Transport models are mathematical tools necessary for many transport analyses. They are applicable among others in economic analyses, and especially in the development of feasibility studies. One of the key elements of such models is their credibility, which results from good technical assumptions. Important information is undoubtedly information about the spatial development of the area under investigation. Much data on the attractiveness of particular areas, so-called transport zones, needs to be collected when constructing a transport model for urban areas. The paper presents the ways of obtaining and aggregating data to determine measures of transport zones attractiveness for daily trips in the example of Bydgoszcz and Torun.
