Abstract:

To deal with the elastic intercity travel demand of the passenger, the optimization of the compined decisionmaking involving the bus operating frequency and the ticket price of the passenger transport enterprise was studied. Comprehensively considering the passenger travel time adjustment cost, inbus congestion cost, travel ticket cost, as well as the fied cost, variable cost, and the allocated cost of the road construction and maintenance, an optimization model to maximize the total income of the passengers and the enterprise was established and its solving method was proposed.As an example, the travel time adjustment cost function of a special group of passengers was discussed in detail and numerically analyzed. The suggested optimization provides a theoretical foundation for the combined decisionmaking on the bus operating frequency and the ticket price.
