Yellow Trap
The yellow trap is a type of road traffic situation that may arise at certain signalized intersections, involving straight-moving traffic conflicting with turning, crossing traffic, that has made an erroneous assumption that the conflict has been resolved, based on '' their'' received traffic signal. The name ''yellow trap'' originates from the fact that drivers who receive a yellow (also known as ''amber'') Variations in traffic light operation#Steady green arrows, permissive turn signal, may erroneously believe that the conflicting, straight-moving traffic has also received a yellow cue, when in fact, the straight-moving signal is still green. It can present a potentially dangerous scenario relating to turns at a traffic light, traffic-light–controlled intersection across oncoming traffic without a Variations in traffic light operation#Steady green arrows, protective turn signal; for right- and left-hand traffic, right-hand traffic, this refers to a vehicle attempting to make ...

Variations In Traffic Light Operation
In traffic engineering, there are regional and national variations in traffic light operation. This may be in the standard traffic light sequence (such as the inclusion of a red–amber phase) or by the use of special signals (such as flashing amber or public transport signals). Flashing signals Flashing red In the United States and Canada, a flashing red light is the equivalent of a stop sign. In New Zealand, Hong Kong, and the United Kingdom, paired red/red traffic lights are often installed outside fire and ambulance stations on major roads, which, when activated by the station, flash alternately (so that at any time one red light is showing), the purpose being to cause traffic to stop for a set amount of time to allow emergency vehicles to exit their station safely. The UK also uses an amber light which precedes the flashing red lights, and these signals are also used at level crossings, airfields and lifting bridges.

Traffic Light
Traffic lights, traffic signals, or stoplights – also known as robots in South Africa, Zambia, and Namibia – are signaling devices positioned at intersection (road), road intersections, pedestrian crossings, and other locations in order to control the flow of traffic. Traffic lights usually consist of three signals, transmitting meaningful information to road users through colours and symbols, including arrows and bicycles. The usual traffic light colours are red to stop traffic, Amber (color), amber for traffic change, and green to allow traffic to proceed. These are arranged vertically or horizontally in that order. Although this is internationally standardised, variations in traffic light sequences and laws exist on national and local scales. Traffic lights were first introduced in December 1868 on Parliament Square in London to reduce the need for police officers to control traffic. Since then, electricity and computerised control have advanced traffic light technolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right- And Left-hand Traffic
Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side or to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the '' rule of the road''. The terms right- and left-hand ''drive'' refer to the position of the driver and the steering wheel in the vehicle and are, in automobiles, the reverse of the terms right- and left-hand ''traffic''. The rule also includes where on the road a vehicle is to be driven, if there is room for more than one vehicle in one direction, and the side on which the vehicle in the rear overtakes the one in the front. For example, a driver in an LHT country would typically overtake on the right of the vehicle being overtaken. RHT is used in 165 countries and territories, mainly in the Americas, Continental Europe, most of Africa and mainland Asia (except South Asia and Thailand), while 75 countries use LHT, which account for about a ...

Right-of-way (traffic)
Traffic is the movement of vehicles and pedestrians along land routes. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. ( International Regulations for Preventing Collisions at Sea govern the oceans and influence some laws for navigating domestic waters.) Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, cones, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' co ...

Yellow Trap Without Text
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet). Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual On Uniform Traffic Control Devices
The ''Manual on Uniform Traffic Control Devices for Streets and Highways'' (usually referred to as the ''Manual on Uniform Traffic Control Devices'', abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed, and used. Federal law requires compliance by all traffic control signs and surface markings on roads "open to public travel", including state, local, and privately owned roads (but not parking lots or gated communities). While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD. The MUTCD defines the content and placement of traffic signs, while design specifications are detailed in a companion volume, ''Standard Highway Signs and Markings''. This manual defines the specific dimensions, colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
