The Link between the Development of Road Transport Infrastructure in Poland and the Changes in Transport Accessibility at Regional Scale

Transport infrastructure affects the level of transport accessibility. The impact can be direct or indirect. The development of transport infrastructure directly affects the spatial and temporal accessibility of transport, shortening the distance and travel time. The indirect impact of transport infrastructure on transport accessibility manifests itself in improving the competitive position of the region and individual companies. The article aims at presenting the impact of the development of road transport infrastructure on changes in the level of regional transport accessibility in Poland. Separate attention is paid to the changes in the spatial layout of transport availability. The evaluation considered the most recent data from the Central Statistical Office, and the scope of the analysis looks at 2008 to 2018. In the context of improving transport accessibility, an assessment of the investment consisting in the construction of the S3 expressway was also presented.
