Collision avoidance in transportation explained

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:

Uses

In aviation

Unmanned Aerial Vehicles use collision avoidance systems to operate safely.[2] TCAS is a collision avoidance system that is widely used.[3] It is a universally accepted last resort meant to reduce the chance of collisions.[4]

In autonomous driving

See main article: page and Collision avoidance system. Collision avoidance is also used in autonomous cars.[5] The aim of a collision avoidance system in vehicles is to prevent collisions, primarily caused by negligence or blind spots, by developing safety measures.

In trains

Automatic Train Protection, an important function of a train control system, helps prevent collisions by managing the speed of the train.[6]

In ships and other water transport

Automatic identification systems are used for collision avoidance in water transport.[7]

Examples of usage

Types

Depending on when they are deployed, collision avoidance systems can be classified into two types, passive and active.[9]

Passive methods

Methods of collision avoidance like seatbelts and airbags are primarily designed to reduce injury to the driver. They are passive methods of collision avoidance. This includes rescue systems that notify rescue centers of an accident.

Active methods

With the addition of camera and radar sensing technologies, active collision avoidance methods can assist or warn the driver, or take control in dangerous situations.
