Integrated Vehicle-Based Safety Systems Field Operational Test Final Program Report
Summary Information
This document presents results from the light-vehicle and heavy-truck field operational tests performed as part of the Integrated Vehicle-Based Safety Systems (IVBSS) program. The findings are the result of analyses performed by the University of Michigan Transportation Research Institute to examine the effects of a prototype integrated crash warning system on driver behavior and driver acceptance. Both platforms included three integrated crash-warning subsystems: forward crash; lateral drift; and lane-change/merge crash warnings. The light-vehicle platform also included curve-speed warning.
Findings
- A majority of drivers reported that their driving behavior changed as a result of using the integrated system. The most frequently mentioned change was an increase in turn-signal use, which was the result of receiving lane departure warnings triggered when drivers made unsignaled lane changes.
- While 25 percent of the younger drivers (age 20 to 30) were not interested, 72 percent of all 108 drivers said they would like to have the integrated system in their personal vehicles.
- Drivers found the integrated system's warnings to be helpful and further believed that the integrated system would increase their driving safety.
