LOUISVILLE, Ky. (WDRB) -- It's just another day for UPS driver Mark Casey. He has 60 miles to drive, and 125 deliveries to make.

Casey has been driving in Louisville for 30 years. He says not much has changed in those three decades: he still wears a brown uniform, drives a big brown truck, and follows almost the same safety routine he's followed since Day One.

He may not notice it in his day-to-day routine, but UPS has made some changes in recent years. Although the aesthetics and operations of the trucks remain the same, on-board computers are improving efficiency.

While a sophisticated computer program plugs in delivery addresses and maps out each driver's daily route, another program monitors the drivers' movements in the truck.

"Everything the driver does is being measured," explained Jason Pierce, business manager of the Louisville centennial hub.

UPS is using two key software systems to achieve ultimate efficiency. ORION is the computer system that designs optimized delivery routes, while Telematics measures movements inside each truck.

"[Orion] is communicating back all day long where they're at and what they've got done," said Pierce. "On the other side of that, is Telematics, which is telling us about seatbelts, about how many times they back [up], whether they are using the DIAD board while their package car is on, or if they're driving when they have the bulkhead door open."

Casey said he doesn't mind "big brother" always watching, as he's confident he's doing everything as quickly and safely as possible.

"We've got methods that we use, so if you do the methods, you don't really worry about it," he said. "You follow the methods, it's just part of the job."

The software additions were added a few years after UPS announced it would exclusively make right turns when the route allowed for it. The company said it was not only safer, but more efficient to only make left turns when absolutely necessary.

"It's always quicker to make a right and another right than a left across traffic and have to wait for both sides of traffic," said Casey.

Casey said there are exceptions, but if given a choice, he'll always go right.
