Michigan experience with Integrated Vehicle-Based Safety Systems (IVBSS)

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.

During the field operational test (FOT), 108 drivers drove 16 FOT vehicles for 40 days, 12 days of baseline period of driving without the integrated safety system activated and 28 days of driving with the IVBSS activated. The data collected represents 213,309 miles, 22,657 trips, and 6,164 hours of driving.

Findings
  • Eight drivers reported that the integrated system prevented them from having a crash.
  • The integrated system had a statistically significant effect on the frequency of lane departures, decreasing the rate from 14.6 departures per 100 miles during baseline driving to 7.6 departures per 100 miles during the treatment condition.
