Abstract: The characteristics of a highway passenger transportation terminal system are analyzed. By employing the simulation optimization theory and method, the operation simulation framework of the system is constructed; the simulation programthat has been confirmed effective iswritten; and thewhole process of operation of the system is reappeared. Through the computer simulation, the rationality of the station-yard layoutof passengertransportation systems can be evaluated, thus affording a scientific basis forthe passenger station-yard programming. For the present station-yard systems, the operation plans possible to be adopted can be previewed, so that the traffic organization plans can be optimized. A simulation example is also presented.
