Calculation of duplication indicators of the route network at the passenger transportation range

Introduction. Modern transport systems of regional (suburban) passenger transportation face the problem of excessive route duplication between rail and road transport, which leads to irrational use of resources, increased operating costs and decrease in the quality of public services. The relevance of studying route network duplication indicators is due to the need to optimise transport infrastructure, minimise route crossings and increase the efficiency of passenger traffic flow distri bution. At the same time, route duplication is not an exclusively negative phenomenon, as in certain cases it helps to increase transport accessibility and flexibility of passenger movement.

Materials and methods. Methodology has been developed for calculating the indicators of duplication of the route network of railway and automobile transport at the passenger transportation range of the district subordination. Statistical data from Belarusian Railways on the volume and structure of passengers transported by rail by the types of communications, as well as the number of passengers sent from stations along the routes were used; data from passenger transportation operators and car carriers on routes and f lights related to the analysed range. In order to assess the dup lication of passenger transportation routes, the key indicators are the route intersection coefficient, the indicator of the competition of transportation capabilities and the eff iciency of passenger traffic distribution.

Results. Analysis of route network duplication at testing area revealed a high level of railway and road routes crossings in the Minsk — Osipovichi and Osipovichi — Grodzyanka sections. The integral duplication indicator varies from 0.01 to 1.04 and from 0.55 to 5.52, respectively, indicating a different degree of competition and complementarity between transport modes. The authors propose optimisation measures to reduce the frequency of railway routes with the redistribution of passenger traffic f low to road transport, which reduces operating costs and increases efficient allocation of resources.

Discussion and conclusion. The development of an integrated approach to calculating route network duplication at the regional level not only optimises the use of infrastructure, but also contributes to the sustainable development of transport systems, which meets the goals of increasing accessibility and efficiency of passenger transport services.
