This study aimed to explore the trend and main influencing factors of road traffic accidents in Guangzhou, China, from 2007 to 2020 and to provide a reference and guidance for government decision-making.
A retrospective cohort study was used to describe road traffic accidents in Guangzhou. According to the population types, all people with road traffic accidents were divided into migrant workers and the control population. We divided road users, administrative districts, motorcycle types and injury levels into subgroups to investigate the characteristics of road traffic accidents in Guangzhou. The road traffic accident data were derived from the Guangzhou Public Security Traffic Management Integrated System.
The incidence rate of road traffic accidents per 10,000 vehicles in Guangzhou decreased from 36.55 in 2007 to 10.07 in 2012, remained relatively stable at 9.47 in 2017, and finally rose to 11.12 in 2020. The injury rate showed the same trend as the incidence rate, while the mortality rate gradually decreased from 14.21 in 2007 to 5.19 in 2020. Vulnerable road users such as motorized two-to-three-wheeler drivers and migrant workers were casualties in more than 80% of the cases. The proportion of casualties involving mopeds and electric bicycles increased rapidly after 2018. Motor vehicle drivers frequently caused road traffic accidents and were most often uninjured.
Road safety in Guangzhou has shown a clear trend of improvement, but casualties are uneven across administrative districts. More attention should be given to motorized two-to-three-wheelers, migrant workers, and road traffic violations by uninjured individuals.
本研究旨在探讨2007年至2020年中国广州道路交通事故的趋势及主要影响因素，为政府决策提供参考和指导。
采用回顾性队列研究描述广州道路交通事故情况。根据人群类型，将所有道路交通事故人群分为农民工和对照人群。将道路使用者、行政区、摩托车类型和伤害程度分为亚组，调查广州道路交通事故特征。道路交通事故数据来源于广州公安交通管理综合系统。
广州每万辆车的道路交通事故发生率从2007年的36.55降至2012年的10.07，2017年相对稳定在9.47，最终在2020年升至11.12。伤害率与发生率趋势相同，而死亡率从2007年的14.21逐渐降至2020年的5.19。超过80%的案例中，机动两三轮摩托车驾驶员和农民工等弱势道路使用者为伤亡人员。2018年后，涉及轻便摩托车和电动自行车的伤亡比例迅速上升。机动车驾驶员频繁引发道路交通事故，且大多未受伤。
广州道路安全呈现明显改善趋势，但各行政区伤亡情况不均衡。应更加关注机动两三轮车、农民工以及未受伤人员的道路交通安全违法行为。
