If you ran a delivery business, you might intuitively imagine that your delivery route optimization algorithm should optimize for the shortest route to the destination.
UPS, however, moved away from trying to find the shortest route. Instead, they avoid turning through oncoming traffic at a junction. This “no left turn” (in countries with right handed traffic) rule may mean going in the opposite direction of the final destination. However, it reduces the chances of an accident and cuts delays caused by waiting for a gap in the traffic, which wastes fuel.
This simple idea means the company saves 10 million gallons less fuel, emits 20,000 tonnes less carbon dioxide, while delivering 350,000 more packages every year. (Mythbusters confirmed this in a test)
Prof Kendall, writing on Quartz, asks – could we plan roads that make it more difficult to turn through the traffic? It would take a brave city planner to implement this, but if UPS can save 10 million gallons of fuel, how much could a whole city or even a whole country save?
The success of UPS’s policy raises the question, why don’t we all avoid turning left (or right, depending on what country we’re in), as we drive around cities on our daily commutes? If everyone did it, the carbon savings would be huge and there’d probably be far less congestion. – Prof Kendall on Quartz

This post is part of “The 200 words project.” I aim to synthesize a story from a book (and, occasionally a blog or article) I’ve read within 200 words consecutive Sundays for around 45 weeks of the year. I’ve also recently started a new Sunday project that synthesizes 5 things you need to know about tech this week – if you’re interested, more on that on NotesbyAda.com.
