Pedestrian flow efficiency and safety are primary requirements in the effective configuration and management of urban gathering spaces, such as railway stations, stadiums, or shopping malls. Moreover, the quality and comfort level of available walking environments play a key role in the challenge of sustainable mobility. As a consequence, there has been growing interest in developing methodologies for analysing the walking transport mode. In this context, the authors deem crucial to build a pedestrian dynamics simulation framework that they can completely control, from the modelling and calibration under different flow conditions to the implementation of a user-friendly tool that allows testing the model in a variety of case studies. In this study, they focus on the implementation and calibration of an agent-based model that microscopically simulates the interactions between individuals and with the environment. They calibrate the model parameters with a behavioural-based approach that relies on observed motion behaviours. Additionally, they present preliminary findings from pedestrian flow experiments performed and monitored with dedicated video recording systems. The collected data are meant to improve the calibration and validate the simulator, but they also provide insights into the emergence of collective behaviours, which can have significant upshots on the theoretical framework.

行人动力学仿真框架：建模和校准

行人流的效率和安全性是对城市聚集空间（如火车站，体育场或购物中心）进行有效配置和管理的主要要求。此外，可用步行环境的质量和舒适度在可持续出行挑战中扮演着关键角色。因此，人们对开发用于分析步行运输方式的方法学的兴趣日益浓厚。在这种情况下，作者认为建立一个行人动力学仿真框架至关重要，他们可以完全控制该模型，从在不同流动条件下的建模和校准，到实施允许在各种案例研究中测试模型的用户友好工具。 。在这个研究中，他们专注于基于代理的模型的实现和校准，该模型可微观地模拟个体之间以及与环境之间的相互作用。他们使用基于行为的方法来校准模型参数，该方法依赖于观察到的运动行为。此外，他们还提供了行人流量实验的初步发现，并通过专用视频记录系统进行了监测。收集的数据旨在改善校准并验证模拟器，但它们还提供了对集体行为出现的见解，这些行为可能会对理论框架产生重大影响。他们介绍了行人流量实验的初步发现，并通过专用视频记录系统进行了监测。收集的数据旨在改善校准并验证模拟器，但它们还提供了对集体行为出现的见解，这些行为可能会对理论框架产生重大影响。他们介绍了行人流量实验的初步发现，并通过专用视频记录系统进行了监测。收集的数据旨在改善校准并验证模拟器，但它们还提供了对集体行为出现的见解，这些行为可能会对理论框架产生重大影响。
