Railway passengers travel behavior based on bounded rationality by rough set weight

Pointing at the bounded rationality problem of passenger travel choice in the railway corridor, this paper proposes a travel choice theory considering passengers psychological expectation, and establishes the travel mode decision model based on prospect theory. With the comprehensive prospect value combined by analyzing the travel time, travel expenses and the comfort degree of the psychological reference point, it obtains the passengers travel mode choice results. Taking railway transport corridor from Baoji to Lanzhou as an example, by calculating the comprehensive prospect value, and analyzing the punctuality, the scheduled arrival time, price and the sensitivity from speed on travel choice, it finds out that the passengers tend to choose high-speed rail travel with a higher punctuality rate and tend to a mode with relatively lower fares and faster speed. When the predetermined arrival time is abundant, the travel proportion of choosing the general rail travel with longer travel time and better economy is gradually increasing.
