Accident: An incursion that resulted in a collision. Category A: A serious incident in which a collision was narrowly avoided. Category B: An incident in which separation decreases and there is a significant potential for collision, which may result in a time critical corrective/evasive response to avoid a collision. Category C
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.
In aviation, a terrain awareness and warning system ( TAWS) is generally an on-board system aimed at preventing unintentional impacts with the ground, termed "controlled flight into terrain" accidents, or CFIT. [1] The specific systems currently in use are the ground proximity warning system (GPWS) and the enhanced ground proximity warning ...
Traffic collision reconstruction is the process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. Reconstructionists conduct collision analysis and reconstruction to identify the cause of a collision and contributing factors including the role of the driver (s), vehicle (s), roadway and ...
The term active safety (or primary safety) is used in two distinct ways. The first, mainly in the United States, refers to automobile safety systems that help avoid accidents, such as good steering and brakes.
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 ...
Hazard control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following this hierarchy of controls normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced. [1]
A traffic alert and collision avoidance system (TCAS, pronounced / t iː k æ s /; TEE-kas), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft.
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
Overview. The ACD Network is a train-collision prevention system invented by Rajaram Bojji and patented by Konkan Railway Corporation, a public-sector undertaking of the Ministry of Railways, government of India . Anti-collision devices were found to be effective in the Southern Railway zone after a brief trial. [citation needed]
