【摘要】：高速鐵路客運(yùn)樞紐站作為多種交通方式相互銜接的基本支撐和大規(guī)�？土鞯募�(chǎng)所,已經(jīng)成為城市客運(yùn)網(wǎng)絡(luò)的重要節(jié)點(diǎn),在城市客運(yùn)交通體系中具有重要的作用和地位。由于樞紐內(nèi)的客流具有很強(qiáng)的聚集性,尤其在高峰時(shí)段,大量的客流遲滯和阻塞很容易造成樞紐站內(nèi)設(shè)施服務(wù)水平的急劇下降和人群擁擠的安全隱患問題。因此,本文依托國(guó)家863課題“高速鐵路綜合客運(yùn)樞紐集散服務(wù)網(wǎng)絡(luò)行人安全狀態(tài)識(shí)別技術(shù)”,在建立樞紐設(shè)施網(wǎng)絡(luò)模型和客流集散仿真模型的基礎(chǔ)上,設(shè)計(jì)開發(fā)了客流集散仿真系統(tǒng),以評(píng)估樞紐在不同客流條件下的集散效果和安全狀態(tài),給出樞紐設(shè)施的服務(wù)水平,為設(shè)施的合理布局設(shè)計(jì)提供依據(jù)。 本文對(duì)樞紐設(shè)施進(jìn)行了系統(tǒng)的研究與分析,從行人的認(rèn)知角度建立了樞紐設(shè)施模型和樞紐網(wǎng)絡(luò)模型。依據(jù)對(duì)行人交通行為的研究與分析,建立了包含客流運(yùn)動(dòng)模型,客流到達(dá)模型,路徑選擇模型和障礙物規(guī)避模型4個(gè)部分的客流集散仿真模型。通過對(duì)基礎(chǔ)社會(huì)力模型的改進(jìn)和優(yōu)化,使模型更加合理的描述集散行為。通過對(duì)模型中涉及到的矢量、標(biāo)量之間運(yùn)算關(guān)系的詳細(xì)論述以及算法流程的優(yōu)化,使集散模型更加適用于系統(tǒng)開發(fā)。 本文以Visual C#語言和SQL server數(shù)據(jù)庫(kù)為開發(fā)工具,以所建立的樞紐設(shè)施網(wǎng)絡(luò)模型和客流集散模型為基礎(chǔ),設(shè)計(jì)并開發(fā)了客流集散仿真系統(tǒng)。仿真系統(tǒng)分為系統(tǒng)管理、數(shù)據(jù)庫(kù)管理、‘仿真環(huán)境搭載、客流屬性設(shè)置、仿真控制、仿真輸出、仿真數(shù)據(jù)分析、客流安全分級(jí)八個(gè)模塊。每個(gè)模塊的功能進(jìn)行了詳細(xì)設(shè)計(jì),并以直觀、便捷的圖形界面交互方式提供給分析者和用戶。以北京南站為例,進(jìn)行了客流集散仿真系統(tǒng)的實(shí)例應(yīng)用研究,驗(yàn)證了集散仿真模型的有效性,給出了不同客流條件下評(píng)估高鐵樞紐集散效率和安全狀態(tài)的方法。
[Abstract]:High speed railway passenger terminal station, as the basic support of various traffic modes and the distributing place of large-scale passenger flow, has become an important node of the urban passenger transport network and plays an important role and position in the urban passenger transport system. Due to the strong aggregation of passenger flow in the hub, especially during the peak hours, the delay and obstruction of a large number of passenger flows can easily lead to a sharp decline in the service level of facilities in the hub station and the safety hidden danger of crowd congestion. Therefore, based on the national 863 project "High-speed railway integrated passenger hub network pedestrian safety status identification technology", based on the establishment of hub facilities network model and passenger flow distribution simulation model, The simulation system of passenger flow distribution is designed and developed to evaluate the distribution effect and security state of the hub under different passenger flow conditions, to provide the service level of the hub facilities, and to provide the basis for the reasonable layout and design of the facilities. In this paper, the hub facilities are systematically studied and analyzed, and the hub facilities model and the hub network model are established from the perspective of pedestrian cognition. Based on the research and analysis of pedestrian traffic behavior, a passenger flow distribution simulation model including passenger flow movement model, passenger flow arrival model, path selection model and obstacle avoidance model is established. Through the improvement and optimization of the basic social force model, the distributed behavior can be described more reasonably. The distributed model is more suitable for system development through the detailed discussion of the vectors involved in the model, the operation relationship between scalars and the optimization of the algorithm flow. Based on Visual C # language and SQL server database, based on the network model of hub facilities and passenger flow distribution model, a passenger flow distribution simulation system is designed and developed in this paper. The simulation system is divided into eight modules: system management, database management simulation environment, passenger flow attribute setting, simulation control, simulation output, simulation data analysis and passenger flow security classification. The function of each module is designed in detail, and it is provided to analysts and users in an intuitive and convenient way. Taking Beijing South Railway Station as an example, the application research of passenger flow distribution simulation system is carried out, which verifies the validity of the distributed simulation model, and gives a method to evaluate the efficiency and safety state of high-speed rail hub under different passenger flow conditions.
