The expert system, created in this paper, has been envisaged as a tool to be used on operational and strategic level in some segments of transport planning. The basic idea for creating such an expert system was to define relations in modal split on the basis of parameters of transport system demand and supply in one city. To enable the use of this expert system on a strategic (planning) level and on an operational level, it is necessary to determine the parameters which could be forecasted on a short-term basis and on a long-term basis. For planning purposes, such an expert system should determine margins of share of the specific transport modes. These limits should serve as benchmarks in forecast of the relations in modal split during the planning period, on the basis of which, specific elements of future transport system are to be defined. In a similar manner this expert system can be used for operational purposes, providing that a survey of parameter values is performed in the existing state or that a short-term forecast for these parameters is made.
