介绍： This is Scientific American's 60-second Science, I'm Steve Mirsky.
With a full month of the regular season to play, the 2019 New York Yankees had set a Major League Baseball record for injuries. That medical crisis led to what the online sports publication The Athletic reported on January 3rd as "sweeping changes" to their training and strength-and-conditioning programs. When I read that news, I thought, of course, of traffic cameras, which sometimes, and reasonably, get placed at sites that have a disproportionate number of accidents in a given year.
"The fact that there's a higher rate of accidents will be partly due to chance because it will fluctuate over the course of time. Sometimes it will be less; sometimes it will be high."

常规赛赛程还有一个月，而2019年纽约洋基队已经创下了职业棒球大联盟的伤病纪录。这场医疗危机导致在线体育刊物《The Athletic》在1月3日进行了报道，称洋基队的训练和力量与调节项目发生了“彻底改变”。我看到这则新闻时，自然想到了交通摄像头，它有时被合理地安装在一年中事故数量不成比例的地点。
“事故发生率较高的部分原因是偶然性，因为事故会随着时间的推移而波动。有时会少一些，有时会很高。”
