National Highways
- NH referred to roads which are constructed and maintained by central government.
- National Highways are meant for inter-state transport and movement of defence men and material in strategic areas.
- In 2008-09, total length of National Highways was 70934 km which was 19700 km in 1951.
- These highways connect the state capitals, major cities, important ports, railways junctions, etc and carry’ about 40% of the road traffic despite they constitute only 1.67% of total road length.
- The National Highways Authority of India (NHAI – 1^95) is an autonomous body, under the Ministry of Surface Transport which is entrusted with the responsibility of development, maintenance, operation and for the improvement of the quality of national Highways.
National Highways Development Projects
- Golden Quadrilateral It is 5846 km long 4/6 lane, high density corridor. It was meant to connect India’s four big metro cities of Delhi-Mumbai- Chennai-Kolkata. It will deduct the time-distance and cost of movement among the mega cities of India. Its construction help ip reducing the time distance and cost of movement among mega cities considerably.
- North-South and East-West corridors The North-South corridor is a 4076 km long highway which is meant to connect Srinagar in Jammu and Kashmir with Kanyakumari in Tamil Nadu including Kochchi-Salem Spur. The East-West corridor is 3640 km long road which aims to connect Silchar in Assam with the port town of Porbandar in Gujarat.
Density of Roads
- The distribution of roads is not uniform in the country. Density of roads (length of roads per 100 sq km of area) is the method to compare the network of roads of one area to another area. The national average road density is 125.02 km (2008).
- The density of roads is influenced by nature of terrains, and level of economic development. As most of the Northern states and major Southern states have high density of roads (e.g. Uttar Pradesh has highest road density of 532.27 km), whereas Himalayan region, North-Eastern region, Madhya Pradesh and Rajasthan have low density of roads (e.g. Jammu and Kashmir has lowest road density of 10.04 km).
- Quality of roads, besides density, is also better in plains as compared to high altitude areas, rainy and forested regions.
Rail Transport
- India has one of the longest railway network in the world. On one hand, it facilitates the movement of freight and passengers and on the other hand, it contributes to the growth of economy. Mahatama Gandhi said, the Indian railways, “brought people of diverse cultures together to contribute to India’s freedom struggle”
- In 1853, the first Indian railway was started from Bombay to Thane covering a distance of 34 km.
- Being the largest Government undertaking in India, Indian Railways network is 64460 km long (31th March, 2011).
- To reduce the pressure of this large size railway from a centralised railway management system, Indian Railway system has been divided into seventeen zones.
These are as follows:
Railway Zone Headquarters
1. | Central | Mumbai CST |
2. | Eastern | Kolkata |
3. | East Central | Hojipur |
4. | East Coast | Bhubaneswar |
5. | Northern | New Delhi |
6. | North-Central | Allahabad |
7. | North-Eastern | Gorakhpur |
8. | North East Frontier | Maligaon (Guwahati) |
9. | North-Western | Jaipur |
10. | Southern | Chennai |
11. | South Central | Secunderabad |
12. | South-Eastern | Kolkata |
13. | South East Central | Bilaspur |
14. | South-Western | Hubli |
15. | Western | Mumbai (Church Gate) |
16. | West Central | Jabalpur |
17. | Metro | Kolkata |
- Broad Gauge In broad gauge, the distance between rails is 1.676 metre. The total length of broad gauge lines is 55188 km in 2011.
- Metre Gauge In metre gauge, the distance between the rails is 1 metre. The total length of metre gauge is 6809 km in 2011.
- Narrow Gauge In narrow gauge, the distance between the rails is 0.762 metres or 0.610 metres. The total length of narrow gauge line is 2463 km in 2011. This category of railway lines is mostly found in the hilly areas.
Indian Railways has taken major steps to improve the performance of this means of transport like:
- To convert the metre and narrow gauges to broad gauge.
- Replacement of steam engine by diesel and electric engines which may help in keeping the environment clean.
- Introduction of metro rail in Kolkata and Delhi, etc.
Development of railways in India was started by the Britishers and after the independence, scenario has been changed by extending railway routes to other areas. Konkan railways along the western coast which provide a direct line between Mumbai and Mangalore was a significant development in this regard.
Konkan Railway is one of the important achievements of Indian Railways which was constructed in 1998. It is a 760 km long rail route which connects Roha in Maharashtra to Mangalore in Karnataka. It is considered an engineering marvel. Railway is still the most important means of transport for the masses. In the hill states, North-Eastern states, central part of India and Rajasthan, railway network is relatively less dense.
- Inland Waterways
- Oceanic Waterways
- Tough competition from road and railway transport.
- Diversion of river water for irrigation purposes made them non-navigable in large parts of their courses.
The Inland Waterways Authority which was setup in 1986 is responsible for the development, maintenance and regulation of national waterways in the country. Currently, there are three inland waterways which are considered as national waterways by the authority. Description of these waterways are as follows:
Oceanic RoutesTen other inland waterways have been identified by inland waterways authority. The backwaters (Kadal) of Kerala has special significance which not only provides transport but also attract tourists here. The famous Nehru Trophy Boat Race (Vallamkali) is also held in the backwaters.
- These play an important role in the transport sector of India’s economy.
- India’s vast coastline of about 7,517 km (including islands) easily facilitates this type of transport. There are twelve major and 185 minor ports which provide infrastructural support to these routes.
- About 95% of India’s foreign trade by volume and 70% by value moves through ocean routes.
- These routes give international trade service as well as provide transportation between the islands and the rest of the country.
The Airport Authority of India is responsible for providing safe, efficient air traffic and aeronautical communication services in the Indian Air space. Now it manages 126 airports including 11 international, 86 domestic and 29 civil enclaves at defence air fields. There are two corporations, Air India and Indian Airlines which manage air transport in India. Both corporations were nationalised in 1953. Now many private companies have also started passenger services.
History of Indian Airlines
- 1911-Air transport in India was launched between Allahabad and Naini.
- 947-Air transport was provided by four major companies namely Indian National Airways, Tata Sons Limited, Air Services of India and Deccan Airways.
- 1951-Four more companies joined the services i.e. Bharat Airways, Himalayan Aviation Limited, Airways India and Kalinga Airlines.
- 1953-Air transport was nationalised and two corporations, Air India international and Indian Airlines were formed. Now, Indian Airlines is known as Indian.
- Pawan Hans is the major organisation in India which provides helicopter services in hilly areas, for tourism in North-Eastern sector and mainly to petroleum sector and tourism.
Its one of the major achievement is the construction of Asia’s first cross country pipeline. This pipeline covers a distance of 1157 km from Naharkatiya oil field in Assam to Barauni refinery in Bihar. In 1966, this pipeline was further extended to Kanpur, Uttar Pradesh.
In Western region of India, OIL also constructed extensive network of pipelines – Ankleshwar-Koyali, Mumbai High-Koyal and Hazira-Vijaipur-Jagdishpur (HVJ) pipelines. Recently, a pipeline is also constructed from Salaya (Gujarat) to Mathura (Uttar Pradesh). It is 1256 km long pipeline which transport crude oil from Gujarat to Punjab (Jalandhar) via Mathura. Construction of a 660 km long pipeline from Numaligarh to Siliguri is also in progress.
On the basis of scale and quality, the mode of communication can be divided into following categories:
Personal Communication System
- The most advanced and best means among all personal communication system is internet which is widely used in urban cities.
- E-mail is the main source through which a user can directly connect with others and can also get access to the world of knowledge and information.
- Use of internet is increasing for e-commerce and carrying out money transactions.
- The internet is like a huge control warehouse of data, with detailed information on various items.
- It is a cheaper mode of communication which provides an efficient access to information at a comparatively low cost.
- Letters, telephone, fax are also used for personal communication.
Mass Communication System Radio
- Radio broadcasting was started in 1923 by Radio Club of Bombay. Within short time, it gained immense popularity and became a part of every househod in India.
- After seeing its popularity, the government of India, in 1930 took the control of this mode of communication under Indian Broadcasting System.
- It was changed to All India Radio in 1936 and to Akashwani in 1957.
- It broadcasts various programmes related to information, education, entertainment and special news bulletins on special session of parliament and state legislature.
Television (TV)
- Television (TV) broadcasting has emerged as the most effective audio-visual medium for disseminating information and educating masses.
- First television broadcasting was started in National Capital in 1959. Till 1972, it was the only urban place where TV services were available.
- After 1972, several other centres became operational. In 1976, TV broadcasting services were separated by All India Radio and got a separate identity as Doordarshan (DD).
- Its revolutionary development began after the launch of INSAT-IA (National Television -D1) when Common National Programmes (CNP) were started for the entire network and its services were extended to the backward and remote rural areas.
Indian Remote Sensing Satellite System (IRS)
- The IRS satellite system started in India with the launch of IRS-IA in March 1988 from Vaikanour in Russia.
- India has also developed her indigenous launching vehicle PSLV (Polar Satellite Launch Vehicle).
- These remote sensing satellites collect data in several spectral band and transmit them to ground stations which is very useful in the management of natural resources and other various purposes.
- The National Remote Sensing Agency (NRSA) at Hyderabad is responsible for facilitating for acquisition of data and its processing.
