Optimization of empirical models of transport planning in railway transport

This paper is focused on analysis of the empirical models of transport planning in railway transport. At first are described general information and basic principles about known models. In the second chapter are mentioned current empirical models used in railways transport. There are explained methods of calculations for Nyvig and Lill's gravitational model at all and introduced comparison of optimal values with actual values at chosen transport routes according to Lill's model. The third chapter includes proposal of the extension the current Lill's model including the practical application at the concrete chosen transport route.
