The object of research of this work is the traffic flow and its parameters in a critical, in terms of traffic congestion, area of the city, namely at the entrance to the bridge that connects the right and left banks of the Dnipro River (Dnipro, Ukraine). A problem arising in the formation of traffic flows to the bridge is the occurrence of congestion due to the physical limitation of the carrying capacity of the bridge. The peculiarity of the traffic interchange near the bridge is that it is impossible to expand the roadway to increase the traffic capacity without a major overhaul. In addition, the surrounding infrastructure maintains an intense pedestrian flow, which is wedged into the traffic flow in arbitrary locations, which leads to a breakdown of the flow structure or its stopping. There are also several additional factors that complicate the flow structure and delay it. The solution that can improve the situation at the lowest cost is the introduction of automatic regulation of traffic and pedestrian traffic in critical places.
To determine the regulation points and their modes of operation, an analysis of the transport environment in the area of entry to the bridge was carried out using field research. The modeling of traffic flows was carried out using the software package and the mode of operation of the traffic light was chosen.
Statistics were obtained regarding traffic flows along adjacent streets and the traffic flow was schematized. The location of the traffic light and the time intervals of its work, which allow to minimize congestion on adjacent streets and increase the speed of travel, have been determined.
A special feature of the study was the use of the powerful AnyLogic package for modeling, which contains a specialized module for working with traffic flows. Its application made it possible to create a movement model and conduct a series of experiments, according to the results of which time intervals of regulation were obtained.
