摘要
增建可靠、实用、经济、便捷的停车库是破解城市建成区停车难问题的一项基本措施。针对停车困难区域,设计了2种建筑式立体车库方案,并给出了经济性指标。运用MATLAB编程模拟汽车电梯的运行模式,计算了在存车优先、取车优先、原地待命3种策略下,立体车库配备1,2,3部汽车电梯时的工作速率,并给出了最佳的运行策略。通过对某居民小区的车流资料和MATLAB模拟得到的汽车电梯运行时间进行分析,得出车流和汽车电梯运行时间的概率分布形式。基于排队论,结合车流的概率分布形式、在最优策略下立体车库的工作速率及用户可接受的等待时间,确定了本研究立体车库方案的汽车电梯最优配备数量。研究结果表明:车库在应对连续车流时,原地待命策略是最佳的运行策略;立体车库在最佳策略下,应对该地车流时,配备2部汽车电梯即可满足用户的存取车需求;排队系统的平均队长、平均排队长、平均逗留时间和平均等待时间4个参数也在可接受范围内。
Building reliable,practical,economical and convenient parking garages is a basic measure to solve the problem of difficult parking in some built-up areas in cities.Two kinds of building stereo garage design schemes were proposed and their economic indicators were given.The operation modes of the car elevators were simulated by MATLAB programming,the working rate of the stereo garage with 1,2 and 3 car elevators under three different strategies including storage priority,picking-up priority and standing-by was calculated,and the optimal operation strategy was given.Through the analysis of the traffic flow data of a residential area and the running time of the car elevator from the MATLAB programming simulation,the probability distribution form of the traffic flow and the running time of the car elevator was obtained.Based on the queuing theory,combined with the probability distribution form of the traffic flow,the working speed of the stereo garage under the o ptimal control strategy and the users'acceptable waiting time,the optimal number of car elevators for the stereo garage scheme was determined.The research results show that when the garage is dealing with continuous traffic,the standing-by strategy is the optimal operation strategy.When responding to the local traffic flow under the optimal operation strategy,the configuration of two car elevators can meet the need of users to access the cars and the four p arameters of the average queue length,average queuing platoon,average length of stay,average waiting time of the queuing system are also acceptable.
