Boys experience more injuries as pedestrians than girls. The aim of this study was to compare how boys and girls cross streets in order to identify factors that differentially influence their injury risk as pedestrians.
Using a fully immersive virtual reality (VR) system interfaced with a 3D movement measurement system, various measures of children's street-crossing behaviors were taken.
At the start of the crossing, boys selected smaller (riskier) inter-vehicle gaps to cross into than girls. Subsequently, as they crossed, they showed greater attention to traffic, shorter start delay, and more evasive action than girls, which are strategies that could reduce risk as a pedestrian. Despite these efforts, however, boys experienced more hits and close calls than girls.
To enhance their safety as pedestrians, girls adopt a proactive approach and select larger inter-vehicle gaps to cross into, whereas boys apply a reactive approach aimed at managing the risk created by having selected smaller (riskier) gaps. Girls' proactive approach yielded safer outcomes than boys' reactive strategy.
男孩在行人中比女孩更容易受伤。本研究旨在比较男孩和女孩过马路的方式，以确定影响他们作为行人受伤风险的不同因素。
使用与 3D 运动测量系统接口的全沉浸式虚拟现实 (VR) 系统，对儿童过马路行为的各种措施进行了测量。
在开始过马路时，男孩选择的车辆间隙比女孩小（风险更大）。随后，在过马路的过程中，他们比女孩更关注交通，启动延迟更短，回避动作更多，这些策略可以降低行人的风险。然而，尽管如此，男孩还是比女孩经历了更多的撞击和险些被撞。
为了提高他们作为行人的安全性，女孩采取了积极主动的方法，选择更大的车辆间隙过马路，而男孩则采取了反应式的方法，旨在管理选择更小（风险更大）间隙所带来的风险。女孩的主动方法比男孩的被动策略产生了更安全的结果。
