摘　　要：近年来,建设机械式停车场逐步成为解决停车难问题的一大举措。如何保证机械式停车库的运行效率是建设机械式停车库首要考虑的问题。文章通过对武汉市同济医院一个月停车数据的分析,对车辆到达分布通过假设检验的方式证明高峰时段内单位时间间隔到达同济医院的车辆数是服从参数为l的泊松分布,并应用排队论模型对同济医院高峰时段排队指标进行分析,得出同济医院机械式停车库规模:包括升降机台数和机械式停车库的泊位规模,为提高停车服务效率和优化停车设施配置提供决策依据。文章中所述机械车库类型为平面移动类。The construction of mechanical parking system has gradually become a solution to the parking problem in recent years. How to ensure the operating efficiency of the mechanical parking system is the primary consideration. Based on the analysis of one-month parking data of Tongji Hospital in Wuhan City, the paper proves that the number of vehicles arriving in Tongji Hospital at the peak period follows the Poisson distribution with the parameter l by means of a hypothesis test and queuing theory is used to analyze the queuing index of Tongji hospital during peak hours. The analysis results in the mechanical parking scale including the numbers of both the lift and parking space which provides the basis for improving the efficiency of parking service and optimizing the configuration of parking facilities. The type of mechanical parking system in this paper is horizontal shifting mechanical parking system.
