Bicycling is becoming an increasingly utilized mode of transportation in New York City. Technology-related distracted bicycling and helmet use are behaviors that can impact bike safety. The aims of this study were twofold: (1) to determine rates and types of technology-related distracted behaviors among bicyclists in the borough of Manhattan in New York City; and (2) to assess the rate of bicycle helmet use among these cyclists. Bicyclists in five popular riding areas in Manhattan were observed for a total of 50 h using a digital video camera during summer months in 2014. Videos were coded and enumerated for the total number and gender of cyclists, type of bicycle, number wearing headphones/earbuds and/or using a mobile phone, and whether the cyclist was wearing a helmet. Almost 25,000 cyclists were observed across the five selected locations (n = 24,861). Riders were almost four times more likely not to wear a helmet on rental bikes as compared with non-rentals (Citi Bike(®) OR 3.8; 95% CI 2.5, 5.9: other rental OR 3.8; 95% CI 3.0, 4.9). Significantly increased odds of not wearing a helmet were observed for females relative to males (OR 1.4; 95% CI 1.1, 1.8) across varied times and locations. Overall, rates of technology-related distraction were low, with headphone use being most prevalent. Males were more likely to wear headphones/earbuds (OR 2.0; 95% CI 1.4, 2.9), as were cyclists on Citi Bikes relative to other rental bikes (OR 2.2; 95% CI 1.3, 3.6). Findings from this study contribute to the growing literature on distracted biking and helmet use among bike share program riders and other cyclists and can inform policymakers and program planners aiming to improve bicycle safety in urban settings.
在纽约市，骑自行车正日益成为一种被广泛使用的交通方式。与技术相关的分心骑行行为和头盔使用情况是会影响自行车安全的行为。本研究的目的有两个：（1）确定纽约市曼哈顿区骑自行车者中与技术相关的分心行为的发生率和类型；（2）评估这些骑自行车者中使用自行车头盔的比例。2014年夏季，使用数码摄像机在曼哈顿五个热门骑行区域对骑自行车者进行了总计50小时的观察。对视频进行编码并统计骑自行车者的总数、性别、自行车类型、戴耳机/耳塞和/或使用手机的人数，以及骑车人是否佩戴头盔。在五个选定地点共观察到近25,000名骑自行车者（n = 24,861）。与非租赁自行车相比，租赁自行车的骑行者不戴头盔的可能性几乎是非租赁自行车骑行者的四倍（花旗自行车（®）比值比3.8；95%置信区间2.5，5.9：其他租赁自行车比值比3.8；95%置信区间3.0，4.9）。在不同时间和地点，女性不戴头盔的几率相对于男性显著增加（比值比1.4；95%置信区间1.1，1.8）。总体而言，与技术相关的分心率较低，使用耳机最为普遍。男性更有可能戴耳机/耳塞（比值比2.0；95%置信区间1.4，2.9），花旗自行车的骑行者相对于其他租赁自行车的骑行者也是如此（比值比2.2；95%置信区间1.3，3.6）。本研究的结果有助于丰富关于共享单车项目骑行者和其他骑自行车者分心骑行和头盔使用情况的文献，并可为旨在改善城市环境中自行车安全的政策制定者和项目规划者提供参考。
