This study incorporates intercity travelers' mode choice as well as route choices into a framework by exploring the relationship among key demand and supply variables. Travelers' optimal mode and route choices along a corridor with air transportation (AT), high-speed rail (HSR) and automobiles are assumed by minimizing their generalized travel time including travel time and cost time, which is transferred from travel monetary cost via the value of time. Travel time is defined as including waiting time at stations, riding time, access time and egress time, while travel monetary cost is composed of fare and access/egress cost. The optimal alternative is explored by comparing, respectively, differences in travel time and in cost time between two alternatives. A case study is presented to demonstrate the application of the model. The results show that travelers with the higher values of time tend to choose faster modes as their intercity modes, which are combined with progressive or backtracking taxis to the final destinations. The results also show regardless of trip distance, the tendency towards using automobiles to complete the entire trip is higher for those with the lower values of time.
