Abstract

BACKGROUND

Pedestrians distracted by digital devices or other activities are at a higher risk of injury as they cross streets. We sought to describe the incidence of pedestrians distracted by digital devices or other activities at two highly traveled urban intersections after the implementation of a pedestrian safety intervention at one of the intersections.

METHODS

This was an observational field study of two urban intersections. Two investigators were stationed at each of the four corners of the intersection. Each pair of observers included one "person counter" and one "behavior counter". The "person counter" tallied every individual who approached that corner from any of the three opposing corners. The "behavior counter" tallied every individual approaching from the three opposing corners who were exhibiting any of the following behaviors: 1) eating, 2) drinking, 3) wearing ear buds/headphones, 4) texting, 5) looking at mobile phone or reading something on mobile phone, or 6) talking on mobile phone. Every 15 min, each pair of observers rotated to the next corner of the same intersection, allowing each pair of observers to complete one 15-min observation at each of the four corners of the intersection. Intersection A had stencils at the curb cuts of each corner alerting pedestrians to put down a digital device while crossing the intersection while intersection B did not.

RESULTS

1362 pedestrians were observed; of those, 19 % were distracted by another activity at both intersections. Of the total, 9 % were using ear buds/headphones; 8 % were using a digital device (talking, texting, or looking down at it); and 2 % were eating or drinking. Inter-observer validity among observers (kappa) was 98 %. Of those that were distracted, 5 % were either using an assistive device (cane, walker, motorized scooter) or walking with a child (either on foot or in stroller). There were no differences in the proportion of pedestrians who were distracted at either intersection, except that more pedestrians were talking on a cell phone while crossing intersection B.

CONCLUSIONS

It is unclear to what degree a pedestrian safety messaging campaign is effective in decreasing distraction by digital devices. Further evaluation of the effect of posted warnings about pedestrian distraction on the safety of crossing behaviors is needed.

摘要

背景

在过马路时,被数字设备或其他活动分散注意力的行人受伤风险更高。我们试图描述在其中一个十字路口实施行人安全干预措施后,在两个交通繁忙的城市十字路口被数字设备或其他活动分散注意力的行人的发生率。

方法

这是一项对两个城市十字路口进行的观察性实地研究。两名调查人员分别驻守在十字路口的四个角落。每对观察员包括一名“人数统计员”和一名“行为统计员”。“人数统计员”统计从三个相对角落中的任何一个接近该角落的每一个人。“行为统计员”统计从三个相对角落接近且表现出以下任何一种行为的每一个人:1)吃东西,2)喝东西,3)戴着耳塞/耳机,4)发短信,5)看手机或在手机上阅读东西,或6)打电话。每15分钟,每对观察员轮换到同一十字路口的下一个角落,使每对观察员能够在十字路口的四个角落各完成一次15分钟的观察。十字路口A在每个角落的路边切口处有模板,提醒行人在过马路时放下数字设备,而十字路口B没有。

结果

观察到1362名行人;其中,19%的行人在两个十字路口都被其他活动分散了注意力。在总数中,9%的人使用耳塞/耳机;8%的人使用数字设备(打电话、发短信或低头看);2%的人在吃东西或喝东西。观察员之间的观察者间效度(kappa值)为98%。在那些注意力分散的人中,5%的人要么使用辅助设备(手杖、助行器、电动滑板车),要么带着孩子行走(步行或坐在婴儿车里)。在两个十字路口,注意力分散的行人比例没有差异,只是在穿过十字路口B时,更多的行人在打电话。

结论

行人安全宣传活动在多大程度上有效减少数字设备造成的注意力分散尚不清楚。需要进一步评估张贴的关于行人注意力分散的警告对过马路行为安全性的影响。
