UPS has figured out a way to reduce millions of gallons of fuel each year. That adds up to a savings of about $300 to $400 million dollars. Better yet, they will reduce emissions from their carriers that's equivalent to 22,000 passenger cars!
It's part of figuring out of a very complicated routing problem that has been growing. People are buying more products online and the rate is growing every year. Retailers and the shipping companies that work with them need ways to get the deliveries to their customers as fast as possible.
The level of complexity UPS has to deal with in its shipping is immense. The number of possible routes one driver delivering just 25 packages can choose is 15 trillion trillion. It is a version of the traveling salesman problem turned into a nightmare.
The no-left-turn policy was given to UPS drivers almost 15 years ago. According to information from a UPS press release, it was a made after looking at the general flow of regular traffic. The only issue was that it was basically a guess — they needed solid proof it worked.
UPS trucks do not look any different than they did in the '90s, but what's inside has changed considerably. They now have sensors that check up on the driver's daily routine like when the truck is about to break. It even reads when the truck door opens and closes.
ORION calculated a no-left-turn policy from two additional factors. The first is the increased safety it brings to drivers — left turns, in general, tend to be more dangerous when crossing an intersection. The second is better handling with stoplights.
10. What Can Be Gained From This Style Of Driving?
Multiple tests showed that despite making more turns, the strategy somehow uses less fuel. It would make sense for everyone to adopt this habit, but it only works if everyone drives in this style. If just a few drivers refuse to cooperate than the efficiency system won't work.
No driver is making one complete route with no left turn, but the way the system is designed it will take as many rights as possible. It may seem strange, but the amount of savings and safety UPS gains from this decision makes it worth a shot. One of the directors at UPS even admits to using it when driving his own car.
