The purpose of this publication is generalization of research on the types of urban consolidation, classification of systems for urban freight consolidation by levels, consideration of participants at each level and schemes of their interaction, as well as analysis of direct and reverse flows that accompany this interaction. The works of domestic and foreign scientists on the problems of urban freight transportation and use of consolidation for their solving are the theoretical and methodological basis of the research. Data of official statistical and analytical materials of ministries and departments of Ukraine and world agencies made up the Information basis. When solving the tasks set, methods of economic analysis, systematization, generalization, comparison were applied. The results of the work are classifications of consolidation schemes for urban distribution, urban consolidation centers and their participants. Different levels of urban consolidation allow flexible application of the idea of consolidation to cities of various sizes and topologies, while reducing congestion and improving environmental situation in the city. The forward and reverse flows between various participants in the urban distribution system are evaluated. The prospect of the study is to consider the schemes of consolidation of different levels and an assessment of their economic and socio-ecological efficiency. The limitations of the results obtained are their applicability exclusively for urban areas and for consolidated transportation between cities. The presence of all levels of freight consolidation can be economically feasible only for cities with population of over 1 million inhabitants with corresponding long delivery distances. The practical significance of the study lies in the possibility of using the proposed classification and schemes of direct and reverse flows in the design of urban distribution schemes with the involvement of consolidation centers at various levels.

The development of road transport, both economically and socially, is of great importance for humanity. But along with the tremendous benefits andunlimited potential of road transport, there are many problems, particularly with its operation in human settlements, particularly in cities. Theseproblems are related to the oversaturation of the road network of cities with road transport, which leads to a decrease in speed, congestion, increased traveltime. Ensuring the required capacity of the site is the main indicator of creating conditions for the efficient functioning of the transport system of cities.Each section has its own planning features that allow the car to move at an acceptable speed and at the same time not create any situations that could lead to the formation of congestion.It is known that the lower the speed, the greater the time spent. Speed is one of the most important indicators of traffic flow. Any reduction in the speed of traffic flows compared to the permitted leads to economic losses. And if we consider the reduction of speed, taking into account the stop in motion (delay), it leads to much greater economic losses.

The object of the study is the improvement of traffic management on the main street and road network of the city. Actually, there are many techniques that allow simulating the traffic flows with sufficient accuracy. One of such models is a mathematical model, which allows calculating the main characteristics of a traffic flow on the basis of a few initial data and is considered as a queuing system.Modeling allows pre-determining the impact of traffic management measures on the existing street and road network without creating interference for drivers, making changes to the design of road, increasing the traffic volume, as well as involving the possible overloaded areas.An analysis of the researches of scientists who have considered similar methods in their works had been performed. The fundamental flaw of the mentioned works is that in none of them the study of the model of a real road section was performed for verifying of the model adequacy. Modeling allows understanding more accurately the behavior of an object with less approximations than mathematical models, and provides less researching and forecasting of the system behavior with significant changes in the initial concepts. It is indicated that for the first approximation it is expedient to use mathematical models, and for clarifying the characteristics – to use non- mathematical methods, in particular, simulation.It is proved that simulation is a powerful tool for studying the behavior of real systems. It is mainly used to study situations and systems that can be described as queuing systems.Using the queuing theory, it becomes possible to perform certain calculations and determine indicators of effectiveness of the queuing system.Obtained result of the indicators will help to determine the street and road network areas where a traffic jam may form for any reason, where the road will be overloaded. This makes it possible to develop a high-quality algorithm for quick elimination of traffic jam.
