A recent article in the New York Times talks about how UPS is using software to automate the routes that the trucks take. Doesn’t sound like anything new, however the routes that are selected eliminate as many left turns a possible. Eliminating left turns saves on gas and thus money as well as emissions for the company as the trucks must sit and idle while waiting for traffic to clear before turning. This is fairly ingenious, as long as they make sure to keep those left hand turns that would otherwise cause the route to increase the distance enough to negate any savings that they had by eliminating them in the first place. Anyway, I just enjoy seeing software being put to good use.
