基于排队论的单车道出租车上客系统建模与仿真

Modeling and Simulation of Single Lane Taxi Boarding System Based on Queuing Theory

对单车道离港出租车上客系统通行能力的影响因素进行了仿真研究,将车辆放行控制员和乘客放行控制员的行为规则定义为逻辑开关对象,基于GPSS语言实现了车辆产生、车辆允许驶入、乘客上车、车辆驶出等过程的业务逻辑,并基于录像资料对上述过程所耗费的时间进行了统计和拟合分析,然后基于仿真模型进行了多轮仿真实验。得出以下两条结论:1.泊位数量增加与通行能力增长之间的定量关系;2.配备服务人员帮助携带大件行李的旅客上车,通行能力可提高15%左右。

Taxi pick-up area was described as a queuing system based on the GPSS language to establish a simulation model, to find out a new way to improve taxi traffic capacity. Vehicle release officer and passenger release officer were represented by logic switch object, such business logic as taxi producing, taxi entering, boarding, taxi leaving could be reappeared well in computer. The time which spent on the above processes were analysed and by video data. Multi wheel simulation experiments were carried ont. Quantitative analysis was executed to find out how the traffic capacity are affected by the berth quantity and the fluctuation of boarding time. Two conclusions were drawn through simulation experiments ： 1. Quantitative relation between berth quantity and system capacity. 2. Equipped with waiters to help carry bulky luggage passengers could improve traffic capacity 15%.
