It might seem surprising but 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. And yes, this means that routes are sometimes longer than they could be.
UPS has moved away from trying to find the shortest route and now look at other criteria to optimise the journey. One of their methods is to try and avoid turning through oncoming traffic at a junction.
Although this might be going in the opposite direction of the final destination, it reduces the chances of an accident and cuts delays caused by waiting for a gap in the traffic, which would also waste fuel.
UPS has 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 10m gallons less fuel, emits 20,000 tonnes 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 28.5m miles – despite the longer routes.
Is this the sort of innovative thinking the bus industry could benefit from?
