Delhi (; ''Dillī''; ''Dillī''; ''Dêhlī''), officially the National Capital Territory (NCT) of Delhi, is a city and a union territory of India containing New Delhi, the capital of India. * * * It is bordered by the state of Haryana on three sides and by Uttar Pradesh to the east. The NCT covers an area of . According to the 2011 census, Delhi's city proper population was over 11 million,Delhi Metropolitan/City Population section of the second-highest in India after Mumbai, while the whole NCT's population was about 16.8 million. Delhi's urban area is now considered to extend beyond the NCT boundaries, and include the neighbouring satellite cities of Ghaziabad, Faridabad, Gurgaon and Noida in an area called the National Capital Region (NCR) and had an estimated 2016 population of over 26 million people, making it the world's second-largest urban area according to the United Nations. Recent estimates of the metro economy of its urban area have ranked Delhi either the most or second-most productive metro area of India. Delhi is the second-wealthiest city in India after Mumbai and is home to 18 billionaires and 23,000 millionaires. Delhi ranks fifth among the Indian states and union territories in human development index. Delhi has the second-highest GDP per capita in India. Delhi is of great historical significance as an important commercial, transport, and cultural hub, as well as the political centre of India.—

— Delhi is one of the oldest cities in the world, and has been continuously inhabited since the 6th century BCE. Through most of its history, Delhi has served as a capital of various kingdoms and empires, most notably the Pandavas, the Tomars, the Slave dynasty and the Mughals. The city has been captured, ransacked and rebuilt several times, particularly during the medieval period, and modern Delhi is a cluster of a number of cities spread across the metropolitan region. For many centuries Delhi has been a dominant trading and commercial centre in northern India, and after 1990s it has emerged as an important node in the international corporate and financial network.—
—
— A union territory, the political administration of the NCT of Delhi today more closely resembles that of a state of India, with its own legislature, high court and an executive council of ministers headed by a Chief Minister. New Delhi is jointly administered by the federal government of India and the local government of Delhi, and serves as the capital of the nation as well as the NCT of Delhi. Delhi hosted the inaugural 1951 Asian Games, 1982 Asian Games, 1983 NAM Summit, 2010 Men's Hockey World Cup, 2010 Commonwealth Games, 2012 BRICS Summit and was one of the major host cities of the 2011 Cricket World Cup. Delhi is also the centre of the National Capital Region (NCR), which is a unique 'interstate regional planning' area created by the National Capital Region Planning Board Act of 1985.


Toponym

There are a number of myths and legends associated with the origin of the name ''Delhi''. One of them is derived from ''Dhillu'' or ''Dilu'', a king who built a city at this location in 50 BCE and named it after himself. Another legend holds that the name of the city is based on the Hindi/Prakrit word (''loose'') and that it was used by the Tomaras to refer to the city because the iron pillar of Delhi had a weak foundation and had to be moved. According to Panjab Notes and Queries, the name of the city at the time of King Prithviraj was , and that and are probably derived from the old Hindi word meaning "eminence". The former director of the Archaeological Survey of India, Alexander Cunningham, mentioned that later became . Some suggest the coins in circulation in the region under the Tomaras were called ''dehliwal''. According to the Bhavishya Purana, King Prithiviraja of Indraprastha built a new fort in the modern-day Purana Qila area for the convenience of all four castes in his kingdom. He ordered the construction of a gateway to the fort and later named the fort ''dehali''.Delhi City
The Imperial Gazetteer of India, 1909, v. 11, ''p. 236.''. Some historians believe that ''Dhilli'' or ''Dhillika'' is the original name for the city while others believe the name could be a corruption of the Hindustani words ''dehleez'' or ''dehali''—both terms meaning "threshold" or "gateway"—and symbolic of the city as a gateway to the Gangetic Plain. The people of Delhi are referred to as ''Delhiites'' or ''Dilliwalas''. The city is referenced in various idioms of the Northern Indo-Aryan languages. Examples include: * ''Abhī Dillī dūr hai'' (अभी दिल्ली दूर है) or its Persian version, ''Hanuz Dehli dur ast'' (), literally meaning "Delhi is still far away", which is generically said about a task or journey still far from completion. * (दिल्ली दिलवालों का शहर) or (दिल्ली दिलवालों की), meaning "Delhi belongs to the large-hearted/daring". * (आस-पास बरसे, दिल्ली पानी तरसे), literally meaning "It pours all around, while Delhi lies parched". An allusion to the sometimes semi-arid climate of Delhi, it idiomatically refers to situations of deprivation when one is surrounded by plenty.


History




Ancient and Early Medieval Periods

The area around Delhi was probably inhabited before the second millennium BCE and there is evidence of continuous inhabitation since at least the 6th-century BCE. The city is believed to be the site of Indraprastha, the legendary capital of the Pandavas in the Indian epic ''Mahabharata''. According to the Mahabharata, this land was initially a huge mass of forests called 'Khandavaprastha' which was burnt down by the Pandavas to build the city of Indraprastha. The earliest architectural relics date back to the Maurya period (c. 300 BCE); in 1966, an inscription of the Mauryan Emperor Ashoka (273–235 BCE) was discovered near Srinivaspuri. Remains of several major cities can be found in Delhi. The first of these were in the southern part of present-day Delhi. King Anang Pal of the Tomara dynasty founded the city of Lal Kot in 736 CE. Prithviraj Chauhan conquered Lal Kot in 1178 and renamed it Qila Rai Pithora.

Late Medieval Period

The king Prithviraj Chauhan was defeated in 1192 by Muhammad Ghori in the second battle of Tarain, an invader from Afghanistan, who made a concerted effort to conquer northern India. By 1200, native Hindu resistance had begun to crumble, and the Muslim invaders were victorious. The newfound dominance of foreign Turkic Muslim dynasties in north India would last for the next five centuries. The slave general of Ghori, Qutb-ud-din Aibak, was given the responsibility of governing the conquered territories of India until Ghori returned to his capital, Ghor. When Ghori died without an heir in 1206 CE, his territories fractured, with various generals claiming sovereignty over different areas. Qutb-ud-din assumed control of Ghori's Indian possessions, and laid the foundation of the Delhi Sultanate and the Mamluk dynasty. He began construction of the Qutb Minar and Quwwat-al-Islam (Might of Islam) mosque, the earliest extant mosque in India. It was his successor, Iltutmish (1211–1236), who consolidated the Turkic conquest of northern India. Razia Sultan, daughter of Iltutmish, succeeded him as the Sultan of Delhi. She was the first and only woman to rule over Delhi prior to the British Raj. For the next three hundred years, Delhi was ruled by a succession of Turkic and an Afghan, Lodi dynasty. They built several forts and townships that are part of the seven cities of Delhi. Delhi was a major centre of Sufism during this period. The Mamluk Sultanate (Delhi) was overthrown in 1290 by Jalal ud din Firuz Khalji (1290–1320). Under the second Khalji ruler, Ala-ud-din Khalji, the Delhi sultanate extended its control south of the Narmada River in the Deccan. The Delhi sultanate reached its greatest extent during the reign of Muhammad bin Tughluq (1325–1351). In an attempt to bring the whole of the Deccan under control, he moved his capital to Daulatabad, Maharashtra in central India. However, by moving away from Delhi he lost control of the north and was forced to return to Delhi to restore order. The southern provinces then broke away. In the years following the reign of Firoz Shah Tughlaq (1351–1388), the Delhi Sultanate rapidly began to lose its hold over its northern provinces. Delhi was captured and sacked by Timur in 1398, who massacred 100,000 captives. Delhi's decline continued under the Sayyid dynasty (1414–1451), until the sultanate was reduced to Delhi and its hinterland. Under the Afghan Lodi dynasty (1451–1526), the Delhi sultanate recovered control of the Punjab and the Gangetic plain to once again achieve domination over Northern India. However, the recovery was short-lived and the sultanate was destroyed in 1526 by Babur, founder of the Mughal dynasty.


Early Modern Period

Babur was a descendant of Genghis Khan and Timur, from the Fergana Valley in modern-day Uzbekistan. In 1526, he invaded India, defeated the last Lodhi sultan in the First Battle of Panipat and founded the Mughal Empire that ruled from Delhi and Agra. The Mughal dynasty ruled Delhi for more than three centuries, with a sixteen-year hiatus during the reigns of Sher Shah Suri and Hemu from 1540 to 1556. In 1553, the Hindu king Hemu acceded to the throne of Delhi by defeating the forces of Mughal Emperor Humayun at Agra and Delhi. However, the Mughals re-established their rule after Akbar's army defeated Hemu during the Second Battle of Panipat in 1556.''Akbar the Great'', Srivastva, A.L. Vol. 1, pp. 24–26Himu-a forgotten Hindu Hero," Bhartiya Vidya Bhawan, p100Kar, L. Colonel H.C. ''Military History of India'' Calcutta 1980, p. 283 Shah Jahan built the seventh city of Delhi that bears his name ''Shahjahanabad'', which served as the capital of the Mughal Empire from 1638 and is today known as the ''Old City'' or ''Old Delhi''. Peshwa First_Battle_of_Delhi,_1737..html" style="text-decoration: none;"class="mw-redirect" title="Battle of Delhi (1737)">First Battle of Delhi, 1737.">alt=|thumb After the death of Aurangzeb in 1707, the Mughal Empire's influence declined rapidly as the Hindu Maratha Empire from Deccan Plateau rose to prominence. In 1737, Maratha forces led by Baji Rao I sacked Delhi following their victory against the Mughals in the First Battle of Delhi. In 1739, the Mughal Empire lost the huge Battle of Karnal in less than three hours against the numerically outnumbered but militarily superior Persian army led by Nader Shah of Persia. After his invasion, he completely sacked and looted Delhi, carrying away immense wealth including the Peacock Throne, the Daria-i-Noor, and Koh-i-Noor. The Mughals, severely further weakened, could never overcome this crushing defeat and humiliation which also left the way open for more invaders to come, including eventually the British. Nader eventually agreed to leave the city and India after forcing the Mughal emperor Muhammad Shah I to beg him for mercy and granting him the keys of the city and the royal treasury. A treaty signed in 1752 made Marathas the protectors of the Mughal throne in Delhi. In 1757, the Afghan ruler, Ahmad Shah Durrani, sacked Delhi. He returned to Afghanistan leaving a Mughal ruler named Alamgir II in nominal control. The Marathas again occupied Delhi in 1758, and were in control until their defeat in 1761 at the Third Battle of Panipat when the city was captured again by Ahmad Shah Durrani. However, in 1771, the Marathas established a protectorate over Delhi when the Maratha ruler, Mahadji Shinde, recaptured Delhi and the Mughal Emperor Shah Alam II was installed as a client of the Maratha Confederacy in 1772. In 1783, Sikhs under Baghel Singh captured Delhi and Red Fort but due to the treaty signed, Sikhs withdrew from Red Fort and agreed to restore Shah Alam II as the emperor.


Colonial Period

In 1803, during the Second Anglo-Maratha War, the forces of British East India Company defeated the Maratha forces in the Battle of Delhi. During the Indian Rebellion of 1857, Delhi fell to the forces of East India Company after a bloody fight known as the Siege of Delhi. The city came under the direct control of the British Government in 1858. It was made a district province of the Punjab. In 1911, it was announced that the capital of British-held territories in India was to be transferred from Calcutta to Delhi. The name "New Delhi" was given in 1927, and the new capital was inaugurated on 13 February 1931. New Delhi, also known as ''Lutyens' Delhi'', was officially declared as the capital of the Union of India after the country gained independence on 15 August 1947. During the partition of India, thousands of Hindu and Sikh refugees, mainly from West Punjab fled to Delhi, while many Muslim residents of the city migrated to Pakistan. Migration to Delhi from the rest of India continues (), contributing more to the rise of Delhi's population than the birth rate, which is declining.


Post-Independence

The States Reorganisation Act, 1956 created the Union Territory of Delhi from its predecessor, the ''Chief Commissioner's Province of Delhi''. The Constitution (Sixty-ninth Amendment) Act, 1991 declared the Union Territory of Delhi to be formally known as the National Capital Territory of Delhi. The Act gave Delhi its own legislative assembly along Civil lines, though with limited powers. In 2001, the Parliament of India building in New Delhi was attacked by armed militants, killing six security personnel. India suspected Pakistan-based militant groups were behind the attack, which caused a major diplomatic crisis between the two countries. There were further terrorist attacks in Delhi in 2005 and 2008, resulting in a total of 103 deaths.


Ecology

Delhi is located in Northern India, at . The city is bordered on its northern, western, and southern sides by the state of Haryana and to the east by that of Uttar Pradesh (UP). Two prominent features of the geography of Delhi are the Yamuna flood plains and the Delhi ridge. The Yamuna River was the historical boundary between Punjab and UP, and its flood plains provide fertile alluvial soil suitable for agriculture but are prone to recurrent floods. The Yamuna, a sacred river in Hinduism, is the only major river flowing through Delhi. The Hindon River separates Ghaziabad from the eastern part of Delhi. The Delhi ridge originates from the Aravalli Range in the south and encircles the west, northeast, and northwest parts of the city. It reaches a height of and is a dominant feature of the region. In addition to the wetlands formed by the Yamuna river, Delhi continues to retain over 500 ponds (wetlands < 5 ha), that in turn support considerable number of bird species. The National Capital Territory of Delhi covers an area of , of which is designated rural, and urban therefore making it the largest city in terms of area in the country. It has a length of and a width of . Delhi is included in India's seismic zone-IV, indicating its vulnerability to major earthquakes.


Climate

Delhi features a dry-winter humid subtropical climate (Köppen ''Cwa'') bordering a hot semi-arid climate (Köppen ''BSh''). The warm season lasts from 21 March to 15 June with an average daily high temperature above . The hottest day of the year is 22 May, with an average high of and low of . The cold season lasts from 26 November to 9 February with an average daily high temperature below . The coldest day of the year is 4 January, with an average low of and high of . In early March, the wind direction changes from north-westerly to south-westerly. From April to October the weather is hot. The monsoon arrives at the end of June, along with an increase in humidity. The brief, mild winter starts in late November, peaks in January and heavy fog often occurs. Temperatures in Delhi usually range from , with the lowest and highest temperatures ever recorded being , respectively. The annual mean temperature is ; monthly mean temperatures range from . The highest temperature recorded in July was in 1931. The average annual rainfall is approximately , most of which falls during the monsoon in July and August. The average date of the advent of monsoon winds in Delhi is 29 June.


Air pollution

According to the World Health Organization (WHO) Delhi was the most polluted city in the world in 2014. In 2016 WHO downgraded Delhi to eleventh-worst in the urban air quality database. According to one estimate, air pollution causes the death of about 10,500 people in Delhi every year. Air quality index of Delhi is generally moderate (101–200) level between January to September, and then it drastically deteriorates to Very Poor (301–400), Severe (401–500) or Hazardous (500+) levels in three months between October to December, due to various factors including stubble burning, fire crackers burning during Diwali and cold weather. During 2013–14, peak levels of fine particulate matter (PM) in Delhi increased by about 44%, primarily due to high vehicular and industrial emissions, construction work and crop burning in adjoining states. It has the highest level of the airborne particulate matter, PM2.5 considered most harmful to health, with 153 micrograms. Rising air pollution level has significantly increased lung-related ailments (especially asthma and lung cancer) among Delhi's children and women. The dense smog and haze in Delhi during winter results in major air and rail traffic disruptions every year. According to Indian meteorologists, the average maximum temperature in Delhi during winters has declined notably since 1998 due to rising air pollution. India's Ministry of Earth Sciences published a research paper in October 2018 attributing almost 41% of PM2.5 air pollution in Delhi to vehicular emissions, 21.5% to dust/fire and 18% to industries. The director of Centre for Science and Environment (CSE) alleged that the Society of Indian Automobile Manufacturers (SIAM) is lobbying "against the report" because it is "inconvenient" to the automobile industry. Environmentalists have also criticised the Delhi government for not doing enough to curb air pollution and to inform people about air quality issues. In 2014, an environmental panel appealed to India's Supreme Court to impose a 30% cess on diesel cars, but till date no action has been taken to penalise the automobile industry. Most of Delhi's residents are unaware of alarming levels of air pollution in the city and the health risks associated with it; however, , awareness, particularly among the foreign diplomatic community and high-income Indians, was noticeably increasing. Since the mid-1990s, Delhi has undertaken some measures to curb air pollution—Delhi has the third-highest quantity of trees among Indian cities and the Delhi Transport Corporation operates the world's largest fleet of environmentally friendly compressed natural gas (CNG) buses. In 1996, the CSE started a public interest litigation in the Supreme Court of India that ordered the conversion of Delhi's fleet of buses and taxis to run on CNG and banned the use of leaded petrol in 1998. In 2003, Delhi won the United States Department of Energy's first 'Clean Cities International Partner of the Year' award for its "bold efforts to curb air pollution and support alternative fuel initiatives". The Delhi Metro has also been credited for significantly reducing air pollutants in the city. However, according to several authors, most of these gains have been lost, especially due to stubble burning, a rise in the market share of diesel cars and a considerable decline in bus ridership. According to CSE and System of Air Quality Weather Forecasting and Research (SAFAR), burning of agricultural waste in nearby Punjab, Haryana and Uttar Pradesh regions results in severe intensification of smog over Delhi. The Circles of Sustainability assessment of Delhi gives a marginally more favourable impression of the ecological sustainability of the city only because it is based on a more comprehensive series of measures than only air pollution. Part of the reason that the city remains assessed at basic sustainability is because of the low resource-use and carbon emissions of its poorer neighbourhoods. On 3 January 2020, Delhi got its first smog tower to tackle air pollution.


Civic administration

Currently, the National Capital Territory of Delhi is made up of one division, 11 districts, 33 subdivisions, 59 census towns, and 300 villages. Local civic administration has, since the trifurcation of the former Municipal Corporation of Delhi (MCD) in January 2012, been in the hands of five bodies: *the East Delhi Municipal Corporation; *the North Delhi Municipal Corporation; *the South Delhi Municipal Corporation; *the New Delhi Municipal Council; and *the Delhi Cantonment Board. It was in July 2012, shortly after the MCD trifurcation, that the Government of Delhi increased the number of districts in the capital territory from nine to eleven. In terms of good governance and best administrative practices, Delhi was ranked fifth out of 21 Indian cities in 2014. It scored 3.6 out of 10 compared to the national average of 3.3. Delhi is home to the Supreme Court of India and the regional Delhi High Court. A Small Causes Court deals with civil cases, while a Magistrates' Court and the Sessions Court handle criminal cases in the city. For policing purposes Delhi is divided into eleven police districts which are further subdivided into 95 local police station zones.


Government and politics

As a first-level administrative division, the National Capital Territory of Delhi has its own Legislative Assembly, Lieutenant Governor, the council of ministers, and Chief Minister. Members of the legislative assembly are directly elected from territorial constituencies in the NCT. The legislative assembly was abolished in 1956, after which direct federal control was implemented until it was re-established in 1993. The Municipal corporation handles civic administration for the city as part of the Panchayati Raj Act. The Government of India and the Government of National Capital Territory of Delhi jointly administer New Delhi, where both bodies are located. The Parliament of India, the Rashtrapati Bhavan (Presidential Palace), Cabinet Secretariat, and the Supreme Court of India are located in the municipal district of New Delhi. There are 70 assembly constituencies and seven Lok Sabha (Indian parliament's lower house) constituencies in Delhi. The Indian National Congress (Congress) formed all the governments in Delhi until the 1990s, when the Bharatiya Janata Party (BJP), led by Madan Lal Khurana, came to power. In 1998, the Congress returned to power under the leadership of Sheila Dikshit, who was subsequently re-elected for 3 consecutive terms. But in 2013, the Congress was ousted from power by the newly formed Aam Aadmi Party (AAP) led by Arvind Kejriwal forming the government with outside support from the Congress. However, that government was short-lived, collapsing only after 49 days. Delhi was then under President's rule until February 2015. On 10 February 2015, the Aam Aadmi Party returned to power after a landslide victory, winning 67 out of the 70 seats in the Delhi Legislative Assembly. Since 2011 Delhi has had three municipal corporations: # SDMC having jurisdiction over South and West Delhi areas including Mahipalpur, Rajouri Garden, Janakpuri, Hari Nagar, Tilak Nagar, Dwarka, Jungpura, Greater Kailash, R K Puram, Malvya Nagar, Kalkaji, Ambedkar Nagar and Badarpur. # NDMC has jurisdiction over areas such as Badli, Rithala, Bawana, Kirari, Mangolpuri, Tri Nagar, Model Town, Sadar Bazar, Chandni Chowk, Matia Mahal, Karol Bagh, Moti Nagar # EDMC has jurisdiction over areas such as Patparganj, Kondli, Laxmi Nagar, Seemapuri, Gonda, Karawal Nagar, Babarpur and Shahadra In 2017 the BJP emerged the victors in elections to all three corporations.


Economy

Delhi is the largest commercial center in northern India. recent estimates of the economy of the Delhi urban area have ranged from $167 to $370 billion (PPP metro GDP) ranking it either the most or second-most productive metro area of India. * * * The nominal GSDP of the NCT of Delhi for 2016–17 was estimated at , 13% higher than in 2015–16. As per the Economic survey of Delhi (2005–2006), the tertiary sector contributes 70.95% of Delhi's gross SDP followed by secondary and primary sectors with 25.20% and 3.85% contributions, respectively. Delhi's workforce constitutes 32.82% of the population, and increased by 52.52% between 1991 and 2001. Delhi's unemployment rate decreased from 12.57% in 1999–2000 to 4.63% in 2003. In December 2004, 636,000 people were registered with various employment exchange programmes in Delhi. In 2001 the total workforce in national and state governments and the quasi-government sector was 620,000, and the private sector employed 219,000. Key service industries are information technology, telecommunications, hotels, banking, media and tourism. Construction, power, health and community services and real estate are also important to the city's economy. Delhi has one of India's largest and fastest growing retail industries. Manufacturing also grew considerably as consumer goods companies established manufacturing units and headquarters in the city. Delhi's large consumer market and the availability of skilled labour has also attracted foreign investment. In 2001, the manufacturing sector employed 1,440,000 workers and the city had 129,000 industrial units.


Utility services

Delhi's municipal water supply is managed by the Delhi Jal Board (DJB). , it supplied 650 million gallons per day (MGD), whereas the estimated consumption requirement is 963 MGD. The shortfall is met by private and public tube wells and hand pumps. At 240 MGD, the Bhakra storage is DJB's largest water source, followed by the Yamuna and Ganges rivers. Delhi's groundwater level is falling and its population density is increasing, so residents often encounter acute water shortage. Research on Delhi suggests that up to half of the city's water use is unofficial groundwater.
In Delhi, daily domestic solid waste production is 8000 tonnes which is dumped at three landfill locations by MCD. The daily domestic waste water production is 470 MGD and industrial waste water is 70 MGD. A large portion of the sewage flows untreated into the Yamuna river. The city's electricity consumption is about 1,265 kWh per capita but the actual demand is higher. In Delhi power distribution is managed by Tata Power Distribution and BSES Yamuna & Rajdhani since 2002. The Delhi Fire Service runs 43 fire stations that attend about 15,000 fire and rescue calls per year. The state-owned Mahanagar Telephone Nigam Limited (MTNL) and private enterprises such as Vodafone, Airtel, Idea Cellular, Reliance Infocomm, Aircel, Reliance Jio and Tata Docomo provide telephone and cell phone services to the city. Cellular coverage is available in GSM, CDMA, 3G and 4G.


Transport




Air

Indira Gandhi International Airport, situated to the south-west of Delhi, is the main gateway for the city's domestic and international civilian air traffic. In 2015–16, the airport handled more than 48 million passengers, making it the busiest airport in India and South Asia. Terminal 3, which cost to construct between 2007 and 2010, handles an additional 37 million passengers annually. In 2010, IGIA was conferred the 4th best airport award in the world in the 15–25 million category, by Airports Council International. The airport was rated as the ''Best airport in the world'' in the 25–40 million passengers category in 2015, by Airports Council International. Delhi Airport was awarded ''The Best Airport in Central Asia'' and ''Best Airport Staff in Central Asia'' at the Skytrax World Airport Awards 2015. The ''Delhi Flying Club'', established in 1928 with two de Havilland Moth aircraft named ''Delhi'' and ''Roshanara'', was based at Safdarjung Airport which started operations in 1929, when it was the Delhi's only airport and the second in India. The airport functioned until 2001; however, in January 2002 the government closed the airport for flying activities because of security concerns following the New York attacks in September 2001. Since then, the club only carries out aircraft maintenance courses and is used for helicopter rides to Indira Gandhi International Airport for VIP including the president and the prime minister. Hindon Domestic Airport in Ghaziabad was inaugurated by Prime Minister Narendra Modi as the second airport for the Delhi-NCR Region on 8 March 2019. A second international airport open for commercial flights has been suggested either by expansion of Meerut Airport or construction of a new airport in Greater Noida. The Taj International Airport project in Jewar has been approved by the Uttar Pradesh government.


Road

Delhi has the highest road density of 2103 km/100 km² in India. It is connected to other parts of India by five National Highways: NH 1, NH 2, NH 8, NH 10 and NH 24. The Delhi–Mumbai and Delhi–Kolkata prongs of the Golden Quadrilateral start from the city. The city's road network is maintained by MCD, NDMC, Delhi Cantonment Board, Public Works Department (PWD) and Delhi Development Authority. Buses are the most popular means of road transport catering to about 60% of Delhi's total demand. Delhi has one of India's largest bus transport systems. In 1998, the Supreme Court of India ruled that all public transport vehicles in Delhi must be fuelled by compressed natural gas (CNG) to tackle increasing vehicular pollution. The state-owned Delhi Transport Corporation (DTC) is a major bus service provider which operates the world's largest fleet of CNG-fuelled buses. In addition, cluster scheme buses are operated by Delhi Integrated Multi-Modal Transit System (DIMTS) with the participation of private concessionaires and DTC. In December 2017, the DTC and cluster buses carried over 4.19 million passengers per day. Kashmiri Gate ISBT, Anand Vihar ISBT and Sarai Kale Khan ISBT are the main bus terminals for outstation buses plying to neighbouring states. Delhi's rapid rate of economic development and population growth has resulted in an increasing demand for transport, creating excessive pressure on the city's transport infrastructure. To meet the transport demand, the State and Union government constructed a mass rapid transit system, including the Delhi Metro. Delhi Bus Rapid Transit System runs between Ambedkar Nagar and Delhi Gate. Personal vehicles especially cars also form a major chunk of vehicles plying on Delhi roads. , private vehicles account for 30% of the total demand for transport. Delhi has the highest number of registered cars compared to any other metropolitan city in India. Taxis, auto rickshaws, and cycle rickshaws also ply on Delhi roads in large numbers. , the number of vehicles in the metropolitan region, Delhi NCR, was 11.2 million (11.2 million). In 2008, there were 85 cars in Delhi for every 1,000 of its residents. In 2017, the number of vehicles in Delhi city alone crossed the ten million mark with the transport department of Delhi Government putting the total number of registered vehicles at 10,567,712 until 25 May of the year. Important Roads in Delhi Some roads and expressways serve as important pillars of Delhi's road infrastructure: * The Inner Ring Road is one of the most important "state highways" in Delhi.
