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 ...
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 ...
2002 Überlingen mid-air collision. In aviation, a mid-air collision is an accident in which two or more aircraft come into unplanned contact during flight. [1] Owing to the relatively high velocities involved and the likelihood of subsequent impact with the ground or sea, very severe damage or the total destruction of at least one of the ...
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 ...
The crash happened around 4:30 p.m. Monday, May 6, in a Port Richey residential neighborhood, about a 40-mile drive northwest of Tampa. “A Mercury sedan, driven by a 87-year-old Port Richey ...
Carrier-sense multiple access with collision avoidance ( CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". [1] [2] When they do transmit, nodes transmit their packet data in its ...
A portable collision avoidance system (PCAS) is an aircraft collision avoidance system similar in function to traffic collision avoidance system (TCAS). TCAS is the industry standard for commercial collision avoidance systems but PCAS is gaining recognition as an effective means of collision avoidance for general aviation and is in use the world over by independent pilots in personally owned ...
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.
