Front-to-rear crashes can be prevented by countermeasure which can be used effectively by proven Automatic emergency braking method so that the estimated potential can be lived fully.
In US, rear-end crashes were notified as high as per a report by Insurance Institute for Highway Safety. The warning system that estimated forward collision where drivers get warned by rear-end crashes are imminent, if the potential collision is not responded by drivers where brakes may be automatic end up preventing 70% of front- to- rear crashes.
Automatic emergency braking proved to reduce the front impact crashes by 27% and rear-end crashes by 27-50% and also to claim the insurance rate for covering damage have been reduced. Even then there are various factors which could lead to diminishing technologies related to crash avoidance.
If the system is not been used by the drivers and the technology is turned off, then it contributes in creating one of the factors in crash. If there are limitations in current sensing technology, there may be constraints on how well AEB (Automatic Emergency Braking) responds. One of the benefits of AEB technology is that it is not a human dependent technology, where it is activated only when it gets a signal from drivers but the severity of the crash can be eased out by emergency brake system.
To issue warnings, trusting drivers and warning criticality to be perceived prior to any experiences are some major factors that affects drivers responding to warning to forward collisions.
