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 (LDW); and lane-change/merge crash (LCW) warnings. The light-vehicle platform also included curve-speed warning.
Implement location-based filtering to modify threat assessments or alerts where drivers choose not to respond to repeated in-vehicle warnings. Invalid warnings occurred in both the light vehicle and heavy vehicle platform testing, especially for fixed objects outside the vehicle's path.
