A traffic alert and collision avoidance system (TCAS, pronounced / t iː k æ s /; TEE-kas), also known as an Airborne Collision Avoidance System (ACAS), [1] is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft.
FLARM is a portmanteau of "flight" and "alarm". The installation of all physical FLARM devices is approved as a "Standard Change", [ 1 ] and the PowerFLARM Core specifically as a "Minor Change" by the European Union Aviation Safety Agency ; [ 2 ] and in addition the Minor Change also approves the PowerFLARM Core for its IFR and at night.
By analyzing traffic patterns, AFADs can intelligently redirect a portion of traffic, reducing congestion and enhancing safety within the construction zone. [ 17 ] [ 18 ] AFADs like the Guardian SmartFlagger can help increase the safety of construction workers, reduce labor costs, increase operational efficiency and driver compliance, while ...
Traffic sign recognition (TSR) systems can recognize common traffic signs, such as a “stop” sign or a “turn ahead” sign, through image processing techniques. [53] This system takes into account the sign's shape, such as hexagons and rectangles, and the color to classify what the sign is communicating to the driver. [53]
Drivers are exempt from the road traffic act with some conditions, [6] however both organisations have policies imposing further restrictions. The siren can be switched off at the discretion of the driver when it is not needed (for example, when the road ahead is clear of traffic and easily visible) and reactivated at possible traffic hazards.
For some traffic safety practitioners, active intelligent speed adaptation is thought to be an example of 'hard automation', an approach to automation that has been largely discredited by the Human Factors community. [citation needed] An inviolable characteristic of human users is that they will adapt to these systems, often in unpredictable ways.
Trailer-mounted variable-message signs are used to alter traffic patterns near work zones, and for traffic management for special events, natural disasters, and other temporary traffic patterns. The messages displayed on the sign can be programmed locally on the unit's control panel, or units equipped with a cellular modem can be programmed ...
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.
