In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. [3]
Speed warning systems are designed to alert the driver of the vehicle when they have exceeded the speed limit. To do this, GPS technologies are used to triangulate the vehicle's location; along with a record of speed limits in the area, the system uses built-in speed sensors to notify the driver when they exceed the speed limit. If the list of ...
A 2015 Insurance Institute for Highway Safety study found forward collision warning and automatic braking systems reduced rear collisions. [ 37 ] A 2015 study based on European and Australasian data suggests the AEB can decrease rear-end collisions by 38%.
Nowadays, however, this area contains highly advanced systems such as anti-lock braking system, electronic stability control and collision warning/avoidance through automatic braking. This compares with passive safety (or secondary safety), which are active during an accident.
Forward collision warning (FCW) monitor the speed of the vehicle and the vehicle in front of it, and the open distance around the vehicle. [21] FCW systems will send an alert to the driver of a possible impending collision if gets too close to the vehicle in front of it. [21] These systems do not take control of the vehicle, as currently, FCW ...

A simple collision avoidance system. In transportation, collision avoidance is the maintenance of systems and practices designed to prevent vehicles (such as aircraft, motor vehicles, ships, cranes and trains) from colliding with each other. They perceive the environment with sensors and prevent collisions using the data collected from the sensors.
In the US 49/563.5 regulatory framework, Event data recorder is defined as a . a device or function in a vehicle that records the vehicle's dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval after the crash event.
