Vehicle-Based Safety Systems
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
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.
