The estimation of the passengers' preference is the key task for transportation planners for solving the wide range of optimization problems in the field of public transport. A methodology for estimation of the passengers' preference when choosing the bus line within a public transport system is developed in this paper. The proposed approach is based on the fuzzy-logic mathematical apparatus and uses the surveys' data to calculate the membership functions defining the passengers' preference. The case study of the passengers' survey, held in Talas (Kazakhstan), is used to illustrate the developed methodology.
