Regular cycling has been shown to improve health and has a role in tackling the threats posed by obesity and inactivity. Cycle collisions, particularly those involving motorised vehicles, can lead to significant mortality and morbidity and are currently a barrier to wider uptake of cycling. There is evidence that the conspicuity of cyclists is a factor in many injury collisions. Low-cost, easy to use retro-reflective and fluorescent clothing and accessories ('conspicuity aids') are available. Their effectiveness in reducing cycling collisions is unknown. The study is designed to investigate the relationship between the use of conspicuity aids and risk of collision or evasion crashes for utility and commuter cyclists in the UK.
METHODS/DESIGN: A matched case-control study is proposed. Cases are adult commuter and utility cyclists involved in a crash resulting from a collision or attempted evasion of a collision with another road user recruited at a UK emergency department. Controls are commuter and utility cyclists matched by journey purpose, time and day of travel and geographical area recruited at public and private cycle parking sites. Data on the use of conspicuity aids, crash circumstances, demographics, cycling experience, safety equipment use, journey characteristics and route will be collected using self-completed questionnaires and maps. Conditional logistic regression will be used to calculate adjusted odds ratios and 95% confidence intervals of the risk of a crash when using any item of fluorescent or reflective clothing or equipment.
This study will provide information on the effectiveness of conspicuity aids in reducing the risk of injury to cyclists resulting from crashes involving other road users.
定期骑自行车已被证明有益于健康，并且在应对肥胖和缺乏运动带来的威胁方面发挥着作用。自行车碰撞，特别是涉及机动车辆的碰撞，可能导致严重的死亡率和发病率，并且目前是广泛采用自行车的障碍。有证据表明，自行车的可见性是许多伤害碰撞的一个因素。现已有低成本、易于使用的反光和荧光服装和配件（“可见性辅助设备”）。它们在减少自行车碰撞方面的效果尚不清楚。本研究旨在调查英国实用自行车和通勤自行车使用者使用可见性辅助设备与碰撞或回避碰撞的风险之间的关系。
方法/设计：拟议采用匹配病例对照研究。病例是在英国急诊部门招募的因与其他道路使用者碰撞或试图回避碰撞而导致事故的成年通勤和实用自行车骑手。对照是根据行程目的、时间和旅行日期以及地理位置，在公共和私人自行车停车点招募的通勤和实用自行车骑手。使用自我完成的问卷和地图收集关于可见性辅助设备使用情况、碰撞情况、人口统计学、骑行经验、安全设备使用情况、行程特征和路线的数据。将使用条件逻辑回归计算使用任何荧光或反光服装或设备时发生碰撞的风险的调整优势比和 95%置信区间。
本研究将提供有关可见性辅助设备在降低涉及其他道路使用者的碰撞导致的自行车骑手受伤风险方面的有效性的信息。
