冬奥会观赛人群出行调查、行人拥挤踩踏、行人避让数据

基于冬奥会的赛事特性，针对不同个体的出行需求，设计调查问卷。采用SP调查与RP调查相结合的方法，获得观赛人群的出行行为数据，包括出行时间、出行目的、出行方式选择等。基于实测数据，探究单因素及组合因素交互作用对出行行为的影响，获取冬奥人群出行的基本特征。
本数据集基于计算模拟的方法获得。为了探究行人在瓶颈处的拥挤踩踏情况，对行人在步行设施、瓶颈处的拥挤和踩踏行为进行仿真模拟再现了行人疏散过程中的移动阻滞、相互挤压，以及连续踩踏等现象，获取并记录了在疏散过程中瓶颈前疏散人数、踩踏情况、行人时空分布等方面数据。
本数据集通过组织可控实验的方法获取。为了探究障碍物对行人避让行为的影响机制，在固定通道内组织行人群体避让障碍物的实验并使用摄像机对现场进行摄像，后期使用成象物体跟踪软件petrack对视频进行追踪，获取并记录了行人避让与超越行为特征、空间障碍物规模形状的变化对行人流疏散效率、移动瓶颈通过能力和行人群体宏观现象的影响。

Based on the event characteristics of the Winter Olympics and tailored to the travel needs of different individuals, a questionnaire survey was designed. The combined Stated Preference (SP) and Revealed Preference (RP) survey methods were adopted to collect travel behavior data of spectators, including travel time, travel purpose, travel mode choice, etc. Based on the measured data, the impacts of single factors and the interaction of combined factors on travel behavior were explored, and the basic travel characteristics of the Winter Olympics-related crowd were obtained.

This dataset was obtained through computational simulation. To explore the congestion and stampede of pedestrians at bottlenecks, simulation experiments were conducted on the congestion and stampede behaviors of pedestrians in pedestrian facilities and at bottlenecks, which reproduced phenomena such as movement stagnation, mutual extrusion, and continuous stamping during pedestrian evacuation. Data including the number of evacuees in front of the bottleneck, stampede situation, and spatiotemporal distribution of pedestrians during the evacuation process were collected and recorded.

This dataset was obtained through controlled experiments. To explore the influence mechanism of obstacles on pedestrian evasive behaviors, experiments on pedestrian groups avoiding obstacles were conducted in fixed corridors, and the scene was filmed with cameras. Later, the video was tracked using the image object tracking software petrack. The characteristics of pedestrian evasion and overtaking behaviors, as well as the impacts of changes in the scale and shape of spatial obstacles on the evacuation efficiency of pedestrian flow, the passing capacity of moving bottlenecks, and the macroscopic phenomena of pedestrian groups, were collected and recorded.
