The Use of Potential Models in Research on Transport Accessibility of Knowledge and Innovation Centers on the Example of Poland

In a knowledge-based economy, innovativeness is considered to be the main factor of regional development. Economic development on a regional and national scale is initiated in the urban agglomerations, in which there is a highest concentration level of knowledge, information, and tangible and intangible capital. The potential for innovation implementation is placed unevenly, which makes the spread of innovations and knowledge dependent on the transport accessibility of these places. The concept of transport accessibility and the possibilities for the use of potential models for the research on transport accessibility is presented in the article. It also covers the results of the research on the differences in transport accessibility of knowledge and innovation centers in different Polish regions which was based on the indicator of potential transport accessibility.
