The automotive  industry has  made significant  progress in  the development  of
advanced  technologies intended to  prevent crashes and  their consequences.
Advanced vehicle-based technologies that include sensing, computing, and
communications  may  have  the  ability  to  help  drivers  avoid  imminent
positioning, crashes or events that  often lead to crashes  and to  reduce
the  severity  of  crashes that do  occur.  For example,  some of  these
technologies  address  goals  such as  preventing  forward  collisions,
lane departures, and head-on collisions.

A major emphasis of the NHTSA Crash Avoidance Research program
is to  understand  the  effectiveness  of  advanced  technology  safety
systems in  reducing crashes.  NHTSA  seeks to answer the following
  1. What  emerging or foreseeable  advanced  technology  applications
    may  help  drivers  avoid  a  crash,  or  may  reduce  crash  severity  and
    prevent injuries when one occurs?
  2. How effective will the selected  technologies  be  in  preventing  crashes  and
    reducing their severity and protecting vehicle occupants?
  3. Can performance specifications be defined based on the crash situations in which
    these technologies work?
  4. Can test procedures be developed that objectively measure conformance with the performance specification?
Vehicle-Based Safety Systems
For the past 15 years NHTSA has been engaged in research related to on-board crash warning systems that detect potential crash situations and warn the driver to take appropriate action. Such systems include forward collision warning (FCW); lane departure warning (LDW); and blind spot monitoring (BSM). Past research has included evaluations of prototype systems in both controlled settings (test track and simulators), and through field testing. For example, in 2010 NHTSA concluded an Integrated Vehicle Based Safety Systems (IVBSS) study that included all of these warning technologies (FCW, LDW and BSM). The results of the study, which included 16 vehicles and 108 drivers, showed such technologies offer significant promise for enhancing vehicle safety.
