The research part of the survey includes defining and determination the transport capacity in transportation graph where the potential of railway and bus transport in Bulgaria is rated.

A mathematical model has been derived to assess the potential of the rail passenger transport to increase his capacity and efficiency. This potential has been evaluates in comparison with the competition of the bus transportation. A specific transportation route has been chosen from Sofia to Varna and the potential for increase of the rail transport has been evaluated. The mathematical model uses optimization problem, related to the evaluation of a maximal flow in a transportation network.
