Abstract

The article considers the description of the internal sustainability of regional road transport systems through parameters that reflect potential and realised opportunities in regional freight transport operations. There is the author’s vision of the regional road transport system for the transport of goods by road as a target-oriented set of elements, including vehicles, transport infrastructure, technical devices, equipment, and employees, organisational structures that ensure the achievement of management objectives in the transport sector of the region. They conclude that an important element in the management of the functioning and developing road transport in the region is considering the factors that determine the internal sustainability of the system. The paper provides the author’s definition of the internal sustainability potential of the regional road transport system. It proposes an approach to assess the internal sustainability of regional road transport systems based on the elements of regional transport system capacity, such as infrastructure capacity, operational capacity and freight demand capacity in the region. Researchers developed a system of indicators to assess each capacity element from the perspective of the internal sustainability of the system. The article focuses on the study of system stability based on the assessment of deviations from equilibrium states that ensure the stability of the system within its baseline parameters and characteristics, and its adaptability to deviations from the baseline values. It uses regional statistics to assess the internal sustainability of regional road transport systems and describes their internal instability factors. The authors present a visualisation of a model for assessing the internal sustainability of a regional transport system.
