【摘要】:隨著城市停車問題矛盾突出,用地緊張,立體車庫是緩解城市停車難問題的有效途徑,立體車庫占地少,空間利用率高。但是由于目前立體車庫的規(guī)劃不合理的問題,有些立體車庫存取效率低下,立體車庫建設(shè)以后使用率低,不能發(fā)揮其應(yīng)有的作用并造成嚴(yán)重的資源浪費,因此合理規(guī)劃立體車庫的規(guī)模和優(yōu)化立體車庫車輛的存取速度尤為重要。本文基于排隊論理論,構(gòu)建了一套完整的規(guī)劃立體車庫規(guī)模的模型,并提出了一種優(yōu)化車輛存取速度的方法。本文分析了目前不同類型立體車庫的優(yōu)缺點和適用性,選取巷道堆垛式立體車庫作為本文的研究對象。首先從微觀角度對立體車庫車輛的?窟^程進行了分析,得出立體車庫排隊過程分為等待空車位和等待堆垛機兩個階段。然后對影響立體規(guī)模的各個因素進行了分析總結(jié)。其次通過對調(diào)查數(shù)據(jù)進行分析,得出車輛到達分布符合泊松分布,車輛停車時長分布符合愛爾朗分布。在上述分析基礎(chǔ)上,基于排隊論理論建立了立體車庫規(guī)模模型,根據(jù)系統(tǒng)達到平衡狀態(tài)下的車輛被拒絕概率來確定合理的車庫泊位數(shù),并建立了考慮成本的情況下立體車庫規(guī)模模型。然后在確定的車庫規(guī)模的情況下,對影響立體車庫存取規(guī)模的因素進行了分析,并建立了參考傾向選擇性系數(shù)的堆垛機數(shù)量模型。考慮不同客戶的容忍度構(gòu)建了優(yōu)化模型。通過選取不同的堆垛機數(shù)量和不同的配置速度計算分析,對立體車庫的車輛存取速度進行了優(yōu)化。最后選取佛山創(chuàng)意產(chǎn)業(yè)園實例進行了仿真分析驗證,首先分析了園區(qū)基本停車情況,然后根據(jù)調(diào)研所得數(shù)據(jù)對停車基本特性進行了分析,根據(jù)前文所建模型進行了計算,得出所需基本停車位和出入口數(shù)量,并通過建立了 VISSIM仿真模型,對比計算與仿真結(jié)果,驗證了所建模型的有效性。
[Abstract]:With the contradiction of parking problem in the city is prominent and the land is tight, the three-dimensional garage is an effective way to alleviate the difficult problem of parking in the city. The three-dimensional garage occupies less land, and the space utilization ratio is high. However, due to the unreasonable planning of the three-dimensional garage at present, Some stereoscopic garages have low access efficiency and low utilization rate after the construction of stereoscopic garages, which can not play their due role and cause serious waste of resources. Therefore, it is very important to plan the scale of stereoscopic garage and optimize the access speed of the vehicle. Based on the theory of queuing theory, this paper constructs a complete model for planning the scale of stereoscopic garage. A method of optimizing vehicle access speed is proposed. The advantages and disadvantages and applicability of different types of stereoscopic garages are analyzed in this paper. This paper selects the roadway stacking stereoscopic garage as the research object. Firstly, the parking process of the stereoscopic garage vehicle is analyzed from the microscopic point of view. It is concluded that the queuing process is divided into two stages: waiting empty parking space and waiting stacker. Then, the factors affecting the three-dimensional scale are analyzed and summarized. Secondly, the investigation data are analyzed. It is concluded that the vehicle arrival distribution accords with Poisson distribution, and the vehicle parking time distribution accords with Allan distribution. Based on the above analysis, a three-dimensional garage scale model is established based on the queuing theory. According to the rejection probability of the vehicle in equilibrium state, the reasonable parking space number is determined, and the model of three-dimensional garage size is established considering the cost. Then, in the case of determining the garage size, This paper analyzes the factors that affect the access scale of stereoscopic garage. The model of the quantity of stacker with reference selectivity coefficient is established, and the optimization model is constructed considering the tolerance of different customers. By selecting different quantity of stacker and different configuration speed, the model is calculated and analyzed. The vehicle access speed of the three-dimensional garage is optimized. Finally, the example of Foshan creative industry park is selected for simulation analysis and verification. Firstly, the basic parking situation of the park is analyzed. Then, the basic characteristics of parking are analyzed according to the data obtained from the investigation, and the basic parking spaces and the number of entrances and exits are calculated according to the previous model, and the VISSIM simulation model is established, and the results are compared with the simulation results. The validity of the model is verified.
