Summary Information

Crash avoidance technologies such as lane change assist and automatic braking are increasingly popular technologies in cars. However, few studies have quantified their potential benefits.

Researchers from Carnegie Mellon University quantified the potential benefits from driver assistance vehicle technologies using National Highway Transportation Safety Administration (NHTSA) data. Specifically, the NHTSA estimates the number and "crash characteristics" of automobile accidents in the United States. They then classified all accidents as potentially being preventable by three specific driver assistance technologies namely blind spot monitoring, lane departure warning, and forward collision warnings.

Findings:
  • Driver Assistance vehicle technologies could potentially save $36.7 billion USD per year
  • Much of the potential savings come from reduced crash severity leading to less medical cost burdens
  • These technologies could prevent 1.6 million crashes and 7,200 fatal crashes per year.
