Simulation of vehicle movement at unregulated intersections of public roads.

Developments in the field of computer software for modeling transport processes and their analysis represent modern software products that are becoming a powerful modeling tool. In the world practice, well-known simulation software products in the field of traffic flow organization are widely used, one of which is VISSIM (PTV AG, Germany). The PTV VISSIM simulation software can greatly simplify the work of the designer and creates a reliable platform for the design of road transport and urban planning facilities. To date, the first steps have already been taken in Ukrainian practice to address the issue of the feasibility and relevance of using transport modeling in Ukraine, especially in assessing the effectiveness of design solutions for road infrastructure. The purpose of the article was to present the results of traffic flow simulation to assess the availability and number of free traffic intervals between vehicles while driving at intersections of public roads using PTV VISSIM. The object of experimental research was an unregulated intersection of highways at the same level H-01 Kyiv-Znamianka (category II) and O100209 Uzyn – Vasyliv – Hermanivka – Trypillia (category IV). To achieve this goal, the following tasks were solved: a simulation model was developed at the experimental site (unregulated intersection); the availability and number of free traffic intervals for the existing traffic management option was assessed; measures to increase the number of free traffic intervals at the selected experimental research site were proposed and their effectiveness was evaluated.
