Central business district
A central business district is the commercial and business center of a city. In larger cities, it is synonymous with the city's "financial district". Geographically, it coincides with the "city centre" or "downtown", but the two concepts are separate: many cities have a central business district located away from its commercial or cultural city centre or downtown; the CBD is also the "city centre" or "downtown", but this is often not the case. Midtown Manhattan is the largest central business district in the world. For example, London's "city centre" is regarded as encompassing the historic City of London and the mediaeval City of Westminster, whereas the City of London and the transformed Docklands area are regarded as its two CBDs. Mexico City has a historic city centre, the colonial-era Centro Histórico, along with two CBDs: the mid-late 20th century Paseo de la Reforma - Polanco, the new Santa Fe; the shape and type of a CBD always reflect the city's history. Cities with strong preservation laws and maximum building height restrictions to retain the character of the historic and cultural core will have a CBD quite a distance from the centre of the city.
This is quite common for European cities such as Vienna. In cities in the New World that grew after the invention of mechanised modes such as road or rail transport, a single central area or downtown will contain most of the region's tallest buildings and act both as the CBD and the commercial and cultural city center. Increasing urbanisation in the 21st century have developed megacities in Asia, that will have multiple CBDs scattered across the urban area, it has been said. No two CBDs look alike in terms of their spatial shape, however certain geometric patterns in these areas are recurring throughout many cities due to the nature of centralised commercial and industrial activities. In Australia the acronym CBD is used commonly to refer to major city "centres", it is used in particular to refer to the skyscraper districts in state capital cities such as Melbourne, Perth and Sydney. Melbourne is Australia's largest CBD with Sydney second and Brisbane third when judged by area size; the iTowers of Masa Square CBD were built for doing business tasks only.
It is located within Gaborone. In China terms "city centre" are used but a different commercial district outside of the historic core called a "CBD" or "Financial District" may exist. Large Chinese cities have multiple CBDs spread throughout the urban area. Cities traditionally being major cultural centres with many historic structures in the core such as Beijing, Suzhou or Xi'an will have the greenfield CBDs built adjacent to the urban core, similar to European cities. While other cities such as Guangzhou, Shanghai and Wuhan the city centre will house a number of CBDs in addition to greenfield CBDs built in the periphery. In France, the term « quartier d’affaires » may be used to describe the central business district; the main ones business districts in the country are as following: La Défense in Paris, which with 3,300,000 square metres of office space is Europe's leading business district in terms of area. La Part-Dieu in Lyon, is the 2nd largest business district in France and has nearly 1,600,000 square metres.
Euralille in Lille, is the 3rd business district of France with 1,120,000 square metres of offices. Euroméditerranée in Marseille, is the 4th business district in France with 650,000 square metres of offices. In Germany, the terms Innenstadt and Stadtzentrum may be used to describe the central business district. Both terms can be translated to mean "inner city" and "city centre"; some of the larger cities have more than one central business district, like Berlin, which has three. Due to Berlin's history of division during the Cold War, the city contains central business districts both in West and East Berlin, as well as a newly-built business centre near Potsdamer Platz; the city's historic centre — the location of the Reichstag building, as well as the Brandenburg gate and most federal ministries — was abandoned when the Berlin Wall cut through the area. Only after the reunification with the redevelopment of Potsdamer Platz, the construction of numerous shopping centers, government ministries, office buildings and entertainment venues, was the area revived.
In Frankfurt, there is a business district, in the geographical centre of the city and it is called the Bankenviertel. In Düsseldorf, there is a business district, located around the famous High-Street Königsallee with banks and offices. In Hong Kong, Sheung Wan and Causeway Bay are considered as the central business districts of Victoria City; the Yau Tsim Mong District has been considered the city centre of Kowloon before another core emerged in Cheung Sha Wan. As part of the Airport Core Programme, the Union Square project launched by the MTR Corporation has brought it another CBD in West Kowloon. With the latest implementation of "Energising Kowloon East" Scheme by the Hong Kong Government, Kowloon Bay and Kwun Tong Business Area have been redeveloped and transformed into CBDs; the CBDs of new towns and satellite cities such as Tuen Mun, Sha Tin and Tung Chung have been characterised by sky-scraping residential blocks on top of large shopping centres that provide services to local resi
Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product, the sixth largest population, the 25th largest land area of all U. S. states. Illinois is noted as a microcosm of the entire United States. With Chicago in northeastern Illinois, small industrial cities and immense agricultural productivity in the north and center of the state, natural resources such as coal and petroleum in the south, Illinois has a diverse economic base, is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population; the Port of Chicago connects the state to international ports via two main routes: from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean and from the Great Lakes to the Mississippi River, via the Illinois Waterway to the Illinois River. The Mississippi River, the Ohio River, the Wabash River form parts of the boundaries of Illinois. For decades, Chicago's O'Hare International Airport has been ranked as one of the world's busiest airports.
Illinois has long had a reputation as a bellwether both in social and cultural terms and, through the 1980s, in politics. The capital of Illinois is Springfield, located in the central part of the state. Although today's Illinois' largest population center is in its northeast, the state's European population grew first in the west as the French settled the vast Mississippi of the Illinois Country of New France. Following the American Revolutionary War, American settlers began arriving from Kentucky in the 1780s via the Ohio River, the population grew from south to north. In 1818, Illinois achieved statehood. Following increased commercial activity in the Great Lakes after the construction of the Erie Canal, Chicago was founded in the 1830s on the banks of the Chicago River at one of the few natural harbors on the southern section of Lake Michigan. John Deere's invention of the self-scouring steel plow turned Illinois's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden.
The Illinois and Michigan Canal made transportation between the Great Lakes and the Mississippi River valley faster and cheaper, new railroads carried immigrants to new homes in the country's west and shipped commodity crops to the nation's east. The state became a transportation hub for the nation. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois was an important manufacturing center during both world wars; the Great Migration from the South established a large community of African Americans in the state, including Chicago, who founded the city's famous jazz and blues cultures. Chicago, the center of the Chicago Metropolitan Area, is now recognized as a global alpha-level city. Three U. S. presidents have been elected while living in Illinois: Abraham Lincoln, Ulysses S. Grant, Barack Obama. Additionally, Ronald Reagan, whose political career was based in California, was born and raised in the state.
Today, Illinois honors Lincoln with its official state slogan Land of Lincoln, displayed on its license plates since 1954. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago. "Illinois" is the modern spelling for the early French Catholic missionaries and explorers' name for the Illinois Native Americans, a name, spelled in many different ways in the early records. American scholars thought the name "Illinois" meant "man" or "men" in the Miami-Illinois language, with the original iliniwek transformed via French into Illinois; this etymology is not supported by the Illinois language, as the word for "man" is ireniwa, plural of "man" is ireniwaki. The name Illiniwek has been said to mean "tribe of superior men", a false etymology; the name "Illinois" derives from the Miami-Illinois verb irenwe·wa - "he speaks the regular way". This was taken into the Ojibwe language in the Ottawa dialect, modified into ilinwe·.
The French borrowed these forms, changing the /we/ ending to spell it as -ois, a transliteration for its pronunciation in French of that time. The current spelling form, began to appear in the early 1670s, when French colonists had settled in the western area; the Illinois's name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans; the Koster Site demonstrates 7,000 years of continuous habitation. Cahokia, the largest regional chiefdom and urban center of the Pre-Columbian Mississippian culture, was located near present-day Collinsville, Illinois, they built an urban complex of more than 100 platform and burial mounds, a 50-acre plaza larger than 35 football fields, a woodhenge of sacred cedar, all in a planned design expressing the culture's cosmology.
Monks Mound, the center of the site, is the largest Pre-Columbian structure north of the Valley of Mexico. It is 100 feet high, 951 feet long, 836 feet wide, covers 13.8 acres. It contains about 814,000 cubic yards of earth, it was topped by a structure thought to have measured about 105 feet in length and 48 feet in width, covered an area 5,000 square feet, been as much as 50 feet high, making its peak 150 feet above the level of the pl
The kilometre, or kilometer is a unit of length in the metric system, equal to one thousand metres. It is now the measurement unit used for expressing distances between geographical places on land in most of the world. K is used in some English-speaking countries as an alternative for the word kilometre in colloquial writing and speech. A slang term for the kilometre in the US and UK military is klick. There are two common pronunciations for the word; the former follows a pattern in English whereby metric units are pronounced with the stress on the first syllable and the pronunciation of the actual base unit does not change irrespective of the prefix. It is preferred by the British Broadcasting Corporation and the Australian Broadcasting Corporation. Many scientists and other users in countries where the metric system is not used, use the pronunciation with stress on the second syllable; the latter pronunciation follows the stress pattern used for the names of measuring instruments. The problem with this reasoning, however, is that the word meter in those usages refers to a measuring device, not a unit of length.
The contrast is more obvious in countries using the British rather than American spelling of the word metre. When Australia introduced the metric system in 1975, the first pronunciation was declared official by the government's Metric Conversion Board. However, the Australian prime minister at the time, Gough Whitlam, insisted that the second pronunciation was the correct one because of the Greek origins of the two parts of the word. By the 8 May 1790 decree, the Constituent assembly ordered the French Academy of Sciences to develop a new measurement system. In August 1793, the French National Convention decreed the metre as the sole length measurement system in the French Republic; the first name of the kilometre was "Millaire". Although the metre was formally defined in 1799, the myriametre was preferred to the "kilometre" for everyday use; the term "myriamètre" appeared a number of times in the text of Develey's book Physique d'Emile: ou, Principes de la science de la nature, while the term kilometre only appeared in an appendix.
French maps published in 1835 had scales showing myriametres and "lieues de Poste". The Dutch gave it the local name of the mijl, it was only in 1867 that the term "kilometer" became the only official unit of measure in the Netherlands to represent 1000 metres. Two German textbooks dated 1842 and 1848 give a snapshot of the use of the kilometre across Europe - the kilometre was in use in the Netherlands and in Italy and the myriametre was in use in France. In 1935, the International Committee for Weights and Measures abolished the prefix "myria-" and with it the "myriametre", leaving the kilometre as the recognised unit of length for measurements of that magnitude. In the United Kingdom, road signs show distances in miles and location marker posts that are used for reference purposes by road engineers and emergency services show distance references in unspecified units which are kilometre-based; the advent of the mobile phone has been instrumental in the British Department for Transport authorising the use of driver location signs to convey the distance reference information of location marker posts to road users should they need to contact the emergency services.
In the US, the National Highway System Designation Act of 1995 prohibits the use of federal-aid highway funds to convert existing signs or purchase new signs with metric units. The Executive Director of the US Federal Highway Administration, Jeffrey Paniati, wrote in a 2008 memo: "Section 205 of the National Highway System Designation Act of 1995 prohibited us from requiring any State DOT to use the metric system during project development activities. Although the State DOT's had the option of using metric measurements or dual units, all of them abandoned metric measurements and reverted to sole use of inch-pound values." The Manual on Uniform Traffic Control Devices since 2000 is published in both metric and American Customary Units. Some sporting disciplines feature 1000 m races in major events, but in other disciplines though world records are catalogued, the one kilometre event remains a minority event; the world records for various sporting disciplines are: Conversion of units, for comparison with other units of length Cubic metre Metric prefix Mileage Odometer Orders of magnitude Square kilometre Media related to Distance indicators at Wikimedia Commons
An airport is an aerodrome with extended facilities for commercial air transport. Airports have facilities to store and maintain aircraft, a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, includes adjacent utility buildings such as control towers and terminals. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, emergency services. In some countries, the US in particular, they typically have one or more fixed-base operators, serving general aviation. An airport serving helicopters is called a heliport. An airport for use by seaplanes and amphibious aircraft is called a seaplane base; such a base includes a stretch of open water for takeoffs and landings, seaplane docks for tying-up. An international airport has additional facilities for customs and passport control as well as incorporating all of the aforementioned elements.
Such airports rank among the most complex and largest of all built typologies with 15 of the top 50 buildings by floor area being airport terminals. The terms aerodrome and airstrip may be used to refer to airports, the terms heliport, seaplane base, STOLport refer to airports dedicated to helicopters, seaplanes, or short take-off and landing aircraft. In colloquial use in certain environments, the terms airport and aerodrome are interchanged. However, in general, the term airport may imply or confer a certain stature upon the aviation facility that other aerodromes may not have achieved. In some jurisdictions, airport is a legal term of art reserved for those aerodromes certified or licensed as airports by the relevant national aviation authority after meeting specified certification criteria or regulatory requirements; that is to say, all airports are aerodromes, but not all aerodromes are airports. In jurisdictions where there is no legal distinction between aerodrome and airport, which term to use in the name of an aerodrome may be a commercial decision.
In United States technical/legal usage, landing area is used instead of aerodrome, airport means "a landing area used by aircraft for receiving or discharging passengers or cargo". Smaller or less-developed airfields, which represent the vast majority have a single runway shorter than 1,000 m. Larger airports for airline flights have paved runways of 2,000 m or longer. Skyline Airport in Inkom, Idaho has a runway, only 122 m long. In the United States, the minimum dimensions for dry, hard landing fields are defined by the FAR Landing And Takeoff Field Lengths; these include considerations for safety margins during takeoff. The longest public-use runway in the world is at Qamdo Bamda Airport in China, it has a length of 5,500 m. The world's widest paved runway is 105 m wide; as of 2009, the CIA stated that there were 44,000 "... airports or airfields recognizable from the air" around the world, including 15,095 in the US, the US having the most in the world. Most of the world's large airports are owned by local, regional, or national government bodies who lease the airport to private corporations who oversee the airport's operation.
For example, in the United Kingdom the state-owned British Airports Authority operated eight of the nation's major commercial airports – it was subsequently privatized in the late 1980s, following its takeover by the Spanish Ferrovial consortium in 2006, has been further divested and downsized to operating just Heathrow now. Germany's Frankfurt Airport is managed by the quasi-private firm Fraport. While in India GMR Group operates, through joint ventures, Indira Gandhi International Airport and Rajiv Gandhi International Airport. Bengaluru International Airport and Chhatrapati Shivaji International Airport are controlled by GVK Group; the rest of India's airports are managed by the Airports Authority of India. In Pakistan nearly all civilian airports are owned and operated by the Pakistan Civil Aviation Authority except for Sialkot International Airport which has the distinction of being the first owned public airport in Pakistan and South Asia. In the United States, commercial airports are operated directly by government entities or government-created airport authorities, such as the Los Angeles World Airports authority that oversees several airports in the Greater Los Angeles area, including Los Angeles International Airport.
In Canada, the federal authority, Transport Canada, divested itself of all but the remotest airports in 1999/2000. Now most airports in Canada are owned and operated by individual legal authorities or are municipally owned. Many U. S. airports still lease part or all of their facilities to outside firms, who operate functions such as retail management and parking. In the U. S. all commercial airport runways are certified by the FAA under the Code of Federal Regulations Title 14 Part 139, "Certification of Commercial Service Airports" but maintained by the local airport under the regulatory authority of the FAA. Despite the reluctance to privatize airports in the US, the government-owned, contractor-operated arrangement is the standard for the operation of commercial airports in the rest of the world. Airports are divided into airside areas; the landside area is open to the public, while access to the airside area is controlled. The airside area includes all parts of the airpo
General Aviation represents the'private transport' and recreational flying component of aviation. General aviation is the name or term given to all civil aviation aircraft operations with the exception of commercial air transport or aerial work, they are flight activities not involving commercial air transportation of passengers, cargo or mail for remuneration or hire, or an aerial work operation such as agriculture, photography, surveying and patrol, search and rescue, aerial advertisement, etc. It covers certain commercial and private flights that can be carried out under both visual flight and instrument flight rules, such as light aircraft and private jets or helicopters. General aviation thus represents the'private transport' component of aviation; the International Civil Aviation Organization defines civil aviation aircraft operations in three categories: General Aviation, Aerial Work and Commercial Air Transport. The International Council of Aircraft Owner and Pilot Associations includes the following definitions for General Aviation aircraft activities: Corporate Aviation: Company own-use flight operations Fractional Ownership Operations: aircraft operated by a specialized company on behalf of two or more co-owners Business Aviation: self-flown for business purposes Personal/Private Travel: travel for personal reasons/personal transport Air Tourism: self-flown incoming/outgoing tourism Recreational Flying: powered/powerless leisure flying activities Air Sports: Aerobatics, Air Races, Rallies etc.
In 2003 the European Aviation Safety Agency was established as the central EU regulator, taking over responsibility for legislating airworthiness and environmental regulation from the national authorities. Of the 21,000 civil aircraft registered in the UK, 96 percent are engaged in GA operations, annually the GA fleet accounts for between 1.25 and 1.35 million hours flown. There are 28,000 Private Pilot Licence holders, 10,000 certified glider pilots; some of the 19,000 pilots who hold professional licences are engaged in GA activities. GA operates from more than 1,800 airports and landing sites or aerodromes, ranging in size from large regional airports to farm strips. GA is regulated by the Civil Aviation Authority, although regulatory powers are being transferred to the European Aviation Safety Agency; the main focus is on standards of airworthiness and pilot licensing, the objective is to promote high standards of safety. General aviation is popular in North America, with over 6,300 airports available for public use by pilots of general aviation aircraft.
In comparison, scheduled flights operate from around 560 airports in the U. S. According to the U. S. Aircraft Owners and Pilots Association, general aviation provides more than one percent of the United States' GDP, accounting for 1.3 million jobs in professional services and manufacturing. Most countries have authorities that oversee all civil aviation, including general aviation, adhering to the standardized codes of the International Civil Aviation Organization. Examples include the Federal Aviation Administration in the United States, the Civil Aviation Authority in the United Kingdom, Civil Aviation Authority of Zimbabwe in Zimbabwe, the Luftfahrt-Bundesamt in Germany, the Bundesamt für Zivilluftfahrt in Switzerland, Transport Canada in Canada, the Civil Aviation Safety Authority in Australia, the Directorate General of Civil Aviation in India and Iran Civil Aviation Organization in Iran. Aviation accident rate statistics are estimates. According to the U. S. National Transportation Safety Board, in 2005 general aviation in the United States suffered 1.31 fatal accidents for every 100,000 hours of flying in that country, compared to 0.016 for scheduled airline flights.
In Canada, recreational flying accounted for 0.7 fatal accidents for every 1000 aircraft, while air taxi accounted for 1.1 fatal accidents for every 100,000 hours. More experienced GA pilots appear safer, although the relations between flight hours, accident frequency, accident rates are complex and difficult to assess.
