一项发表在《柳叶刀·公共卫生》上的研究表明，全球道路伤害和死亡率在1990年至2023年间下降了超过30% [1]。然而，这一进展在各地发展水平的差异中并未均匀分布。
低收入国家承担了全球90%的道路死亡人数，且缺乏相应的安全措施 [1]。根据世卫组织数据，2011年至2025年间道路交通死亡人数虽下降了21%，但2025年仍有超过110万人死于车祸 [1]。道路交通伤害已成为5至29岁人群的首要死因 [1]。
作为发达国家的代表，美国的情况也存在波动。该国道路死亡人数在2021年达到43,000人的峰值后开始下降，2024年和2025年数据继续改善 [1]。具体而言，2025年美国司机撞死行人的比例比前一年减少了7% [1]。尽管如此，美国仍需应对驾驶分心等持续挑战 [1]。
A study published in The Lancet Public Health found that global road injury and mortality rates have fallen by more than 30 percent between 1990 and 2023. [1] However, this progress has not extended uniformly across all regions, with low-income countries failing to achieve significant improvements. [1]
Despite the overall decline, road traffic remains a major public health threat worldwide. According to World Health Organization data, more than 1.1 million people died in road crashes in 2025, making traffic accidents the leading cause of death for people aged 5 to 29. [1] Low-income countries bear a disproportionate burden, accounting for 90 percent of road deaths while lacking adequate safety measures. [1]
The global picture masks significant regional variation. Between 2011 and 2025, road traffic deaths declined by 21 percent, yet the absolute toll remains substantial. [1] The United States has experienced recent improvements after a troubled period: road deaths peaked at 43,000 in 2021 before beginning to decline, with 2024 and 2025 data continuing to show improvement. [1] In 2025, the proportion of pedestrians killed by American drivers decreased by 7 percent compared to the previous year. [1] Nevertheless, the country continues to grapple with challenges including distracted driving. [1]
