The article is focused on evaluating the significance of rail passenger transport in transport contacts between regional centers in Czechia. The review of the particular connections works with the values of the year 2007 and is based on the relationship between supply and demand for rail passenger traffic.
The evaluation is based on the number of rail links within the working day. Real demand data represent the number of tickets sold by the Czech Railways.
Theoretical size of the interaction is obtained by application of the gravity model. In conclusion, the opportunities for the development of infrastructure in the selected connection in relation to transport planning are outlined, using the obtained results.
