IT hits the highway: Big rigs go high tech

Another option is BLU, a Windows CE-based handheld offered by PeopleNet Communications, includes a touch-screen interface and a range of applications -- including one that allows the driver to immediately scan documents and signatures and transmit them over a cellular link, rather than using a fax machine at the next truck stop.

J.B. Hunt's system captures both bar codes and proof-of-delivery signatures. Information is uploaded from the vehicle every 15 minutes via cellular or Wi-Fi connectivity. "We put it on the Web within minutes" so customers can then view it, says Palmer.

Electronic driver logs

prevent drivers from working more than 14 hours and driving more than 11 hours per day. Drivers must then rest for 10 hours before resuming. "That tractor can only move 11 out of 24 hours, and that's best case," says Palmer, so maximizing productivity is vital.

Most large carriers still rely on having drivers fill out paper logbooks to document their hours of service, a system that makes it easy for drivers to fudge the amount of time they've spent behind the wheel. If drivers get caught breaking the rules, their carriers can be hit with substantial fines, and multiple violations can lead to a downgraded safety rating. When overtired drivers who break the rules are involved in accidents, carriers may suffer large liability judgments and lots of bad publicity.
