Subject. This article examines the set of economic relations and problems emerging within the spatial development of settlements and constituent entities of the Russian Federation.
Objectives. The article aims to develop key indicators and methods for assessing transport accessibility, potential market capacity, taking into account socio-economic characteristics, geographical location and the level of connectivity of areas.
Methods. For the study, we used the methods of economic, statistical analysis and synthesis, comparison, and the k-means method.
Results. The article proposes a system of cost-benefit equations for economic agents, and criteria, and a methodology for assessing the Transport Accessibility Index. Based on the clustering of Russian subjects by k-means, the article describes four groups of regions by level of transport accessibility.
Conclusions and Relevance. The practical use of the approach presented to assess the Transport Accessibility Index will help form the basis for management decisions aimed at improving efficiency in the planning of spatial development and assessing the socio-economic effects of the proposed measures. The developed Transport Accessibility Index should be used as part of the analysis and monitoring of the effectiveness of infrastructure expenditures affecting changes in the transport accessibility of settlements within individual regions (municipalities).
