The number of IV/HS Commercial Vehicle Operations (CVO) systems may be much larger than what might be expected. When compared to the coverage given to consumer IV/HS demonstrations, the lack of awareness of commercial systems is understandable.In fact, there are hundreds of installations of commercial systems world-wide. While the goals of each application vary with the user, these systems are generically used for Computer-Aided-Dispatching (CAD) and remote access to host computer databases. The system users include police and fire departments, trucking companies, taxi companies, internodal ports, and utilities. These organizations are experiencing the benefits of increased safety, better efficiency, and improved service.CVO systems fundamentally change the way the mobile work force relates to the organization and, in turn, affect the way the organization functions. A brief history of CVO installations, a review of design issues, and user justification will be presented.In addition, those implementing consumer IV/HS systems can learn valuable lessons from previous installations. Although there are distinct differences between commercial and consumer IV/HS, much can be learned about technology and user acceptance.
