UPS DRIVERS * USA: "Why don’t we all avoid turning left?"
* New York - UPS drivers don’t turn left—and it saves them 10 million gallons of gas a year
(Video from GeoBeats News - Apr 10, 2014 - While an individual person may not save much by only making right turns, a huge corporation like UPS has proven since 2004 how avoiding left turns in its trucks can significantly increase its bottomline while)
--- UPS delivery vans don’t always take the shortest route between stops. The company gives each driver a specific route to follow and that includes a policy that drivers should never turn through oncoming traffic (that’s left in countries where they drive on the right and vice versa) unless absolutely necessary. This means that routes are sometimes longer than they have to be. So, why do they do it? ... UPS have designed their vehicle routing software to eliminate as many left-hand turns as possible (in countries with right-hand traffic). Typically, only 10% of the turns are left turns. As a result, the company claims it uses 10 million gallons less fuel, emits 20,000 tonnes (22,000 tons) less carbon dioxide, and delivers 350,000 more packages every year. The efficiency of planning routes with its navigation software this way has even helped the firm cut the number of trucks it uses by 1,100, bringing down the company’s total distance travelled by 28.5 million miles—despite the longer routes... It seems incredible that not turning left can lead to such significant savings... So, if you cannot persuade people, it might be down to governments to encourage or even enforce the strategy. For example, we could 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?... ...
