Abstract: The passengers transfer time in urban transportation terminal can be divided into three parts:walk time,queue delay time and the time wait for bus.The queue delay time is an important index in weighing for the continuity of transfer,adaptability of equipment and so on.Analyses the character of passengers in ticket queue,and get the average server time though the actual data.Then define the queue system in terminal is an M/G/K queue that be composed by several kinds of passengers.Analyze the superposition of Poisson demand arrival processes;finally get the expressions of average delay time.Get an actual result by this expression of XiZhiMen transportation terminal.
