  3. Collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Collision_avoidance_system

    A collision avoidance system ( CAS ), also known as a pre-crash system, forward collision warning system ( FCW ), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. [2] In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of ...

    en.wikipedia.org/wiki/Traffic_collision

    A traffic collision, also known as a motor vehicle collision ( car crash in case cars are involved in the collision), occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and ...

  6. Ground proximity warning system - Wikipedia

    en.wikipedia.org/wiki/Ground_proximity_warning...

    A ground proximity warning system ( GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). [1] More advanced systems, introduced in 1996, [2] are ...

  7. Traffic collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Traffic_collision...

    A traffic alert and collision avoidance system ( TCAS, pronounced / tiːkæs /; TEE-kas ), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air ...

    According to Euro NCAP, AEB has three characteristics: [5] Autonomous: the system acts independently of the driver to avoid or mitigate the accident. Emergency: the system will intervene only in a critical situation. Braking: the system tries to avoid the accident by applying the brakes.

  11. Airborne collision avoidance system - Wikipedia

    en.wikipedia.org/wiki/Airborne_collision...

    An airborne collision avoidance system ( ACAS, usually pronounced as ay-kas) operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision. If the risk of collision is imminent, the system recommends a maneuver that will reduce the risk of ...

  12. Collision avoidance in transportation - Wikipedia

    en.wikipedia.org/wiki/Collision_avoidance_in...

    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. Examples include: Airborne collision avoidance systems for aircraft. Automatic Identification System for collision avoidance in water transport.
