Yesterday I was watching “The Mythbusters”, and they showed a demonstration of what, for me, is one of the most astonishing logistics optimization rule created so far. UPS, a logistics delivery company, came out with a really smart solution when designing the optimal routes their trucks had to make when delivering packages. UPS engineers found that left-hand turns were a major drag on efficiency. Turning against traffic resulted in long waits in left-hand turn lanes that wasted time and fuel, and it also led to a disproportionate number of accidents. Thus, UPS engineers maped the routes by involving only right turns, creating “The Right Turn Rule”. Only in 2012, UPS saved around 10 million gallons of gas and reduced emissions by the equivalent of taking 5,300 cars of the road for a year, demonstrating that this rule was completely valid.
