TRANSPORT MODEL AND ITS DEVELOPMENT IN THE MACROMODELING ENVIRONMENT

In the modern context of infrastructure development, the need for change in the organization of transport activities, and significant transport saturation, there arises a necessity to create effective transport models for planning and managing such systems. A transport model is a tool that allows the exploration, analysis, and prediction of interactions between different components of a transport system, considering the behavior of traffic participants, transportation volumes, and the impact of unforeseen external factors. One of the most common approaches to creating such models is the use of modeling methods, which allow for the evaluation of general patterns in the functioning of a transport system at the city or regional level, identifying key problem areas, and developing strategies for their resolution. Thanks to the possibility of virtual experimentation, transport modeling helps to avoid financial costs and risks associated with real-world changes, and answers the question «what will happen if?». This article discusses the process of creating a transport model, highlighting the main stages of its construction, including data collection and processing, model calibration, and modeling of various development scenarios. The advantages of using models are revealed, particularly in forecasting the consequences of management decisions, implementing infrastructure projects without risks and costs, optimizing transport flows to achieve the best results, and many other areas. Special attention is given to the practical aspects of applying software tools for modeling, which allow for the creation of detailed transport system models, analysis of various infrastructure development scenarios, and the prediction of their changes. The use of such tools ensures calculation accuracy, simplifies the planning process, and helps to make well-grounded management decisions.This article is relevant and useful both for the scientific community and practitioners in the field of transport planning.
