Internode regional rail connections on the example of the Opole province

Summary/Abstract: The growing role of rail transport is a contribution to research on regional rail transport within individual voivodships. In the context of personal transfers, the actual transport accessibility based on the real connections system becomes extremely important. The research area is the Opolskie Voivodeship. The author on the basis of inter-connection links: the number of direct connections, the number of connections with transfers, the number of transfers and travel time, has analyzed the regional connections network. Nodes are stations with at least three active personal directions and local activity centers – municipal capitals. The total number of nodes was 51. The analysis showed a significant polarization of the transport offer (on average, 10 pairs of connections depart from each node) and the threat of defragmenting the network to local systems (Kluczbork and Opole). The Brzeg–Opole–Strzelce Opolskie route has been recognized as the main route of communication, which should be the skeleton of the regional transport system. The positive aspects of the functioning of the transport system, author included: low number of transfers necessary for inter-node travel. Most displacements between nodes are possible with one change. In the aspect of network connections (direct connections), the average rank of the node was 7 (that is, with every node in the network, on average, each node had a direct connection). The network has a large number of nodes with low connections. In addition, the author calculated the betweenesses and closeness indicators, which emphasized the role of the most important nodes: Opole, Kluczbork, and Nysa. Local networks play an important role in network systems, which allow linking two networks (eg. Opole–Kluczbork). The possibility of transport development includes the support of links to the main transport corridor and the system of railway feeder lines.
