In this research, we investigated the possibility of application of the integrated model by applying stated preference data to the integrated model. The integrated model has advantage of way of collecting data and also, fits the theory of micro economics. Therefore, it is desired to be used to economic appraisal of travel time reliability. But the stated preference data, used to collect the integrated model-type data, lacks reliability for the answers. We managed to present respondents the distribution of travel time when route-choice as possible as clear and easy to understand. In the empirical applications, we derived reliable estimated model by investigating the collected data. The computed reliability ratios are around 2.40 implying that the estimated results in the present study are not far from the previous studies. We also found that the effect of respondent's occupancy, area, and so on may be factor of preferences.
