Statistical Analysis of the Development of Ukraine's Transit Infrastructure in the Conditions of European Integration and War

The article is devoted to a comprehensive analysis of the Ukrainian transport and logistics system in the conditions of a full-scale war and deepening integration with the European Union. The article examines large-scale structural changes in transit flows, the dynamics of freight transportation by various modes of transport, as well as current trends in the development of border infrastructure. Particular attention is paid to the revision of European transport policy, the expansion of the TEN-T network with the participation of Ukraine, the attraction of EIB investment resources and the effectiveness of the Solidarity Corridors programs. Based on official statistical data, international reports and government documents, the scale of economic losses in the transport sector was examined, in particular the destruction of infrastructure facilities, the reduction in freight transportation volumes and the change in the structure of logistics flows in 2021–2024. A comparative analysis of the volumes of rail, road, sea, river and air transportation before and after 2022 was conducted, which made it possible to identify the key factors in the decline and subsequent recovery of the sector. The article shows that rail and sea transport suffered the greatest losses, however, due to the reorientation to the western direction, the intensification of cross-border transportation and the creation of new logistics routes, a gradual recovery of cargo flows is observed in 2023–2024. The positive dynamics of intermodal and container transportation are separately studied, which indicates the strengthening of Ukraine's role in European supply chains. It is concluded that the development of transit infrastructure, the modernization of border crossings, the inclusion of Ukraine in the updated TEN-T network and the expansion of cooperation with Poland, Romania, Slovakia and Hungary form a strategic basis for the long-term integration of Ukraine's transport system with the European market and ensure its increase in its role as a key transit center of Eastern Europe
