Power-Two-Wheelers (PTWs) constitute a vulnerable class of road users with increased frequency and severity of accidents. The present paper focuses of the PTW accident risk factors and reviews existing literature with regard to the PTW drivers' interactions with the automobile drivers, as well as interactions with infrastructure elements and weather conditions. Several critical risk factors are revealed with different levels of influence to PTW accident likelihood and severity. A broad classification based on the magnitude and the need for further research for each risk factor is proposed. The paper concludes by discussing the importance of dealing with accident configurations, the data quality and availability, methods implemented to model risk and exposure and risk identification which are critical for a thorough understanding of the determinants of PTW safety.
助力车（PTWs）构成了道路使用者中一个脆弱的群体，其事故发生的频率和严重程度都有所增加。本文主要关注助力车事故的风险因素，并对现有文献进行回顾，探讨了助力车驾驶员与汽车驾驶员的相互作用，以及与基础设施元素和天气条件的相互作用。揭示了几个关键的风险因素，这些因素对助力车事故发生的可能性和严重程度有不同程度的影响。根据每个风险因素的重要性和进一步研究的需求，提出了一种广泛的分类方法。本文最后讨论了处理事故配置、数据质量和可用性、用于建模风险和暴露的方法以及风险识别的重要性，这些对于深入了解助力车安全的决定因素至关重要。
