maintain log books, and collect tolls. The variety of regulations and reporting needs of CVO requires increased information processing by the operators. Human factors investigations addressing the combination of cognitive and physical workloads involved, as well as possible ITS-related solutions, are required.
Fleet management is concerned with the timeliness and reliability of commercial carriers. ITS technologies in this area are likely to include automatic vehicle tracking and in-vehicle routing displays. Navigation and route guidance systems for CVO must accommodate specific routing regulations governing the weight, size, and cargo of the vehicle. In-vehicle displays for CVO will present more information than similar displays in personal vehicles. Furthermore, the physical environment of a truck cab including the windshield design, and the excessive noise and vibrations, present unique human factors challenges for the design of in-vehicle displays.
Many ITS technologies are designed to improve CVO safety, including ODAS, warning systems for load shifts, and impending vehicle rollover messages on freeway ramps. Driver impairment issues due to fatigue and other factors are critical in the CVO area. Human factors research will determine the optimal methods for providing safety information to CVO drivers. Furthermore, methods of detecting possible safety problems before they become emergencies, such as driver fatigue or excessive speed, will require significant human factors investments.
