The COVID-19 pandemic has significantly reduced human activities through city lock-downs and restricted traffic flows. It had been suggested that roadkill occurrences are strongly associated with traffic volume. I evaluated the association between traffic volume and roadkill during COVID-19, from March to May 2020, using 26,130 roadkill data points recorded from the highway network in Hokkaido from 2010 to 2020, Japan. Results showed that there was a significant positive correlation between roadkill numbers and traffic volume over the past decade. However, the roadkill during COVID-19 restricted human activity did not diminish, although traffic volume decreased during this period.

COVID-19 大流行通过城市封锁和交通流量限制显着减少了人类活动。有人提出，道路交通事故的发生与交通量密切相关。我使用 2010 年至 2020 年日本北海道高速公路网络记录的 26,130 个道路交通事故数据点，评估了 COVID-19 期间（2020 年 3 月至 5 月）的交通量与道路交通事故之间的关联。结果表明，在过去十年中，道路死亡人数与交通量之间存在显着的正相关关系。然而，尽管在此期间交通量有所下降，但 COVID-19 期间人类活动受限的道路交通事故并未减少。
