交通枢纽乘客交互作用建模与仿真

Modeling and Simulation of Passenger Interactions in Transport Hubs

从交通枢纽乘客行为的环境影响因素与交互作用出发,建立了面向枢纽复杂环境的乘客交互作用仿真模型。通过探究乘客自组织特性的生成机理,该模型引入环境势能场和个体势能场的概念与方法,提出乘客潜在交互作用模拟的解决方法,能够有效捕捉乘客行为特性,再现乘客在复杂环境中的决策行为。以走廊单/双向乘客流与瓶颈通过场景为实例,应用计算机仿真试验对模型进行了校验。

Based on the environment and interactions of passengers of transport hubs,a simulation model for passenger interactions was proposed. According to the study of mechanism of passenger self-organization,the model introduced concept of environment potential field and individual potential field,and provided an access to the modeling of passenger potential interactions. The model was effective in capturing and generating of the decision making behavior in complicated environment with high density of passengers. Unidirectional / bidirectional passengers movement and passengers movement through a bottleneck were selected as cases. Simulation experiments run for the verification and validation of the model.
