Abstract

The number of bicycle crashes is increasing in many European countries. In the Netherlands, a country well-known for its high-quality cycling infrastructure and cycling culture, bicycle crashes are also increasing, especially for e-bike users. Smart bicycle technologies, such as safety warning support systems, could contribute to reducing crash risk for cyclists. However, perceived safety and trust in these technologies are determinant factors in accepting and using such technologies. This study investigated users’ perceived safety, perceived trust, and perceived performance with a context-aware prototype warning system to support cyclists in the real world. In addition, it investigated users’ riding behaviour changes when receiving warnings in high crash risk locations by collecting GPS data. The above were evaluated through a field trial experiment using three rides per participant, with the first one serving as a control ride and a follow-up questionnaire after each ride conducted in Enschede, the Netherlands, between April and May 2024, with a sample of 46 participants. Results show that participants’ perceived safety increased after they tried out the prototype warning system. In addition, it was found that warning systems positively influence participants’ riding behaviour, since they reduced their speed. This study proves the potential benefits of smart bicycle technologies in improving cyclists’ safety.
在许多欧洲国家,自行车事故的数量正在增加。在荷兰,一个以其高质量的自行车基础设施和自行车文化而闻名的国家,自行车事故也在增加,特别是对于电动自行车用户。智能自行车技术,如安全预警支持系统,可能有助于降低骑车者的撞车风险。然而,对这些技术的感知安全和信任是接受和使用这些技术的决定因素。本研究通过情境感知原型预警系统调查了现实世界中骑车者的感知安全、感知信任和感知表现。此外,它还通过收集GPS数据,调查用户在高碰撞风险位置收到警告时的骑行行为变化。以上是通过现场试验来评估的,每位参与者使用三次骑行,第一次作为对照骑行,每次骑行后进行后续问卷调查,于2024年4月至5月在荷兰恩斯赫德进行,样本为46名参与者。实验结果表明,实验对象在试用了原型预警系统后,安全感有所提高。此外,研究发现,警告系统对参与者的骑行行为有积极影响,因为它们降低了他们的速度。这项研究证明了智能自行车技术在提高骑自行车者安全方面的潜在效益。
