Relevance. Passenger road transport in the 90s of the last century showed a high rate of transition to new management methods. The subsequent streamlining of activities progressed unevenly, mainly through regulation. However, important problems in the development of the industry, especially in the regions, have not been resolved. A crisis situation in intra-regional inter-municipal transportation and a high accident rate are the example. To a large extent, this situation is caused by the lag of the modern interpretation of the regional passenger road transport system from its real state, which does not allow achieving the greatest effect in the development of passenger road transport. The purpose of the work is to increase the importance of regular passenger transportation based on the substantiation of the importance of the structural parts of regional passenger motor transport systems, the developed methodology for assessing their condition, and creating development rules taking this into account.Materials and methods. General scientific methods of analysis and synthesis, system analysis, mathematical statistics, as well as the provisions of the theory of transport processes and systems are used in the work. Modern general scientific software products, open information resources about passenger vehicles in the regions were used.Results. The main scientific result of the article is the introduced concept of a regional passenger motor transport system. For a quantitative assessment of its condition, an indicator of the level of system self-organization has been developed, which is determined by the ratio of the number of cars to the number of buses, trolleybuses and trams in the region. The values of the indicators are in the range from 74 to 543 with an average value of 277. The dependencies of the influence of gross regional products and the number of population in the regions on the number of buses and cars in them are revealed. The practical significance lies in the development of tools for assessing the state of regional passenger transport systems. The directions for further research to determine the influence of structural parts on the level of self-organization of the system, building on this basis effective regional strategies for the development of passenger road transport are related.
