The purpose of study is to verify the value of data for the travel time. For this survey, models for travel cost using the travel time of direct stated data and the estimated travel time of indirect revealed data through GIS(Geographic Information System) program were derived respectively. The goodness of fit for the models had been compared and superior model was selected. For the more, these models enable us to compare the estimated value. Consequently, the model using estimated travel time of indirect revealed data was relatively superior and the model using the travel time of direct stated data overestimated ten million won per visit. Thus, it is essential to adapt estimated travel time of indirect revealed data through GIS program for estimating a travel cost model.
