After a few time-consuming detours, trucking and logistics company Schneider National Inc. is implementing a tracking system that will let shipping customers know at all times where a trailer is and whether it's loaded or unloaded. That means a retailer will be able to track not only when a shipment arrives at a particular store, but also when it's unloaded. That can make for more-precise logistics and more-efficient utilization of trailers and drivers. The service, which relies on the cellular network to relay information, will likely be available by the middle of 2004. Schneider has been trying to implement such a system for several years, since surveys show more than two-thirds of its customers want this data. It hasn't been able to deliver the service because vendors didn't have the technology needed to make it work.
