Research into the patterns of traffic flow distribution at the entrances to large settlements in conditions of urbanization

Abstract

The increase in traffic intensity and the change in the composition of the traffic flow gradually lead to the overloading of highways and streets of major importance with traffic flow, especially in conditions of urbanization. The action of dynamic loading in such cases is replaced by static loading, which can lead to premature destruction of the structural layers of the road surface. This, in turn, requires new research and the adoption of other design decisions. Based on an analysis of literary sources, publications, reports on traffic intensity and composition of traffic flow in previous years, and technical documentation on the availability of public roads within Ukraine, the article substantiates the feasibility of recording traffic intensity and composition of traffic flow. As is well known, available data on traffic intensity and composition of traffic flow is an important transport and operational indicator that makes it possible to justify and plan the scope and timing of repair work, improve road conditions and traffic safety, and subsequently ensure the traffic capacity of the motorway in accordance with the design category based on the level of traffic congestion both within a single region and along transport corridors and logistics routes passing through the territory of Ukraine.

For different categories of motorways and the financial capabilities of service organizations or balance holders, automatic counters, video recording and video recording, as well as the method of visual control and accounting of vehicles, currently exist and are widely used to determine traffic intensity and the composition of traffic flow. To achieve the set goal, traffic was recorded visually for both directions at temporary recording points from a vehicle. Preference is given to visual traffic intensity accounting, since automated devices have limited capabilities for classifying vehicles by type. The results of a study on the accounting of vehicles on state highways within the Kharkiv region and on the approaches to the regional center, the city of Kharkiv, are presented, and a methodology for calculating the actual values of the number of vehicles to the indicators of average annual daily traffic intensity is given.
