UPS has gotten significant press for their use of software to maximise efficiency in their route planning. (See this New York Times article) The article claims that through efficient route planning, including the elimination or minimization of left hand turns, they have had some astonishing results.
the software helped the company shave 28.5 million miles off its delivery routes, which has resulted in savings of roughly three million gallons of gas and has reduced CO2 emissions by 31,000 metric tons.
At $3 a gallon for fuel, that's $9 million in savings. I wonder what it cost to implement?
How cool would it be if this was a feature in Google Maps or a GPS unit? You enter all the errands you need to do in a day, in any order, and it spits out the most fuel efficient and time efficient options, especially if it took traffic data into account.
