N2  - This paper contributes to discussion on introduction of exclusive lane for public transport. Analyses of results have been presented on effectiveness of usage of a 4 - lane and a 6 - lane street with and without an exclusive lane for buses. Two basic sub-models have been applied: - the binary logit model for modal split estimation; it takes into consideration the relation of travel time performed by private cars to public transport, - the polynomial model for predicting link impedance; the real travel time is affected by relation of traffic volume to the design capacity The parameters of both sub-models have been calibrated for the Polish conditions. The relationships are determined between number of person trips and traffic volume of buses/private cars, market share of public transport in motorised trips, average travel time lost in trips, average operation cost. An iterative technique addresses a feedback between the modal split and traffic volumes. Numerical calculations by use of EXCEL and MATLAB were carried out. Typical values of corridor length, occupancy rate of passenger car, design capacity of the bus, access and egress time to and from the parking/bus-stop in urban areas were applied. On the basis of the estimated results, the marginal parameter values: number of people carried at which separated lane for buses is most effective , traffic volume for private cars, traffic volume for buses and share of public transport in trips have been got by consideration of the average travel time lost and operational cost as criteria: Then introduction of street lanes with and without exclusive lane for buses in relation to number of person trips can be optimized.
