Validity of Revealed Travel Time Data from Geography Information System in the Estimation of Zonal Travel Cost Model

Zonal travel cost model was applied to estimate non-market value of Hahoe folk-village. Geographical information system(GIS) was used to derive the most optimal zonal TC model. Author proposes GIS-derived ‘travel time’ be used as a proxy variable in numeration of travel cost instead of ‘travel distance’ dominantly being used in the standard model. Linear, semi-log and double-log models were applied to find an optimal equation model, and FGLS and EGLS were used to remove the problems of heteroscedasticity and serial-correlation. Finally, the Marshallian consumer’ s surpluses from standard ZTCM, travel time and travel distance applied models from GIS were calculated and compared.
