出租车上客区规模的Monte Carlo仿真计算方法

为确定出租车上客区的合理规模，分析其运行特征，同时存在乘客和出租车相互等待的情况，而不能采用停车场模型或排队论模型计算。采用Monte Carlo仿真方法，利用随机原理来拟合乘客与出租车的相互作用过程，给出了合理规模的确定流程。实例应用证明该方法具有很好的适用性;同时分析结果表明：（1）当出租车上客区泊位规模达到一定程度时，再增加并不能减少乘客等待时间;（2）高峰时段适当限制乘客的排队长度能够在较小比例的乘客损失下，极大地降低乘客的等待时间。

Monte Carlo simulation calculation method for taxi boarding area scale

To determine the reasonable scale of the taxi boarding area,this paper analyzes the operating characteristics that the passengers and unoccupied taxies may waiting,which can not be calculated with parking model or queue theory model. Therefore,it adopts the random data to fitting the interaction process between the passengers and taxis with Monte Carlo simulation.The numerical example validates the applicability of the mode and shows that：（1）the queue waiting time will not reduce after the berths of the taxi boarding areas reached the certain nember;（2）it can greatly reduce the average waiting time when queue length is restricted.
