Improvement of the system of transport-transfer hubs on the example of St. Petersburg agglomeration

The article proposes a conceptual framework with empirical foundations, prerequisites, theoretical foundations and implementation, and validity criteria. It also presents methods to improve transport and interchange hubs on the example of the St. Petersburg agglomeration, aimed at improving the efficiency of hubs operation, developing infrastructure and stations, improving the capacity of the transport network, achieving uniform loading system and traffic safety, increasing the attractiveness of rail transport for the population, increasing the index of passenger satisfaction. The analytical review of normative documents, theoretical provisions, programs and measures, carried out and planned for implementation for the development of St.-Petersburg railway junction has been made. The existing models of transport-transfer hubs in the St.-Petersburg agglomeration were investigated and the directions for their improvement were revealed by creating the concept. On the basis of the proposed synergistic-logistic concept, the provisions to ensure the improvement of transport-transfer hubs (on the example of the St. Petersburg agglomeration) have been developed
