The objective of this research is to understand how managers of trucking companies perceive the benefits of different types of information that could be delivered to drivers using internet-enabled wireless devices. The types of information the authors investigated could be offered as part of a comprehensive advanced traveler information system (ATIS). Examples include: locations of freeway incidents and lane closures, port and rail terminal schedules and clearances, delays (queue lengths) at terminals, port facilities and international border crossings, train arrivals at grade crossings, weather, and travel times on alternative routes. Such information could be used by drivers and also by dispatchers and managers to improve efficiency through adjustments in routes and schedules. They applied a structural equation model (SEM) to attitudinal data from a large-scale survey of for-hire trucking companies and private trucking fleets operating in California. The model describes how perceptions of the value of specific sources of traffic information are related to the operating characteristics of the trucking companies. Results showed that information delivered using new internet-enabled in-vehicle or hand-held devices is valued differently by managers of trucking companies with different types of operations. These findings are consistent with earlier studies have shown that different segments of the trucking industry value simple traffic information differently.
