在所有年龄组中，大学年龄段的行人受伤发生率最高。可能导致该年龄组行人受伤率升高的一个因素是在过马路时被移动的设备分散注意力而受伤。检查年轻的成年人行人安全是否受到损害，而通过一个虚拟的步行街，而分心使用互联网上的移动的“智能手机”。一个内的主题设计与92名年轻人实施。参与者穿过一条虚拟的步行街20次，一半时间是在不分心的情况下，另一半时间是在完成一个由电子邮件驱动的“寻宝游戏”时，通过手机上的移动的互联网回答一些普通的问题。行人行为的六项措施进行了评估，在交叉路口。参与者还报告了过马路和使用移动的互联网的典型模式。参与者报告说，他们在日常生活中经常使用移动的互联网，包括在穿过街道时。在虚拟的街道环境中，当参与者被互联网使用分散注意力时，行人的行为发生了很大的变化，通常更危险。当分心时，参与者等待更长时间才过马路（F = 42.37），错过了更多的安全穿越机会（F = 42.63），当有安全间隙时，开始穿越所需的时间更长（F = 53.03），向左和向右看的次数较少（F = 124.68），花更多的时间从道路上看（F = 1959.78），更有可能被迎面而来的车辆撞到或差点被撞到（F = 29.54;所有ps< 0.01）。在控制了随机顺序、参与者性别、年龄和种族以及行人习惯和移动的互联网体验后，结果得以保留。当参与者同时使用移动的互联网和过马路时，行人的行为受到影响，并且通常比没有分心的过马路时危险得多。这一发现加强了对行人分心行为风险的认识。
College-age individuals have the highest incidence of pedestrian injuries of any age cohort. One factor that might contribute to elevated pedestrian injuries among this age group is injuries incurred while crossing streets distracted by mobile devices. Examine whether young adult pedestrian safety is compromised while crossing a virtual pedestrian street while distracted using the internet on a mobile “smartphone.” A within-subjects design was implemented with 92 young adults. Participants crossed a virtual pedestrian street 20 times, half the time while undistracted and half while completing an email-driven “scavenger hunt” to answer mundane questions using mobile internet on their cell phones. Six measures of pedestrian behavior were assessed during crossings. Participants also reported typical patterns of street crossing and mobile internet use. Participants reported using mobile internet with great frequency in daily life, including while walking across streets. In the virtual street environment, pedestrian behavior was greatly altered and generally more risky when participants were distracted by internet use. While distracted, participants waited longer to cross the street (F = 42.37), missed more safe opportunities to cross (F = 42.63), took longer to initiate crossing when a safe gap was available (F = 53.03), looked left and right less often (F = 124.68), spent more time looking away from the road (F = 1959.78), and were more likely to be hit or almost hit by an oncoming vehicle (F = 29.54; all ps< 0.01). Results were retained after controlling for randomized order; participant gender, age, and ethnicity; and both pedestrian habits and mobile internet experience. Pedestrian behavior was influenced, and generally considerably riskier, when participants were simultaneously using mobile internet and crossing the street than when crossing the street with no distraction. This finding reinforces the need for increased awareness concerning the risks of distracted pedestrian behavior.
