【摘要】：隨著人均汽車保有量的快速增長,城市停車需求急劇增長,停車供需矛盾日益突出,導(dǎo)致這種問題出現(xiàn)的一部分原因就是在既有交通設(shè)施供給的條件下,停車設(shè)施的功能沒有得到充分發(fā)揮。因此,本文從停車設(shè)施供需問題中的“供”入手,對路外停車場的交通優(yōu)化組織方法及其仿真評價進(jìn)行了研究,以期能高效發(fā)揮既有設(shè)施功能,提高其利用率,降低對周圍交通的干擾。論文的主要工作如下:首先,參考國內(nèi)外對路外公共停車場的研究現(xiàn)狀,詳細(xì)分析了停車場的停車特點及出入口交通運行基本特性,得出停車場交通與城市路段交通聯(lián)系的基本規(guī)律。其次,通過分析交通組織范圍的影響因素,確定了路外公共停車場的交通組織范圍,并分別從以下幾個方面進(jìn)行了停車場交通組織優(yōu)化研究:①采用排隊論和幾何視距三角形法分別對三種典型的路外公共停車場出入口長度進(jìn)行了優(yōu)化設(shè)計;②分別從功能單一的出口之間的間距和用標(biāo)線分隔的出入口之間的間距兩個方面對超過一定規(guī)模的大型停車場出入口理論間距進(jìn)行確定;③對停車場內(nèi)部交通組織、外部的車流組織、誘導(dǎo)設(shè)施的布設(shè)等進(jìn)行了不同方面的優(yōu)化。然后,通過分析停車場出入口和交通組織方面的相互關(guān)系,在考慮停車場交通系統(tǒng)受多種因素影響的基礎(chǔ)上結(jié)合vissim仿真軟件的評價指標(biāo),構(gòu)建了出入口交通組織優(yōu)化評價指標(biāo)體系;利用定量定性分析相結(jié)合的方法,將信息熵、隸屬函數(shù)、復(fù)合物元有機地結(jié)合起來,建立了基于模糊復(fù)合物元的停車場出入口交通組織方案綜合評價模型。最后,以蘭州市安寧區(qū)的停車場為例,通過問卷調(diào)查和觀測記錄方法對其路外公共停車場進(jìn)行了相關(guān)調(diào)查和分析;在此基礎(chǔ)上,選擇了3個出入口與不同等級道路銜接的停車場進(jìn)行了出入口長度、出入口間距計算,并進(jìn)行了其它方面的優(yōu)化;結(jié)合vissim交通仿真軟件對模型進(jìn)行了驗證,并對建立在不同等級道路的停車場優(yōu)化方案運用所構(gòu)建的物元評價模型進(jìn)行了評價,用定量的數(shù)值表達(dá)了停車場交通組織方案的評價結(jié)果。結(jié)果表明:所采取的優(yōu)化措施在不同等級的道路上都會取得一定的效果,均停車延誤有明顯的降低,并且在主干路上運用時取得的效果最明顯。這說明改進(jìn)停車場的出入口長度、出入口間距對于提高停車場的利用率,降低周圍交通的干擾有一定的作用。
[Abstract]:With the rapid growth of per capita car ownership, the urban parking demand increases sharply, and the contradiction between supply and demand of parking becomes more and more prominent. Part of the reason for this problem is under the condition of the existing transportation facilities. The function of parking facilities has not been given full play. Therefore, this paper starts with the "supply" of parking facilities supply and demand, and studies the traffic optimization organization method and its simulation evaluation of off-road parking lot. The main work of this paper is as follows: first of all, referring to the research status of the public parking lot outside the road at home and abroad. The parking characteristics of the parking lot and the basic characteristics of the entrance and exit traffic operation are analyzed in detail, and the basic law of the connection between the parking lot traffic and the urban section traffic is obtained. Secondly, the factors affecting the traffic organization range are analyzed. The traffic organization of the off-road public car park is determined. And from the following several aspects of the parking lot traffic organization optimization research: 1 using the queuing theory and geometric horizon triangle method to three typical off-road public parking entrance length optimization design; (2) to determine the theoretical distance between the entrance and exit of a large parking lot over a certain scale from two aspects: the distance between the single function exits and the distance between the entrance and exit separated by the mark line; (3) the internal traffic organization, the external traffic organization and the layout of the induced facilities are optimized in different aspects. Then, the relationship between the entrance and exit of parking lot and traffic organization is analyzed. On the basis of considering the influence of many factors on the traffic system of parking lot, combined with the evaluation index of vissim simulation software, the evaluation index system of traffic organization optimization of entrance and exit is constructed. Using the method of quantitative qualitative analysis, the information entropy, membership function and complex elements are organically combined. A comprehensive evaluation model of the traffic organization scheme of the parking lot entrance and exit based on fuzzy complex element is established. Finally, the parking lot in Anning District of Lanzhou City is taken as an example. By means of questionnaire survey and observation record, the author has carried on the related investigation and analysis to the public parking lot outside the road. On this basis, three entrances connecting with different grade roads are selected to calculate the length of the entrance and the distance between the entrances and exits, and other aspects of optimization are carried out. The model is validated with vissim traffic simulation software, and the matter element evaluation model based on the optimization scheme of different grade roads is evaluated. The evaluation results of traffic organization scheme of parking lot are expressed by quantitative numerical value. The results show that the optimized measures can achieve certain results in different grades of roads, and the delay of parking is obviously reduced. It shows that improving the length of the entrance and exit and the distance between the entrances and exits can improve the utilization rate of the parking lot and reduce the disturbance of the surrounding traffic.
