The accessibility of Poland’s Space to the Trans-European Transport Network

The aim of the article is to analyse the land transport accessibility of two trans-European corridors within the boundaries of Poland. The adjustment of the course of transport routes to the distribution of the population and the country’s land development (including economic potential and logistic infrastructure) was outlined using measurements of cumulative accessibility. The results were presented in both cartographic form (isochrone approach) and tabular form (cumulative approach). Research was conducted adopting different forms of transport used for relocation (including foot traffic, car, rail and multimodal transport) and both the current and target layout of the transport network. This made it possible to determine the changes that will effectively run the process of investment in transport infrastructure on Polish territory. This allowed the identification of the areas of Poland which are particularly conveniently located in relation to domestic connections (in terms of the international network) and those for which the European transport network remains difficult to access
