Abstract
This paper formulates a model to explore market shares of intercity modes including automobile highway (AH), high-speed rail(HSR) and air transport(AT).The relationship among demand-supply attributes such as fare,speed,terminal locations,travelers' trip length,the value of time,departure time and origin and destination locations is explored to identify market boundaries by comparing different routing strategies for each type of passenger.Passengers' optimal choices are assumed by minimizing their generalized travel time and then are aggregated by accumulating a probability density function of value of time and time zones with the same waiting time differences.The results show that passengers with higher value of time tend to choose the mode with less travel time but higher cost. And how demand-supply attributes such as the number of persons in one car, access time to HSR station, and HSR fare impact market share distribution among three modes.
