While cycling is promoted as a clean, energy-efficient mode of transport generating physical activity, the number of injured cyclists must decrease to achieve traffic safety goals. The extent of the single bicycle crashes (SBCs) and crash causes are rather well studied. This study expands this knowledge by focusing on differences in injury severity. The aim of the study is to investigate the relationship between injury severity and characteristics of the crash and the cyclist with focus on SBCs. Furthermore, injury risk is calculated for different age classes and sexes, as well as for different purposes of the trip. The results are based on injured cyclists in Sweden (N = 105,836) registered in STRADA, 2010-2019, by both the police and accident and emergency departments (A&Es), with a special focus on injury severity reported by the A&Es. Binary logistic regression was applied to analyse how the odds of being severely injured differed for different cyclists and situations. Results from of the National Travel Survey, 2011-2016, were used to study differences in distance travelled with respect to sex, age group and purpose of the trip. Given that the cyclist is injured in an SBC, the results show a higher probability of being severely injured (maximal AIS 3 or more) for cyclists 45 years or older compared to younger cyclists, for males compared to females and for cyclists not wearing a helmet compared to cyclists wearing a helmet. A higher probability for severe injury was also found for crashes occurring during leisure trips compared to work/school trips, crashes occurring during weekdays compared to weekends and crashes at intersections and road stretches compared to pedestrian and cycle paths. Furthermore, the risk of being severely injured in an SBC per km travelled was higher for cyclists aged 45 and older and during a leisure trip.
虽然骑自行车被宣传为一种清洁、节能的交通方式，可以带来身体活动，但必须减少受伤自行车骑手的数量，才能实现交通安全目标。单次自行车碰撞（SBC）的程度及其原因已经得到了相当充分的研究。本研究通过关注伤害严重程度的差异，扩展了这方面的知识。本研究的目的是调查伤害严重程度与碰撞和骑手特征之间的关系，重点关注 SBC。此外，还计算了不同年龄组和性别以及不同出行目的的受伤风险。研究结果基于瑞典 STRADA 登记的 2010-2019 年期间，警察和事故与急诊部门（A&Es）登记的受伤自行车骑手（N=105836），特别关注 A&Es 报告的伤害严重程度。采用二元逻辑回归分析不同骑手和情况下严重受伤的可能性差异。使用 2011-2016 年国家旅行调查的结果，研究了不同性别、年龄组和出行目的的行驶距离差异。鉴于骑手在 SBC 中受伤，结果表明，与年轻骑手相比，45 岁或以上的骑手、男性骑手以及未戴头盔的骑手严重受伤的可能性更高（最大 AIS 3 或更高）。与工作/上学出行相比，休闲出行中发生的碰撞、工作日发生的碰撞、交叉口和道路段发生的碰撞比行人和自行车道发生的碰撞更有可能导致严重受伤。此外，45 岁及以上骑手和休闲出行期间每骑行一公里严重受伤的风险更高。
