Automotive Collision Avoidance System Field Operational Test

In June of 1999, the National Highway Traffic Safety Administration entered into a cooperative research agreement with General Motors to advance the state-of-the-art of rear-end collision warning technology and conduct a field operational test of a fleet of passenger vehicles outfitted with a prototype rear-end collision warning system and adaptive cruise control.

The goal of the research program was to demonstrate the state-of-the-art of rear-end collision warning systems and measure system performance and effectiveness using lay drivers driving on public roads in the United States.

The five-year program consists of a 2 1/2 year development phase during which refinement of component technologies will continue and be integrated into a prototype test vehicle. In the three-year period of the second program phase, a fleet of ten vehicles will be constructed and outfitted with rear-end collision warning and adaptive cruise control systems and given to volunteer drivers to drive over a period of several weeks. Data collected from on-board vehicle instrumentation will be analyzed and used to estimate potential safety benefits, obtain information on the driving experiences of the volunteer drivers and their acceptance of this next-generation safety technology. The operational test will last approximately one year.

This document reports on the activities and results from the end of the first program year of Phase II of this research project.
