Not so long ago, UPS drivers worked off maps, 3-x-5 note cards, and their own memory to figure out the best way to run their routes. That changed in 2005 when UPS began to implement a $600 million route optimization system--think MapQuest on steroids--that each evening maps out the next day's schedule for the majority of its 56,000 drivers. So sophisticated is the software that it designs each route to minimize the number of left turns, thus reducing the time and gas that drivers waste idling at stoplights.
