JUSTIFICATION OF THE NUMBER OF RESPONDENTS FOR CONDUCTING A SURVEY OF PASSENGER ROUTE CHOICE IN THE CITY ROUTE SYSTEM

Abstract

An approach for determing the sufficient number of respondents whose route choice should be investigated in order to model the passenger route choice in a city route system is developed. The approach allows to assign the acceptable value of the relative error of parameters when defining the utility function.
