下一次你乘坐出租车时,先看看它的颜色。一项新研究发现,黄色出租车的追尾几率比蓝色出租车低9%。

科学家连续36个月跟踪了位于新加坡同一车队的4175辆黄色出租车和12525辆蓝色出租车,他们还利用3000多名司机3个月的GPS数据记录,排除了驾驶速度、停车次数和距离远近等混合因素的影响。此外,驾驶黄色和蓝色出租车的司机在年龄、教育水平或驾驶经验等方面也无明显差别。

该团队在3月6日发表于美国《国家科学院院刊》的成果中表示,大量数据(共数百万次观察)使该研究成为将车辆颜色作为影响事故发生率主要因素的首篇研究成果。

可见光条件——日光和夜间街道光也在其中发挥着一定作用。在夜间街灯下,黄色出租车发生追尾的几率比蓝色出租车低19%,而白天黄色出租车的追尾几率则比蓝色低5%。科学家总结称,黄色出租车更加醒目,在低照明度情况下尤其如此,从而给其他司机更长反应时间避免事故。

研究人员表示,将全部车队换成黄色车辆每年将会节省140万美元。他们还计划对比其他颜色车辆的明显性,并调查优步和来福车等打车服务的车辆颜色影响。

Yellow taxis safer than blue ones, study concludes

原文摘要:

The next time you’re about hop into a taxi, you may want to check its color first. A new study finds thatyellow cabs are 9% less likely to be rear-ended than blue ones. For 36 months, scientists tracked 4175 yellow taxis and 12,525 blue taxis from the same Singapore-based fleet; they also used 3 months of data from more than 3000 drivers’ GPS logs to rule out differences in driving speed, number of stops, and distance covered as confounding factors. There were also no significant differences in the age, education level, or experience of drivers assigned to yellow versus blue cabs. The sheer volume of data—totaling millions of observations—makes this the first study able to identify vehicle color as a main contributor to accident rates, the team reports today in the Proceedings of the National Academy of Sciences. Visibility conditions—daylight versus nighttime street lighting—also played a role. Under street lighting, yellow taxis were 19% less likely to be rear-ended than blue, compared with 5% less likely to be rear-ended during the day. The scientists conclude that yellow is more noticeable, especially in low lighting, giving other drivers more reaction time to avoid accidents. Converting the whole fleet to yellow would save about $1.4 million a year, the researchers say. They also plan to compare the visibility of other car colors and investigate the implications of vehicle colors for ride-hailing services like Uber and Lyft.
