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 the ...
Survival handbook of the United States Army Air Forces (USAAF) from 1944. Survival, Evasion, Resistance, and Escape (SERE) is a training concept originally developed by the United Kingdom during World War II. It is best known by its military acronym and prepares a range of Western forces to survive when evading or being captured.
Collision avoidance (networking) In computer networking and telecommunication, collision-avoidance methods try to avoid resource contention by attempting to avoid simultaneous attempts to access the same resource. Collision-avoidance methods include prior scheduling of timeslots, carrier-detection schemes, randomized access times, and ...
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. Time-to-collision could be a way to choose which avoidance method (braking or steering) is most appropriate.
Collision avoidance in transportation. 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 ...
a Portable Collision Avoidance System (PCAS) is a less expensive, passive version of TCAS designed for general aviation use. PCAS systems do not actively interrogate the transponders of other aircraft, but listen passively to responses from other interrogations. PCAS is subject to the same limitations as TCAS, although the cost for PCAS is ...
Automotive safety. Crash testing is one of the components of automotive safety. Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design.
The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision ...
