【摘要】：高速铁路客运枢纽站作为多种交通方式相互衔接的基本支撑和大规模客流的集散场所,已经成为城市客运网络的重要节点,在城市客运交通体系中具有重要的作用和地位。由于枢纽内的客流具有很强的聚集性,尤其在高峰时段,大量的客流迟滞和阻塞很容易造成枢纽站内设施服务水平的急剧下降和人群拥挤的安全隐患问题。因此,本文依托国家863课题“高速铁路综合客运枢纽集散服务网络行人安全状态识别技术”,在建立枢纽设施网络模型和客流集散仿真模型的基础上,设计开发了客流集散仿真系统,以评估枢纽在不同客流条件下的集散效果和安全状态,给出枢纽设施的服务水平,为设施的合理布局设计提供依据。本文对枢纽设施进行了系统的研究与分析,从行人的认知角度建立了枢纽设施模型和枢纽网络模型。依据对行人交通行为的研究与分析,建立了包含客流运动模型,客流到达模型,路径选择模型和障碍物规避模型4个部分的客流集散仿真模型。通过对基础社会力模型的改进和优化,使模型更加合理的描述集散行为。通过对模型中涉及到的矢量、标量之间运算关系的详细论述以及算法流程的优化,使集散模型更加适用于系统开发。本文以Visual C#语言和SQL server数据库为开发工具,以所建立的枢纽设施网络模型和客流集散模型为基础,设计并开发了客流集散仿真系统。仿真系统分为系统管理、数据库管理、‘仿真环境搭载、客流属性设置、仿真控制、仿真输出、仿真数据分析、客流安全分级八个模块。每个模块的功能进行了详细设计,并以直观、便捷的图形界面交互方式提供给分析者和用户。以北京南站为例,进行了客流集散仿真系统的实例应用研究,验证了集散仿真模型的有效性,给出了不同客流条件下评估高铁枢纽集散效率和安全状态的方法。
[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.
