ABSTRACT

The article is an original synthesis of accessibility and mobility modelling that is carried-out in the Institute of Geography and Spatial Organization, Polish Academy of Sciences (IGSO PAS). The paper takes into account the spatial context of industry development in Poland, with particular emphasis on the spatial dis- tribution of population, GDP and location of commercial companies. The potential accessibility in HGV trans- port, where attractiveness depends on both population and GDP is taken into consideration. For the empirical analysis the OGAM application was used. In the part of the paper devoted to mobility issues, a model uses the results of the distribution of traffic on the national and voivodeship road network and VISUM software. The original method compares the results of the gravity model for travel between commercial companies carried out by entrepreneurs (businessmen, sales representatives, etc.) with the real traffic distribution. The overestimation/underestimation of traffic with respect to the results of the General Traffic Survey in 2010 was shown. Both in the accessibility and mobility studies a matrix of travel time at the municipal level (2,321 units) was used. Speeds were calculated based on the IGSO PAS speed model. It was pointed out that the potential and gravity models are still not very popular methods of analysis of determinants of industrial de- velopment in Poland. They provide the opportunities for indicating potential locations for new investments in the context of both freight transport and business travel
