【摘要】：城市軌道交通是解決城市交通問題的重要方式,近年來取得了較快的發(fā)展,已成為區(qū)域一體化交通網(wǎng)絡(luò)的組成部分,實現(xiàn)了城市客流的迅速集散與換乘,提高了城市交通網(wǎng)絡(luò)的整體運行效率、服務(wù)水平。但由于城市軌道交通運量增長過快,城市軌道交通樞紐的通道、樓梯、節(jié)點等基礎(chǔ)設(shè)施設(shè)計考慮的欠缺,出現(xiàn)了城市軌道交通樞紐行人流線混亂,換乘距離過長等現(xiàn)象,影響了樞紐的運營效率。因此對行人動態(tài)行為特征與樞紐設(shè)施的適應(yīng)性進行研究,歸納行人在樞紐內(nèi)的行為規(guī)律,并以此為根據(jù)進行樞紐流線優(yōu)化,有助于縮短行人的出行時間,提高樞紐的運營效率。 本文以城市軌道交通樞紐流線費用為研究對象,根據(jù)行人在樞紐內(nèi)的行為特征,研究行人通過不同基礎(chǔ)設(shè)施時所需要的時間。將通過通道、步行樓梯、自動扶梯等設(shè)施的時間定義為路段費用,通過通道交叉點、客流集散點等處的時間定義為節(jié)點費用,根據(jù)行人在樞紐內(nèi)的走行特征,分別建立了路段費用和節(jié)點費用模型。論文主要做了以下工作： (1)對比分析城市軌道交通樞紐交通調(diào)查方法的優(yōu)缺點及適應(yīng)性,采用人工跟隨調(diào)查的方法,對北京地鐵西直門站進行了交通調(diào)查,并根據(jù)調(diào)查數(shù)據(jù),建立了以BPR函數(shù)為基礎(chǔ)的樞紐內(nèi)行人路段費用模型。 (2)對比分析主要行人微觀仿真模型的特點,選取基于社會力模型的Anylogic軟件對樞紐節(jié)點進行仿真。通過對行人的微觀行為多個方案的仿真,利用統(tǒng)計學(xué)原理,分析行人宏觀交通流特性。根據(jù)交通組織形式的不同,將產(chǎn)生流線相交的樞紐節(jié)點分成3類7種,分別對每種樞紐節(jié)點組織形式進行仿真,得出行人在不同節(jié)點組織形式的下通行能力、節(jié)點延誤及走行時間規(guī)律,以此為基礎(chǔ)建立樞紐內(nèi)的節(jié)點費用模型。 (3)將路段費用模型與節(jié)點費模型應(yīng)用于城市軌道交通樞紐流線優(yōu)化模型中,并以某市地鐵換乘站為例,對模型進行了算例驗證,驗證了費用模型的有效性。
[Abstract]:Urban rail transit is an important way to solve urban traffic problems. It has made rapid development in recent years and has become a part of regional integrated transportation network. It has realized the rapid distribution and transfer of urban passenger flow. The whole operation efficiency and service level of urban transportation network are improved. However, due to the rapid growth of urban rail transit volume and the lack of consideration in the design of infrastructure such as corridors, staircases and nodes of urban rail transit hubs, the pedestrian flow lines of urban rail transit hubs are chaotic, and the transfer distance is too long. Affected the operational efficiency of the hub. Therefore, the characteristics of pedestrian dynamic behavior and the adaptability of the hub facilities are studied, and the pedestrian behavior in the hub is summarized, and based on this, the optimization of the hub streamline is helpful to shorten the pedestrian travel time and improve the operational efficiency of the hub. In this paper, based on the characteristics of pedestrian behavior in urban rail transit hub, the time required for pedestrians to pass through different infrastructure is studied. The time of passage, walking stairs, escalators and other facilities is defined as the link cost, and the time of passing through the crossing point, the passenger flow distribution point, etc., is defined as the node cost, according to the pedestrian travel characteristics in the hub, The model of link cost and node cost are established respectively. The main work of this paper is as follows: (1) comparing and analyzing the advantages and disadvantages and adaptability of urban rail transit hub traffic survey methods, using the method of artificial follow investigation, the Beijing Metro Xizhimen Station traffic survey, Based on the investigation data, the cost model of pedestrian section is established based on BPR function. (2) comparing and analyzing the characteristics of the main pedestrian micro simulation model, Anylogic software based on social force model is selected to simulate the hub node. Based on the simulation of several schemes of pedestrian's microscopic behavior, the characteristics of pedestrian's macroscopic traffic flow are analyzed by using the principle of statistics. According to the different forms of traffic organization, the junction nodes that produce streamline intersection are divided into 3 types and 7 types, and each kind of node organization is simulated, and the capacity of pedestrians under different node organization forms is obtained. Based on the rules of node delay and travel time, the node cost model in the hub is established. (3) the section cost model and the node fee model are applied to the streamline optimization model of the urban rail transit hub, and the example of a city subway transfer station is given to verify the validity of the cost model.
