Variable Message Sign
A variable- (also changeable-, electronic-, or dynamic-) message sign, often abbreviated VMS, CMS, or DMS, and in the UK known as a matrix sign, is an electronic traffic sign often used on roadways to give travelers information about special events. Such signs warn of traffic congestion, accidents, incidents such as terrorist attacks, AMBER/Silver/Blue Alerts, roadwork zones, or speed limits on a specific highway segment. In urban areas, VMS are used within parking guidance and information systems to guide drivers to available car parking spaces. They may also ask vehicles to take alternative routes, limit travel speed, warn of duration and location of the incidents, inform of the traffic conditions, or display general public safety messages. History VMS systems were deployed at least as early as the 1950s on the New Jersey Turnpike. The NJ Turnpike's signs of that period, and up to around 2012, were capable of displaying a few messages in neon, all oriented around warning ...

New Jersey Turnpike
The New Jersey Turnpike (NJTP) is a system of controlled-access highways in the U.S. state of New Jersey. The turnpike is maintained by the New Jersey Turnpike Authority (NJTA).The Garden State Parkway, although maintained by NJTA, is not considered part of the turnpike. The mainline's southern terminus is at a complex interchange with Interstate 295 (I-295), U.S. Route 40 (US 40), US 130, and Route 49 near the border of Pennsville and Carneys Point townships in Salem County, east of the Delaware Memorial Bridge. Its original northern terminus was at an interchange with I-80 and US 46 in Ridgefield Park, Bergen County; the turnpike was later extended to the George Washington Bridge and New York City. Construction of the mainline from concept to completion took 23 months, from 1950 to 1952. It was officially opened to traffic on November 5, 1951, between its southern terminus and exit 10. The turnpike is a major thoroughfare prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LED Display
A LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes. LED displays can offer higher contrast ratios than a projector and are thus an alternative to traditional projection screens, and they can be used for large, uninterrupted (without a visible grid arising from the bezels of individual displays) video walls. microLED displays are LED displays with smaller LEDs, which poses significant development challenges. History Light-emitting diodes (LEDs) came into existence in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flip-disc Display
The flip-disc display (or flip-dot display) is an electromechanical dot matrix display technology used for large outdoor signs, normally those that will be exposed to direct sunlight. Flip-disc technology has been used for destination signs in buses across North America, Europe and Australia, as well as for variable-message signs on highways. It has also been used extensively on public information displays.Norman Ball, John Vardalas"Ferranti-Packard" McGill Queen's Press, 1994, A few game shows have also used flip-disc displays, including Canadian shows like ''Just Like Mom'', ''The Joke's on Us'' and '' Uh Oh!'', but most notably the American game show ''Family Feud'' from 1976 to 1995 and its British version ''Family Fortunes'' from 1980 to 2002. The Polish version of Family Feud, Familiada, still uses this board, which was bought from the Swedish version of the show. In 2012, Brooklyn-based artist studio, BREAKFAST, began engineering a modernized Flip-Disc technology whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber Optic Display
A fiber-optic display is a light-emitting display that uses fiber optics to display images or text. Fiber-optic displays can either be static or dynamic, with the typical lighting source being halogen light bulbs. Static fiber optic displays Static fiber optic displays have been commonly used for some types of traffic signals. One common use for static fiber optic displays are lane control lights, which display either a green downward-pointing arrow or a red X to indicate the open/closed status of road lanes. Dynamic fiber optic displays Dynamic fiber optic displays typically display alphanumeric text, and utilize electromechanical shutters to open or close the ends of the fiber strands to display an alphanumeric pixel. These type of displays were commonly used as variable-message signs on highways. Compared to eggcrate displays, dynamic fiber optic displays offered lower energy consumption due to requiring fewer bulbs, and offered improved nighttime legibility. For daytim ...

Eggcrate Display
A text display is an electronic alphanumeric display device that is mainly or only capable of showing text, or extremely limited graphic characters. This includes electromechanical split-flap displays, vane displays, and flip-disc displays; all-electronic liquid-crystal displays, incandescent eggcrate displays, LED displays, and vacuum fluorescent displays; and even electric nixie tubes. There are several ways to form text for display. A segment display uses lines, while a dot-matrix display uses a grid of dots, and both of these are seen in LCD, LED, VFD, and vane/disc types. For split-flap displays, the characters or words are pre-printed, and for nixie tubes the shapes are also pre-formed. In any case, the display elements are controlled by electronics which activate them in the correct physical and temporal sequence to show the desired information. Text displays are used in everything from clocks (clock radios, wristwatches) to variable-message signs ( departure board ...

Trilon
A trilon is a three-faceted prism-shaped object. A trilon can be made to rotate on an axle to show different text or images which may be applied to any of its three facets. Trilons have been used on game shows and billboards. The game board on the original ''Concentration'' may have been the first use of trilons on a game show. The game combined the card game with a rebus puzzle. The original game board consisted of 30 motorized trilons. One facet of each trilon had an identifying number. A description of a prize or other game element was on a second facet, and a portion of a rebus was on the third facet. The rebus was gradually revealed as the game progressed. Puzzle pieces were kept under high security and were attached to the trilons only as needed. Trilons became a common element on many other game (and reality) shows including: *'' Three on a Match'', which used a board with three columns of four trilons each, but unlike ''Concentration'', these trilons rotated vertical ...

400-series Highways
The 400-series highways are a network of controlled-access highways throughout the southern portion of the Canadian province of Ontario, forming a special subset of the provincial highway system. They are analogous to the Interstate Highway System in the United States or the Autoroute system of neighbouring Quebec, and are regulated by the Ministry of Transportation of Ontario (MTO). The 400-series designations were introduced in 1952, although Ontario had been constructing divided highways for two decades prior. Initially, only Highways 400, 401 and 402 were numbered; other designations followed in the subsequent decades. Modern 400-series highways have high design standards, speed limits of , with a limit on select stretches, and various collision avoidance and traffic management systems. The design of 400-series highways has set the precedent for a number of innovations used throughout North America, including the parclo interchange and a modified Jersey barrier ...

Tule Fog
Tule fog () is a thick ground fog that settles in the San Joaquin Valley and Sacramento Valley areas of California's Central Valley. Tule fog forms from late fall through early spring (California's winter season) after the first significant rainfall. The official time frame for tule fog to form is from November 1 to March 31. This phenomenon is named after the tule grass wetlands (''tulares'') of the Central Valley. Tule fog is the leading cause of weather-related accidents in California. Formation Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude. In California, tule fog can extend from Bakersfield to Red Bluff, covering a distance of over . Tule fog occasionally drifts as far west as the San Francisco ...

California State Route 120
State Route 120 (SR 120) is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season. Route description SR 120 begins as a freeway intersecting Interstate 5 to extend Interstate 205 through Manteca. In east Manteca the freeway ends at SR 99 and becomes a highway which continues to head east through Escalon, Oakdale and other various small towns. East of Oakdale there are no highly populated ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
