Understanding influences on pedestrian movement is important to accurately simulate crowd behaviour, yet little research has explored the psychological factors that influence interactions between large groups in counterflow scenarios. Research from social psychology has demonstrated that social identities can influence the micro-level pedestrian movement of a psychological crowd, yet this has not been extended to explore behaviour when two large psychological groups are co-present. This study investigates how the presence of large groups with different social identities can affect pedestrian behaviour when walking in counterflow. Participants (N = 54) were divided into two groups and primed to have identities as either ‘team A’ or ‘team B’. The trajectories of all participants were tracked to compare the movement of team A when walking alone to when walking in counterflow with team B, based on their i) speed of movement and distance walked, and ii) proximity between participants. In comparison to walking alone, the presence of another group influenced team A to collectively self-organise to reduce their speed and distance walked in order to walk closely together with ingroup members. We discuss the importance of incorporating social identities into pedestrian group dynamics for empirically validated simulations of counterflow scenarios.
了解对行人运动的影响对于准确模拟人群行为很重要,但很少有研究探讨在逆流场景中影响大型群体之间互动的心理因素。社会心理学的研究表明,社会身份可以影响心理人群的微观行人运动,但这还没有扩展到探索两个大型心理群体共同存在时的行为。这项研究调查了具有不同社会身份的大型群体在逆流中行走时如何影响行人行为。参与者(N=54)被分为两组,并被要求具有“A队”或“B队”的身份。根据所有参与者的i)运动速度和行走距离,以及ii)参与者之间的距离,跟踪所有参与者的轨迹,以比较A队单独行走时与B队逆流行走时的运动。与单独行走相比,另一组的存在影响了团队A集体自我组织,以降低他们的行走速度和距离,从而与团队成员紧密地一起行走。我们讨论了将社会身份纳入行人群体动力学的重要性,以进行逆流情景的实证验证模拟。

Statistical Model Fitting and Model Selection in Pedestrian Dynamics Research 行人动力学研究中的统计模型拟合与模型选择
Pub Date : 2019-04-18 DOI: 10.17815/CD.2019.20

Pedestrian dynamics is concerned with understanding the movement patterns that arise in places where more than one person walks. Relating theoretical models to data is a crucial goal of research in this field. Statistical model fitting and model selection are a suitable approach to this problem and here we review the concepts and literature related to this methodology in the context of pedestrian dynamics. The central tenet of statistical modelling is to describe the relationship between different variables by using probability distributions. Rather than providing a critique of existing methodology or a "how to" guide for such an established research technique, our review aims to highlight broad concepts, different uses, best practices, challenges and opportunities with a focussed view on theoretical models for pedestrian behaviour. This contribution is aimed at researchers in pedestrian dynamics who want to carefully analyse data, relate a theoretical model to data, or compare the relative quality of several theoretical models. The survey of the literature we present provides many methodological starting points and we suggest that the particular challenges to statistical modelling in pedestrian dynamics make this an inherently interesting field of research.
行人动力学关注的是了解在多人行走的地方出现的运动模式。将理论模型与数据联系起来是该领域研究的一个重要目标。统计模型拟合和模型选择是解决这一问题的合适方法,在此我们回顾了行人动力学背景下与该方法相关的概念和文献。统计建模的核心原则是通过使用概率分布来描述不同变量之间的关系。我们的综述旨在强调广泛的概念、不同的用途、最佳实践、挑战和机遇,重点关注行人行为的理论模型,而不是对现有方法进行批判或为这种既定的研究技术提供“如何”指南。这篇文章针对的是行人动力学研究人员,他们希望仔细分析数据,将理论模型与数据联系起来,或比较几个理论模型的相对质量。我们对文献的调查提供了许多方法学的起点,我们认为行人动力学统计建模的特殊挑战使这成为一个固有的有趣研究领域。

This article presents a glossary of terms that are frequently used in research on human crowds. This topic is inherently multidisciplinary as it includes work in and across computer science, engineering, mathematics, physics, psychology and social science, for example. We do not view the glossary presented here as a collection of finalised and formal definitions. Instead, we suggest it is a snapshot of current views and the starting point of an ongoing process that we hope will be useful in providing some guidance on the use of terminology to develop a mutual understanding across disciplines. The glossary was developed collaboratively during a multidisciplinary meeting. We deliberately allow several definitions of terms, to reflect the confluence of disciplines in the field. This also reflects the fact not all contributors necessarily agree with all definitions in this glossary. 
本文介绍了在人类群体研究中经常使用的术语表。这个主题本质上是多学科的,因为它包括计算机科学、工程、数学、物理、心理学和社会科学等领域的工作。我们不认为这里提供的术语表是最终和正式定义的集合。相反,我们认为它是当前观点的一个快照,也是一个正在进行的过程的起点,我们希望它将有助于为术语的使用提供一些指导,以发展跨学科的相互理解。该术语表是在多学科会议期间协作开发的。我们故意允许几个术语的定义,以反映学科在该领域的融合。这也反映了并非所有贡献者都同意本术语表中的所有定义。

Characteristics of Stop and Go Wave in One Dimensional Interrupted Pedestrian Flow Through Narrow Channel 窄通道一维断续行人流中走走停停波的特征

Pedestrian microscopic simulation models can aid crowd management only if they can reproduce the crowd behavior correctly. To calibrate and validate the model, it is important to understand crowd movement during various activities involved in mass gathering events. A common practice in such gathering is to hold attendees in waiting area in near corridors separated by crowd barriers before the event and allow entering the event only after a designated time. The crowd is released in small batches to avoid overcrowding inside. Long waiting hours, anger, excitement, competitive feeling etc. can make crowd aggressive during such entries. Crowd flow characteristics due to such behavior is difficult to recreate in pedestrian experimental studies in laboratory setting. This paper studied interrupted flow of such crowd through a narrow corridors made of strong railing channel inside a temple. Interrupted flow lead to formation of one dimensional stop and go waves. These stop and go waves were studied from the trajectory data. The average speed of waves propagating over longer distance were also estimated. The quantitative output from this study can be used to calibrate and validate simulation models of such activity during mass gathering events.
行人微观模拟模型只有能够正确再现人群行为,才能帮助人群管理。为了校准和验证该模型,了解大规模聚集事件中各种活动期间的人群运动是很重要的。这种聚会的一种常见做法是在活动前将与会者安排在由人群屏障隔开的走廊附近的等候区,并只允许在指定时间后进入活动。人群被小批量释放,以避免里面人满为患。漫长的等待时间、愤怒、兴奋、竞争情绪等都会使观众在此类比赛中表现出攻击性。在实验室环境中的行人实验研究中,由于这种行为而产生的人群流动特征很难重现。本文研究了这类人群在寺庙内由坚固的栏杆通道组成的狭窄走廊中的断续流动。中断的流动导致一维走走停停波的形成。这些走走停停的波是从轨迹数据中研究出来的。还估算了波浪在较长距离上传播的平均速度。这项研究的定量输出可用于校准和验证大规模聚集事件期间此类活动的模拟模型。

Understanding movement in heterogeneous groups is important for a meaningful evaluation of evacuation prediction and for a proper design of buildings. The understanding of interactions and influencing factors in heterogeneous groups on key performance figures is fundamental for a safe design. This contribution presents results of experimental studies on movement of a crowd through a bottleneck involving participants with and without disabilities. High precise trajectories of the attendees extracted from video recordings were used to calculate density and velocity of the participants. Besides the well-established fundamental diagram new insights into the individual relation between density and velocity are discussed. A complex structure and considerate behaviour in movement implicates a strong influence of the heterogeneity on key performance values of safe movement.

Crowding and Queuing in Entrance Scenarios: Influence of Corridor Width in Front of Bottlenecks 入口场景的拥挤与排队:瓶颈前通道宽度的影响

In this paper, we present results of an entrance experiment investigating the effect of the corridor width in front of a bottleneck on the density. The idea is based on a previous study suggesting that a guiding system in front of an entrance can reduce pushing of the waiting people and thus the density at the entrance. In our study we aim to find out to what extend the corridor width has an impact on crowding or queuing behavior and with that on the density. The results of the presented experiment suggest that the transition takes place between a corridor width of 1.2 m and 2.3 m. The total duration of each experimental run is not significantly influenced by the corridor width but by the width of the entrance itself, the number of participants and partly by the motivation. In general, the density in front of the gate as well as the area of high density is increased by widening the corridor and by intensifying the motivation of the participants. However, the results also suggest that also the number of participants significantly influences the occurrence of pushing and the level of density.
在本文中,我们给出了一个入口实验的结果,该实验研究了瓶颈前走廊宽度对密度的影响。这个想法是基于之前的一项研究,该研究表明,入口前的引导系统可以减少等候人员的推挤,从而减少入口的密度。在我们的研究中,我们的目的是找出走廊宽度对拥挤或排队行为的影响程度,以及对密度的影响程度。所提出的实验结果表明,过渡发生在1.2米和2.3米的走廊宽度之间。每次实验的总持续时间不受走廊宽度的显著影响,而是受入口本身的宽度、参与者人数以及部分动机的影响。一般来说,通过拓宽走廊和加强参与者的动机,增加了大门前的密度和高密度区域。然而,研究结果也表明,参与者的数量也会显著影响推搡的发生和密度水平。

We report on two series of experiments, conducted in the frame of two different collaborations designed to study how pedestrians adapt their trajectories and velocities in groups or crowds. Strong emphasis is put on the motivations for the chosen protocols and the experimental implementation. The first series deals with pattern formation, interactions between pedestrians, and decision-making in pedestrian groups at low to medium densities. In particular, we show how pedestrians adapt their headways in single-file motion depending on the (prescribed) leader’s velocity. The second series of experiments focuses on static crowds at higher densities, a situation that can be critical in real life and in which the pedestrians’ choices of motion are strongly constrained sterically. More precisely, we study the crowd’s response to its crossing by a pedestrian or a cylindrical obstacle of 74cm in diameter. In the latter case, for a moderately dense crowd, we observe displacements that quickly decay with the minimal distance to the obstacle, over a lengthscale of the order of the meter.
我们报告了两个系列的实验,在两个不同的合作框架下进行,旨在研究行人如何在群体或人群中适应他们的轨迹和速度。重点强调了所选择的协议和实验实现的动机。第一个系列涉及中低密度下行人群体的模式形成、行人之间的互动以及决策。特别是,我们展示了行人如何根据(规定的)引导者的速度来调整单行运动中的车头时距。第二系列实验的重点是高密度的静态人群,这种情况在现实生活中可能很关键,行人的运动选择受到强烈的空间约束。更准确地说,我们研究了行人或直径74厘米的圆柱形障碍物穿过人群时的反应。在后一种情况下,对于中等密度的人群,我们观察到位移随着距离障碍物的最小距离而迅速衰减,在米量级的长度尺度上。

Comparison of Pedestrian Data of Single File Movement Collected from Controlled Pedestrian Experiment and from Field in Mass Religious Gathering 受控行人实验与群众宗教集会现场行人单文件运动数据的比较

Managing and controlling crowd during mass religious gathering is a challenge for organizers. With good computational capabilities, it is possible to create tools to simulate crowd in real time to aid crowd management. These tools need to be first calibrated and validated with pedestrian empirical data. The empirical data collection from field is difficult and therefore, data collection through controlled pedestrian experiments have become a convenient substitute. However, the ability of experiment data to reproduce actual crowd behavior needs to be examined. This study compared the experiment data with field data collected from mass religious gathering named Kumbh Mela held in India, 2016. The single file movement (pedestrians moving along a single line; SFM) experiment was conducted and its results were compared with the field SFM results. The speed in the field was found to be generally higher than in the experiment for a given density. The results clearly indicate that the pedestrians in the field are motivated to achieve a purpose but participants in the experiments lack the motivation. The pedestrian dynamics of the experiment was found to be different from the field. Hence, the results of pedestrian experiments should not be extrapolated to understand panic, crowd risk situations.
在大规模宗教集会期间管理和控制人群对组织者来说是一项挑战。凭借良好的计算能力,可以创建实时模拟人群的工具来帮助人群管理。这些工具需要首先用行人经验数据进行校准和验证。从现场收集经验数据是困难的,因此,通过受控行人实验收集数据已经成为一种方便的替代品。然而,需要检验实验数据再现实际人群行为的能力。这项研究将实验数据与2016年在印度举行的名为大壶节的大规模宗教集会收集的现场数据进行了比较。进行了单行线运动(行人沿单行线运动;SFM)实验,并将其结果与现场SFM结果进行了比较。对于给定的密度,场中的速度通常高于实验中的速度。研究结果清楚地表明,田野里的行人有动机达到目的,但实验参与者缺乏动机。实验中的行人动力学与现场不同。因此,行人实验的结果不应被推断为了解恐慌、人群风险的情况。

Hence, the results of pedestrian experiments should not be extrapolated to understand panic, crowd risk situations.","PeriodicalId":93276,"journal":{"name":"Collective dynamics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48206084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a novel interactive multi-agent simulation algorithm to model pedestrian movement dynamics. We use statistical techniques to compute the movement patterns and motion dynamics from 2D trajectories extracted from crowd videos. Our formulation extracts the dynamic behavior features of real-world agents and uses them to learn movement characteristics on the fly. The learned behaviors are used to generate plausible trajectories of virtual agents as well as for long-term pedestrian trajectory prediction. Our approach can be integrated with any trajectory extraction method, including manual tracking, sensors, and online tracking methods. We highlight the benefits of our approach on many indoor and outdoor scenarios with noisy, sparsely sampled trajectory in terms of trajectory prediction and data-driven pedestrian simulation.
提出了一种新的交互式多智能体仿真算法来模拟行人运动动力学。我们使用统计技术来计算从人群视频中提取的2D轨迹的运动模式和运动动力学。我们的公式提取了现实世界智能体的动态行为特征,并使用它们来学习动态的运动特征。所学习的行为被用于生成虚拟代理的可信轨迹以及长期行人轨迹预测。我们的方法可以与任何轨迹提取方法集成,包括手动跟踪,传感器和在线跟踪方法。在轨迹预测和数据驱动的行人模拟方面,我们强调了我们的方法在许多具有噪声、稀疏采样轨迹的室内和室外场景中的优势。

Effects of visual information on decision making during way-finding in emergency and non-emergency situations. 紧急和非紧急情况下视觉信息对寻路决策的影响。

Finding the way out of a building during evacuation is not an easy task. Ideally, instructions provide clear and unambiguous information to occupants about the best means to evacuate. However, many times, building occupants may find the best course of action is not always clear. Conflicting or ambiguous cues can make a process that requires a quick response, slow and possibly more dangerous. Emergency signage may be vague, conflicting with other cues, or easily overlooked. The egress route directed by signage may appear difficult to traverse or dangerous. It is crucial then to best understand how evacuees find, interpret, and act upon visual information provided by emergency signage and egress routes in emergency situations. We tested the way visual information of signage and routes is used when an occupant needs to evacuate a building. In a virtual reality experiment, conflicting visual cues were pitted against each other in order to best understand how participants use visual information.

在疏散期间找到建筑物的出口不是一件容易的事。理想情况下,指示向居住者提供关于最佳疏散方式的清晰和明确的信息。然而,很多时候,建筑物的居住者可能会发现最好的行动方案并不总是明确的。相互矛盾或模棱两可的线索会使一个需要快速反应的过程变得缓慢,甚至可能更危险。紧急标志可能是模糊的,与其他线索冲突,或容易被忽视。由标志指示的出口路线可能看起来难以穿越或危险。因此,最好地了解疏散人员如何在紧急情况下发现、解释紧急标志和出口路线提供的视觉信息并采取行动是至关重要的。我们测试了当居住者需要撤离建筑物时,标牌和路线的视觉信息的使用方式。在一个虚拟现实实验中,相互冲突的视觉线索相互对抗,以便最好地了解参与者如何使用视觉信息。
