In the work, the average operating speed of the tram is investigated on the sections with the high density of the road network. Such peculiarities are inherent to the cities where its configuration has developed historically, and trams move in the general structure of traffic flow which is predetermined by the absence of traffic capacity reserves in the old, as a rule, central part of the city. It frequently causes the reduction of the whole traffic flow speed of movement, in particular on the intersections and within public transport stops. Determination of the mutual impact of automobile movement and trams is topical because, on the one hand, trams, taking into account their dynamic and technological movement peculiarities, worsen traffic flow indicators, and on the other hand, vast traffic intensity causes downtime of the trams rolling stock in the queues before the intersection that decrease passenger transportation quality. As a result of the research reported in this paper it was managed to determine the amount of change of the average tram operating speed for different methods of traffic flow control for different times of day
