School-based cycling education programs aim to improve cycling safety and participation amongst children. Available research suggests that typical programs, which focus on bicycle manoeuvring skills, have limited effects on behaviour observed on a track or planned route. The current study uses theoretically more valid, naturalistic cycling data, to evaluate Safe Cycle, a program that incorporates hazard and self-awareness training. Soon after Safe Cycle was delivered at treatment schools, research bicycles instrumented with a rearward- and a forward-facing camera were loaned to six children from treatment schools and six children from (waitlist) control schools. In each group half the children were in Year 6, and half were in Year 7/8. Each child was instructed to ride the research bicycle instead of their own bicycle for the 1-2 weeks that they had a research bicycle. Video data were reduced using a purpose-designed coding scheme that identified whether participants performed specific safety-relevant behaviours in appropriate circumstances. While the participants controlled their bicycles well, gave way appropriately to traffic at intersections, and stopped at red lights, participants frequently removed one or both hands from the handlebars, and seldom signalled turns, conducted over-shoulder-checks when changing lanes, or looked in multiple directions at intersections (except when crossing a road). While aspects of design and small sample sizes limited evaluation findings, this research demonstrated the feasibility and potential of naturalistic data to support cycling education program evaluation. Further, the study substantially extended available naturalistic study of children's cycling behaviour to highlight behaviours which might be targeted by cycling safety initiatives.
以学校为基础的自行车教育项目旨在提高儿童的自行车骑行安全性和参与度。现有研究表明,专注于自行车操控技能的典型项目对在赛道或规划路线上观察到的行为影响有限。本研究使用理论上更有效的自然主义自行车骑行数据,来评估“安全骑行”项目,该项目纳入了危险意识和自我意识培训。在治疗学校实施“安全骑行”项目后不久,配备了前后摄像头的研究用自行车被借给了来自治疗学校的6名儿童和来自(候补名单)对照学校的6名儿童。每组中,一半儿童是六年级,一半是七年级/八年级。每个孩子在拥有研究用自行车的1至2周内,被要求骑研究用自行车而不是自己的自行车。视频数据使用专门设计的编码方案进行简化,该方案确定参与者是否在适当情况下表现出特定的安全相关行为。虽然参与者自行车操控良好,在十字路口能适当给车辆让路,并在红灯前停车,但他们经常将一只或两只手从车把上移开,很少打转向灯、变道时进行回头检查,或在十字路口观察多个方向(过马路时除外)。虽然设计方面的问题和小样本量限制了评估结果,但这项研究证明了自然主义数据支持自行车教育项目评估的可行性和潜力。此外,该研究极大地扩展了现有的关于儿童自行车骑行行为的自然主义研究,以突出自行车安全倡议可能针对的行为。
