A survey was made of the views of trucking companies toward various advanced technologies which fall under the broad concept of Intelligent Vehicle-Highway Systems (IVHS). The survey addressed such issues as voice and data communications between trucks and the fleet dispatcher, modes of presenting messages to the driver, automatic vehicle identification, collision and rollover warning systems, methods of electronic route guidance, systems for monitoring the driver and the vehicle while underway, anti-theft technologies, and means for training drivers to use such advanced technology. The survey addressed details within respective technologies such as the dispatcher's preferences for maximum time between updates on the location of his vehicles and the needed accuracy of such location data. The 96 survey respondents represent a cross-section of trucking operations. The survey sample may be somewhat atypical of the trucking industry, at large, insofar as most of the companies appear to be more-or-less 'early adopters' of innovative technology. The data were analyzed as an aggregate of the overall sample as well as through inter-group comparisons, wherever the statistical quality of the data supported it. The results show a strong interest in many of the IVHS technologies. Interest is high both in the information systems which enhance trucking fleet efficiency and in safety features which help the driver avoid collisions.
