State Route 143 (Arizona)
Arizona State Route 143, also known as SR 143 and the Hohokam Expressway, is a north–south and access-controlled freeway in Maricopa County, Arizona, that runs from a junction with Interstate 10 at 48th Street in Phoenix to McDowell Road. The only other major junction along the route is with Loop 202, which is located one half-mile south of McDowell Road and the northern terminus. The road lies directly to the east of Phoenix Sky Harbor International Airport. Along with the Sky Harbor Expressway (former SR 153), SR 143's primary purpose is to provide East Valley residents with access to Sky Harbor from westbound Interstate 10 and US 60. This removes the need to travel longer on frequently congested I-10 and avoid the junction with Interstate 17's southern terminus. Route description The Hohokam Expressway begins at an intersection with McDowell Road in Phoenix. The freeway continues southward to an ornately designed junction with the Red Mountain portion of Loop 202. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arizona Department Of Transportation
The Arizona Department of Transportation (ADOT, pronounced "A-Dot") is an Arizona state government agency charged with facilitating mobility within the state. In addition to managing the state's state highways, highway system, the agency is also involved with public transportation and airport, municipal airports. The department was created in 1974 when the state merged the Arizona Highway Department with the Arizona Department of Aeronautics. ADOT was a pioneer in the use of rubberized asphalt as a method to increase durability and reduce road noise on state highways while providing an opportunity to tire recycling, recycle scrap tires. Its "Quiet Pavement" project started in 2003 surfaced about of Phoenix-area freeways with rubberized asphalt. Former U.S. Secretary of Transportation Mary Peters (politician), Mary Peters had previously been a Director of ADOT. The current Federal Highway Administrator, Victor Mendez, was also previously a Director of ADOT. ADOT's publications di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chandler, Arizona
Chandler is a city in Maricopa County, Arizona, United States, and a suburb in the Phoenix-Mesa-Chandler Metropolitan Statistical Area (MSA). It is bordered to the north and west by Tempe, to the north by Mesa, to the west by Phoenix, to the south by the Gila River Indian Community, and to the east by Gilbert. As of the 2020 census, the population of Chandler was 275,987, up from 236,123 at the 2010 census. History In 1891, Dr. Alexander John Chandler, the first veterinary surgeon in Arizona Territory, settled on a ranch south of Mesa, studying irrigation engineering. By 1900, he had acquired of land, and began drawing up plans for a townsite on what was then known as the Chandler Ranch. The townsite office opened on May 16, 1912. (Soon after celebrating Chandler's Centennial on May 17, 2012, Chandler Museum staff discovered that the city had been celebrating the wrong date. In May 1912, the ''Chandler Arizonan'' newspaper had erroneously published the founding day as Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloverleaf Interchange
A cloverleaf interchange is a two-level interchange in which all turns are handled by slip roads. To go left (in right-hand traffic; reverse directions in left-driving regions), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road. The objective of a cloverleaf is to allow two highways to cross without the need for any traffic to be stopped by traffic lights. The limiting factor in the capacity of a cloverleaf interchange is traffic weaving. Overview Cloverleaf interchanges, viewed from overhead or on maps, resemble the leaves of a four-leaf clover or less often a 3-leaf clover. In the United States, cloverleaf interchanges existed long before the Interstate system. They were originally created for busier interchanges that the original diamond interchange system could not handle. Their chief advantage was that they were free-flowing and did not require t ...

Rumble Strips
Rumble strips (also known as sleeper lines or alert strips) are a road safety feature to alert inattentive drivers of potential danger, by causing a tactile vibration and audible rumbling transmitted through the wheels into the vehicle interior. A rumble strip is applied along the direction of travel following an edgeline or centerline, to alert drivers when they drift from their lane. Rumble strips may also be installed in a series ''across'' the direction of travel, to warn drivers of a stop or slowdown ahead, or of an approaching danger spot. In favorable circumstances, rumble strips are effective (and cost-effective) at reducing accidents due to inattention. The effectiveness of shoulder rumble strips is largely dependent on a wide and stable road shoulder for a recovery, but there are several other less obvious factors that engineers consider during design. Other names Rumble strips are also known as audible lines, sleepy bumps, wake up calls, growlers, drift lines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strobe Light
A strobe light or stroboscopic lamp, commonly called a strobe, is a device used to produce regular flashes of light. It is one of a number of devices that can be used as a stroboscope. The word originated from the Ancient Greek ('), meaning "act of whirling". A typical commercial strobe light has a flash energy in the region of 10 to 150 joules, and discharge times as short as a few milliseconds, often resulting in a flash power of several kilowatts. Larger strobe lights can be used in “continuous” mode, producing extremely intense illumination. The light source is commonly a xenon flash lamp, or ''flashtube'', which has a complex spectrum and a color temperature of approximately 5,600 kelvins. To obtain colored light, colored gels may be used. Scientific explanation of flashtubes Strobe lights usually use flashtubes with energy supplied from a capacitor, an energy storage device much like a battery, but capable of charging and releasing energy much faster.

Optical
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ac ...

Maricopa Association Of Governments
Maricopa Association of Governments (MAG) is a Council of Governments (COG) that serves as the regional agency for the greater Maricopa region in Arizona, United States. This includes the Phoenix area and the neighboring urbanized area in Pinal County, containing the Town of Florence and City of Maricopa. When MAG was formed in 1967, the elected officials recognized the need for long-range planning and policy development on a regional scale. They realized that many issues such as transportation, air quality and human services affected residents beyond the borders of their individual jurisdictions. MAG is the designated Metropolitan planning organization (MPO) for transportation planning Transportation planning is the process of defining future policies, goals, investments, and spatial planning designs to prepare for future needs to move people and goods to destinations.

Bottleneck (traffic)
A traffic bottleneck is a localized disruption of vehicular traffic on a street, road, or highway. As opposed to a traffic jam, a bottleneck is a result of a specific physical condition, often the design of the road, badly timed traffic lights, or sharp curves. They can also be caused by temporary situations, such as vehicular accidents. Bottlenecks can also occur in other methods of transportation. Capacity bottlenecks are the most vulnerable points in a network and are very often the subject of offensive or defensive military actions. Capacity bottlenecks of strategic importance - such as the Panama Canal where traffic is limited by the infrastructure - are normally referred to as choke points; capacity bottlenecks of tactical value are referred to as mobility corridors. Causes Traffic bottlenecks are caused by a wide variety of things: * Construction zones where one or more existing lanes become unavailable (as depicted in the diagram on the right) * Accident sites that t ...

Traffic Congestion
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or (informally) a traffic snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics. Causes Traffic congestion occurs when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Airport Terminal
An airport terminal is a building at an airport where passengers transfer between ground transportation and the facilities that allow them to board and disembark from an Fixed-wing aircraft, aircraft. Within the terminal, passengers purchase tickets, transfer their luggage, and go through security. The buildings that provide access to the airplanes (via Gate (airport), gates) are typically called concourses. However, the terms "terminal" and "concourse" are sometimes used interchangeably, depending on the configuration of the airport. Smaller airports have one terminal while larger airports have several terminals and/or concourses. At small airports, the single terminal building typically serves all of the functions of a terminal and a concourse. Some larger airports have one terminal that is connected to multiple concourses via walkways, sky-bridges, or tunnels (such as Denver International Airport, modeled after Hartsfield-Jackson Atlanta International Airport, Atlanta's, ...
