zones, fuel consumption, the speed of the car’s exhaust gases and ecological indicators were measured. References Issue
