  To analyze the influence of introducing the High-Speed Railway (HSR) system
on business and non-business travel behavior, this study develops an integrated
inter-city travel demand model to represent trip generations, destination
choice, and travel mode choice behavior. The accessibility calculated from the
RP/SP (Revealed Preference/Stated Preference) combined nested logit model of
destination and mode choices is used as an explanatory variable in the trip
frequency models. One of the important findings is that additional travel would
be induced by introducing HSR. Our simulation analyses also reveal that HSR and
conventional airlines will be the main modes for middle distances and long
distances, respectively. The development of zones may highly influence the
destination choices for business purposes, while prices of HSR and Low-Cost
Carriers affect choices for non-business purposes. Finally, the research
reveals that people on non-business trips are more sensitive to changes in
travel time, travel cost and regional attributes than people on business trips.
