Problem. The purpose of vehicle speed studies is to identify general trends in speed and its rational limits, to assess the level of traffic safety, to forecast harmful emissions into the air and to provide an integrated assessment of travel time in urban networks that takes into account the random nature of this variable. Its assessment is particularly relevant in urban environments where traffic conditions cannot be considered free. Transport situations here often limit space and maneuver time, as well as reducing opportunities for drivers. Different drivers' reactions to the difficulties in traffic can lead to an increase in the level of speed randomness, which requires very careful attention to the parameters of its distribution. Previous studies in this direction have confirmed such trends but have not let definitive conclusions about the nature of speed distribution in urban streets. Goal. Testing the hypothesis that the gamma distribution is suitable to describe the speed oscillations of the same type of vehicles in different conditions. Methodology. Statistical evaluation of vehicle speed actual values in the stop-line front of the urban signalized intersection by means of the distribution theoretical law and regression analysis of the relationship between the mathematical expectation and the form parameter of the gamma distribution of speed. Results. The hypothesis that the gamma distribution can be used to describe oscillations in the speed of similar vehicles under different conditions has been confirmed. Originality. The speed of cars and motorcycles under new driving conditions was assessed. Practical value. The obtained result allows increasing accuracy of the car and motorcycles speed prediction in analytical and simulation models of transport networks functioning.
