大学生经常走路，18-22岁的人在美国任何年龄组中行人受伤的比例最高。这些伤害是由各种个人、人际和环境因素造成的，但有一个因素以前没有仔细考虑过，那就是背着沉重的背包对行人安全的影响。众所周知，背包会减慢步行速度，扰乱人们对环境的感知，因此有理由质疑它们是否也会影响行人的安全行为。96名大学生在虚拟行人环境中参与了20个过马路。一半的穿越是在背着占体重12%的背包的情况下完成的;另一半则是在没有任何负担的情况下完成的。结果表明，参与者走得更慢，在穿过虚拟街道后留下的安全时间更少，并且在背着背包穿越时经历了更频繁的碰撞或与交通的密切联系。他们也错过了更少的安全机会，而携带背包过境。我们对几个人口统计学特征、行人行为和背包使用作为协变量的测试表明，这一发现适用于我们研究中的所有子样本。行人安全和未来的研究的影响进行了讨论。(C)2009爱思唯尔有限公司保留所有权利。
University students walk frequently, and individuals ages 18-22 have among the highest rates of pedestrian injury among any age group in the United States. These injuries are caused by a wide range of individual, interpersonal, and environmental factors, but one factor that has not been previously considered carefully is the influence of wearing a heavy backpack on pedestrian safety. Backpacks are known to slow walking speed and disrupt perception of one's environment, so it is reasonable to question whether they might also influence safe pedestrian behavior. Ninety-six college students engaged in 20 street-crossings within a virtual pedestrian environment. Half the crossings were completed while bearing a backpack weighing 12% of their body weight; the other half were completed without any burdens. Results suggest that participants walked more slowly, left less safe time to spare after crossing the virtual street, and experienced more frequent hits or close calls with traffic when crossing while carrying the backpack. They also missed fewer safe opportunities to cross while carrying the backpack. Our tests of several demographic characteristics, pedestrian behaviors, and backpack use, as covariates suggest the finding holds across all subsamples included in our study. Implications for pedestrian safety and future research are discussed. (C) 2009 Elsevier Ltd. All rights reserved.
