As of 2022, there are 41 Rules and four annexes in COLREGs Rules in force. PART A - GENERAL Rule 1 - Application Rule 2 – Responsibility Rule 3 – General Definitions PART B - Section I Conduct of Vessels in any Condition of Visibility Rule 4 – Application Rule 5 – Look-out Rule 6 – Safe Speed Rule 7 – Risk of Collision
Diagram showing principle of constant bearing, decreasing range in marine collision avoidance. When an observer sees another vessel at a constant bearing and the range continually decreases, collision is imminent. A ship seen to be on a constant bearing with decreasing range will collide with the observer's ship unless avoiding action is taken.
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.
April 29, 2024 at 3:30 PM. The Biden administration plans to require that all new cars and trucks come with pedestrian-collision avoidance systems that include automatic emergency braking ...
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 ...
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
When the collision becomes imminent, they can take action autonomously without any driver input (by braking or steering or both). Collision avoidance by braking is appropriate at low vehicle speeds (e.g. below 50 km/h (31 mph)), while collision avoidance by steering may be more appropriate at higher vehicle speeds if lanes are clear.
The Obstacle Collision Avoidance System allows the standard lights to remain off until an aircraft is within a given radius, allowing for a significant decrease in light pollution. The OCAS system also provides audio warnings.
Crash avoidance systems and devices help the driver — and, increasingly, help the vehicle itself — to avoid a collision. This category includes: The vehicle's headlamps, reflectors, and other lights and signals; The vehicle's mirrors; The vehicle's brakes, steering, and suspension systems; Driver assistance
Almost all modern large aircraft are fitted with a traffic collision avoidance system (TCAS), which is designed to try to prevent mid-air collisions. The system, based on the signals from aircraft transponders, alerts pilots if a potential collision with another aircraft is imminent.
