 note = {The aims of this paper i) to present a methodology for incorporating revealed preference (RP) and stated preference (SP) data in discrete choice models，ii) to apply the methodology to intercity travel mode choice analysis，and iii) to predict new mode shares for each O-D pair resulting from changes in service levels. The combined estimation technique with RP and SP data is developed to promote advantages of the two complementary data sources. The empirical study of intercity travel demand demonstrates the practicality of the methodology by accurately reproducing observed aggregate data and by applying a flexible operational prediction method.},
