A recent study from the University of California, Berkeley in association with National Singapore University and the Chinese University of Hong Kong came to a conclusion that taxis with yellow color are safer than blue colored taxis.
Why color of the taxi?
This should be your first thought when you catch a taxi next time. A study from the University of California, Berkeley in association with National Singapore University and Chinese University of Hong Kong published in PNAS journal found that the yellow ones are less likely to be rear-ended when compared to the blue taxis by a factor of 9%. Though the percentage statistics might be only 9%, in a million number of taxis that would make around 90,000 and definitely you don’t want to put yourself at risk taking a ride in one.
The study ain’t an obsolete thought or extrapolation, rather a volunteer intense process in cooperation with over 16,000 taxis from Singapore. The study took 3 years and employed 4,175 yellow taxis and 12,525 blue taxis, where scientists tracked their transit to gather data. In order to bring a normalization they also collected 3 months of data from over 3000 cab drivers with GPS, consisting of driving speed, number stops, distance covered, hours of continuous drive etc.
Accounting numerous factors
Before making a final conclusion the scientists examined from head to toe, in order to include or exclude factors that would influence the results. There were no significant aspects regarding drivers experience, education or age that would influence the final data. However, the visibility was one factor that played a crucial role here. In the night street light, yellow taxis scored better than blue ones. The data suggests that yellow taxis are 19% less likely to be rear-ended during nighttime under street light compared to blue one, to over a 5% less chance in the day time.
The final numbers concluded that yellow is a safer choice in the low light due to its better visibility. This factor will allow a safe reaction time for the other driver to avert the accident. That’s not all of it, if the all the taxis were to be converted into yellow, it would save around $1.4 million a year by avoiding accidents. In their further studies, they are planning to compare the other colors to bring a standard choice for taxi services like Uber and Lyft. Also, this study might contribute a color pallet for cars which would help tone the car color to make is visually prominent in low lights.
