In this research, establish the queuing pricing policy that will eliminate or reduce queuing time and disperse all trampers’ arrival times to achieve equilibrium. In the current literatures of queuing pricing model for tramper, length of queuing time is the crucial key point to calculate the equilibrium cost and derive the toll structure. However, these literatures, assume trampers arrival to the port for Poisson distribution. We use Poisson distribution to calculate expected value of vessels for trampers, however expected value of vessels could change as digit of decimal point. In this research use 95% confidence interval to solve this error, in order to improve the model for practice. In addition to this, trampers are successively arriving to the port that will generate headway times and affect queuing time. In this article use Exponential distribution to calculate headway times, in order to the model for accurate. Based on trampers queuing time model to derive the equilibrium cost, and then construction a series of queuing toll scheme including non-queuing toll scheme and optimal toll scheme. Analysis equilibrium arrival rate, schedule delay cost and result of dispersing arrival time for trampers after implementing toll collection. Lastly, according to the data from Taiwan Kaohsiung International Port Corporation, Ltd to verification model. The above descriptions have not yet been concerned with the current literatures. The fruitful results of this research will be expectable to make the queuing theory become more complete and practical.
