Drivers recommend use of Integrated Vehicle-Based Safety Systems, but price remains a factor.
The IVBSS were introduced into two vehicle fleets: 16 light vehicles and 10 Class 8 tractors. The light vehicles were operated by 108 volunteer drivers for 6 weeks, and the heavy trucks were driven by 18 commercial-truck drivers for a 10-month period. Each vehicle was instrumented to capture detailed data on the driving environment, driver behavior, warning system activity, and vehicle kinematics. Data on driver acceptance was collected through post-drive surveys and debriefings.
Drivers accepted the integrated system and rated it well in terms of both usefulness and satisfaction. Drivers reported that the integrated system’s warnings were helpful and believed it would increase their driving safety.
Overall, drivers stated that the integrated system made them more aware of the traffic environment around their vehicles and their position in the lane, and that integrated crash warning systems would increase their driving safety. Truck drivers responded that they would prefer driving a truck equipped with the integrated warning system to an unequipped, conventional truck (15 of 18 drivers), and would recommend the purchase of such systems (15 of 18 drivers). However, these drivers indicated that they would be willing to pay no more than $750 for such a system.
