The aim of this study was to estimate use of helmets, lights, and visible clothing among cyclists and to examine trip and personal characteristics associated with their use.
Using data from a study of transportation infrastructure and injuries to 690 adult cyclists in Toronto and Vancouver, Canada, we examined the proportion who used bike lights, conspicuous clothing on the torso, and helmets on their injury trip. Multiple logistic regression was used to examine associations between personal and trip characteristics and each type of safety equipment.
Bike lights were the least frequently used (20% of all trips) although they were used on 77% of trips at night. Conspicuous clothing (white, yellow, orange, red) was worn on 33% of trips. Helmets were used on 69% of trips, 76% in Vancouver where adult helmet use is required by law and 59% in Toronto where it is not. Factors positively associated with bike light use included night, dawn and dusk trips, poor weather conditions, weekday trips, male sex, and helmet use. Factors positively associated with conspicuous clothing use included good weather conditions, older age, and more frequent cycling. Factors positively associated with helmet use included bike light use, longer trip distances, hybrid bike type, not using alcohol in the 6 hours prior to the trip, female sex, older age, higher income, and higher education.
In two of Canada's largest cities, helmets were the most widely used safety equipment. Measures to increase use of visibility aids on both daytime and night-time cycling trips may help prevent crashes.
本研究旨在估计自行车手头盔、车灯和可视服装的使用情况，并探讨与其使用相关的出行和个人特征。
本研究利用加拿大多伦多和温哥华一项关于交通基础设施和伤害的研究数据，调查了 690 名成年自行车手在受伤出行时使用自行车车灯、躯干显眼服装和头盔的比例。采用多变量逻辑回归分析方法，考察了个人和出行特征与每种安全设备使用之间的关联。
自行车车灯的使用率最低（所有出行的 20%），尽管它们在夜间出行中使用率为 77%。显眼服装（白色、黄色、橙色、红色）的使用率为 33%。头盔的使用率为 69%，在要求成年人戴头盔的温哥华使用率为 76%，而在不做要求的多伦多使用率为 59%。与使用自行车车灯相关的因素包括夜间、黎明和黄昏出行、恶劣天气条件、工作日出行、男性、以及头盔使用。与使用显眼服装相关的因素包括良好的天气条件、年龄较大、以及更频繁的骑行。与使用头盔相关的因素包括使用自行车车灯、更长的出行距离、混合自行车类型、在出行前 6 小时内未饮酒、女性、年龄较大、较高的收入和较高的教育程度。
在加拿大的两个最大城市中，头盔是最广泛使用的安全设备。增加日间和夜间骑行出行时可视辅助工具使用的措施，可能有助于防止事故发生。
