Transport

Controlled access through absence of multiple roads on an Expressway.

Reason — an Expressway is a controlled-access road with limited entry and exit points and no direct access from multiple connecting roads or intersections, unlike a highway.

Waterways

Explanation — National Waterway No. 1 that connects Haldia-Kolkata-Farakka-Munger-Patna-Varanasi-Allahabad can be used to transport this large consignment of silk fabric from Varanasi to Haldia port.

Both A and R are true and R is the correct explanation of A.

Explanation — Transportation enables the better utilisation of resources by connecting different regions and facilitating the movement of raw materials and finished goods. Therefore, it functions like the arteries and veins of the human body, ensuring the smooth flow of goods and economic activities.

Srinagar to Kanyakumari

Reason — The North-South Corridor, a part of the NS-EW Corridor project, consists of four/six lane expressways that connect Srinagar in the north to Kanyakumari in the south.

Porbandar and Silchar

Reason — The East-West Corridor, a part of the NS-EW Corridor project, consists of four/six lane expressways that connect Porbandar in the west to Silchar in the east.

Jhansi

Reason — The North-South Corridor (Srinagar–Kanyakumari) and the East-West Corridor (Porbandar–Silchar) intersect at Jhansi.

Both A and R are true and R is the correct explanation of A.

Explanation — Industrialisation increases traffic on National Highways, and the NHAI develops and maintains these highways to support this growing demand. Thus, NHAI's role supports the increased traffic due to industrial growth.

Roadways

Reason — Roads offer door to door service and also help farmers to move their perishable products quickly to the markets.

Both A and R are true but R does not explain A.

Explanation — While both Assertion (A) and Reason (R) are true, Reason (R) does not explain Assertion (A) as Reason (R) is stating the consequence of high traffic, and not its cause.

Width of the track

Reason — Based on the width of the track, the Indian Railways are divided into three categories, namely Broad Gauge, Metre Gauge and Narrow Gauge.

Broad Gauge

Reason — The Broad Gauge covers almost all the main routes and handles the bulk of the goods traffic, and hence it is also called the India gauge.

Both A and R are true and R is the correct explanation of A.

Explanation — Indian Railways' huge size has put pressure on the centralised management system. Therefore, to ease this pressure, the railway system has been divided into 18 zones.

1 m

Reason — In a metre gauge, the distance between the rails is one metre.

Ease of crossing difficult terrain

Reason — The speed and ease with which aeroplanes can cross mountain barriers, sandy deserts, large expanses of water or forests make air transport indispensable.

Inland waterways

Reason — This navigable length made up of rivers and canals that can be used by mechanised flat bottom vessels refers to the inland waterways of India.

Both were constructed with the aim to reduce pressure on major ports.

Reason — Haldia Port was developed to reduce congestion at Kolkata Port, while Nhava Sheva (Jawaharlal Nehru Port) was developed to reduce pressure on Mumbai Port.

waterfalls.

Reason — The rivers of Peninsular India are marked by a number of waterfalls, which makes them unsuitable for use as inland waterways.

A is true but R is false.

Explanation — While Assertion (A) is true, Reason (R) is false as freight transportation by waterways is highly underutilised in India.

Cheap; environment friendly

Reason — Inland water transport is a cost-effective (cheap) and environment friendly mode of transport.

Ennore

Reason — Ennore is an artificial port, whereas Mumbai, Kochi, and Visakhapatnam are natural harbours.

The types of roads used in India are as follows-

Two major projects developed by NHAI are:

1. Golden Quadrilateral
2. North-South and East-West Corridors

Transport is the backbone of a country's economy because of the following reasons:

1. Transportation helps in the better utilisation of the resources of the backward areas by linking them with the more advanced areas.
2. It aids in the process of industrialisation and urbanisation.
3. It removes scarcity of goods during any crisis.
4. It helps in minimising the effects of natural disasters.
5. It brings in homogeneity and National integration in thought and culture through easy movement of people and bringing them in contact with each other.

Road transport in India is considered more useful than rail transport because of the following reasons-

1. Roads make every village and hamlet reachable.
2. Construction cost of roads is much lower than that of the railway line.
3. Roads can be constructed even in the areas of difficult terrain and where railway lines do not exist.
4. Roads offer door to door service and thereby, reduce the cost of loading and unloading.
5. The movement of goods is safer through road transport as the chances of pilferage are lesser than in the railways.
6. Road transport provides link between railway stations and ports and their hinterlands.

Expressways are highways planned for high-speed traffic, having few intersection, limited points of access or exit and a divider between lanes for traffic moving in opposite directions. They usually have six to eight lanes.

An example is Yamuna Expressway that connects Greater Noida with Agra.

Two advantages of railways are-

1. Railways transport raw materials to the production units and finished goods to the markets.
2. Railways help in reducing sufferings during natural calamities.

One disadvantage of railways is that rail transport lacks flexibility of routes. Train tracks cannot be laid in every region of the country like in the hilly areas and the remote forested areas.

Three problems being faced by the Indian Railways are-

1. Indian Railways have to play a double role of revenue earning as well as fulfilling the social obligations. This is because the Railways are seen as a commercial organisation on one hand and it is treated as a social organisation on the other hand.
2. Railway lines are difficult to construct in the hilly and mountainous parts of India.
3. Obsolete trains, tracks and equipment make railway unsafe.

The main roads which are constructed and maintained by the Central Government are known as National Highways. These are main highways running through the length and breadth of the country and are the backbone of road infrastructure.

National Highways in India are designated as NH followed by the State highway numbers.

The Golden Quadrilateral is the largest express highway project in India. It connects India's four largest metropolies: Delhi, Mumbai, Kolkata and Chennai and thus, forms a quadrilateral of sorts. Bengaluru, Pune, Ahmedabad and Surat are also served by this network.

Three economic benefits of the Golden Quadrilateral Project are-

1. This highway interconnects many major cities and ports. It provides an impetus to truck transport throughout India.
2. It enables the industrial growth of all small towns through which it passes.
3. It provides vast opportunities for transport of agricultural produce from hinterland to major cities and ports for export.

The role of roads in the economic development of the country can be understood from the following points-

1. Roads offer door to door service and thereby, reduce the cost of loading and unloading. Roads also help farmers to move their perishable products quickly to the markets.
2. National highways and expressways link various important cities and reduce the time of travel and distance between mega cities.
3. Construction cost of roads is much lower than that of the railway lines and roads connect the fields of raw material to industries and markets.

The significance of an efficient transport system is as follows-

1. Transportation helps in the better utilisation of the resources of the backward areas by linking them with the more advanced areas.
2. It aids in the process of industrialisation and urbanisation.
3. It removes the scarcity of goods during times of crisis.
4. It helps in minimising the effects of natural disasters.
5. It promotes national integration and homogeneity in thought and culture by facilitating the easy movement of people and bringing them into contact with one another.

The types of gauges of railways used in India are-

1. Broad gauge
2. Metre gauge
3. Narrow gauge

(i) Railways constitute the principal mode of transportation for freight and passengers. They bind the economic life of the country by carrying a huge variety of goods, such as mineral ores, fertilisers, petrochemicals, agricultural produce, iron and steel. Ports and major urban areas have their own freight lines. Thus, railways accelerate the development of industry and agriculture, thereby improving the economic conditions of the country.

Further, railways bind the cultural life of the country by bringing people together from the farthest corners of the country for business, sightseeing, pilgrimage, education, etc.

(ii) The north-eastern part of the country is marked by the presence of big rivers, dissected relief, dense forests, frequent floods, landslides and international frontiers. Since it is difficult to lay railway lines in hilly terrain and remote forested areas, railways are not common in North-East India.

(iii) North India is better suited for railways and roadways because it has level land with a gentle slope due to the Northern Plains. It is easier to construct roads and lay railway tracks on level land than in hilly or densely forested regions.

The Indian rail network is one of the largest and busiest networks in the world, transporting over 18 million passengers and more than 2 million tonnes of freight daily. It is the world's largest employer, with more than 1.4 million employees. The railways traverse the length and breadth of the country, covering 7,137 stations over a total route length of more than 66,030 kilometres.

The Airports Authority of India is looking after air transport in India.

Two of its functions are-

1. It provides aeronautical communication services in the country.
2. It is responsible for creating, upgrading, maintaining and managing civil aviation infrastructure.

Air India provides international service for both passengers and cargo. It is the 16th largest airline in Asia, serving 50 domestic destinations and 39 international routes and serving over 100 cities.

Two advantages of air transport in India are-

1. It is the fastest and comfortable mode of transport. It connects the far flung and remote areas of the country.
2. The speed and ease with which aeroplanes can cross mountain barriers, sandy deserts, large expanses of water or forests make the air transport indispensable.

One disadvantage of air transport in India is that it is costly.

Two advantages of helicopter services over aeroplane services are-

1. Helicopters can hover, take off and land vertically, so they do not require long runways.
2. They are useful in remote and inaccessible areas and are widely used for rescue operations, airlifting, flying ambulances, firefighting, tourism and VIP transport.

One disadvantage of helicopter services over aeroplane services is that, helicopter have a limited carrying capacity and are more expensive to operate, making them unsuitable for transporting large numbers of passengers or heavy cargo.

India has an extensive network of water ways because it has a long indented coastline. India also have a good network of inland waterways as it has numerous rivers, canals, backwaters and creeks. The river Ganga and Brahmaputra are perennial rivers and hence are also used for inland navigation.

Oceanic waterways constitute an important role in the transport sector of India's economy as ocean routes handle 95% of India's foreign trade by volume and about 70% by value. Besides international trade, these routes are also used for transportation between the islands and the rest of the country.

(i) The Ganga is navigable from its mouth up to Allahabad because:

1. It is a perennial river, fed by monsoon rains and melting snow from the Himalayas.
2. It has sufficient depth and a gentle gradient, making navigation possible.
3. Its wide channel allows inland water transport over a long distance.

(ii) The Peninsular rivers are not ideal for inland water transport because of the following reasons-

1. These rivers are seasonal as they are rain-fed.
2. These rivers are comparatively shorter than the rivers of northern India.
3. These rivers are marked by a number of waterfalls.

(iii) Mumbai is a natural harbour because it is sheltered by land and provides safe anchorage for ships. It is also a port because it has facilities for loading and unloading cargo, warehouses, docks and well-developed transport links.

(i) The factors upon which the growth of this means of transport depends on are:

1. Water availability and navigability
2. Infrastructure development
3. Government policies and Investment
4. Economic competitiveness with other transport modes.

(ii) The disadvantages of Inland waterways are given below:

1. These waterways must be free of barriers such as waterfalls and rapids, which makes the rivers of Peninsular India not ideal for navigation.
2. Navigation issues due to seasonal fluctuation of water, shallow depth, undulating river beds and their silting, and reduction of water level due to diversion for irrigation.
3. Inadequate infrastructure.
4. Slower transportation.
5. It depends on weather conditions.

The two prerequisites of waterways to be navigable are-

1. Regular flow of water
2. Appropriate depth in which the craft can sail easily.

(i) Inland waterways are more economical because they are the cheapest means of transport for carrying heavy and bulky goods over long distances. They also require less fuel and lower maintenance costs than road and rail transport.

(ii) A well-developed transport network is important for industrial progress because it connects different parts of the country and facilitates the movement of raw materials, fuel and machinery to the centres of production and finished goods to the markets. Thus, it promotes industrialisation and urbanisation.

(iii) Airways are quite useful during natural calamities because they help in airlifting people from affected areas and air-dropping food, medicines and other relief materials where other modes of transport cannot reach.

(i) Two points of difference between a port and a harbour are-

(ii) National Waterway No. 2 lies on Brahmaputra river and connects the North-East region with Kolkata and Haldia ports through Bangladesh and Sunderbans waterways.

The Government of India is constructing airports in towns, tourist destinations, and pilgrimage points due to the following reasons:

1. Enhanced Connectivity: Smaller towns and remote locations gain improved links to major cities and global air networks. This reduces travel time and connects previously isolated regions.

2. Economic Development and Regional Growth: Better air connectivity facilitates tourism, pilgrimage, and business travel, which in turn stimulates local economies. It helps spread economic growth beyond traditional urban centers.

3. Promotion of Tourism and Cultural Exchange: Airports at tourist and pilgrimage destinations make it easier for both domestic and international visitors to access these regions, thereby boosting tourism and cultural interaction.

The development of waterways promotes industries by providing a cheap and economical means of transporting heavy and bulky goods.

For example, National Waterway No. 1, which connects Allahabad–Varanasi–Patna–Munger–Farakka–Haldia, facilitates the transport of goods between industrial centres and ports. This supports trade and encourages industrial development..

(i) Four cities that are connected by the north-south corridor are

1. Delhi
2. Nagpur
3. Hyderabad
4. Bengaluru

(ii) Two reasons in support of NHAI's highway projects are as follows-

1. To handle increasing traffic on National Highways.
2. To reduce travel time and ensure smooth flow of goods and people.

The Yamuna Expressway helps give impetus to the sugar industry by improving connectivity between sugar-producing areas of western Uttar Pradesh and major markets like Delhi and Noida. This reduces transportation time and cost, ensuring quicker delivery of sugarcane to mills and processed sugar to markets, thereby boosting the efficiency and profitability of the sugar industry.

The issue of increasing vehicular pollution is indeed a significant concern in many cities of India. While it's important to address this problem, completely halting the construction of new roads, bridges, and tunnels may not be the most practical solution because of the following reasons:

1. Economic growth and development rely on well-connected infrastructure, making it necessary to construct new roads, bridges, and tunnels.
2. Effective traffic management measures like improved public transportation and congestion charges can alleviate pollution without halting infrastructure projects.
3. Implementing stricter environmental regulations and vehicle emission standards can reduce pollution levels without stopping infrastructure development.
4. Sustainable urban planning and design, such as pedestrian-friendly areas and dedicated cycling lanes, can promote alternative modes of transportation.
5. Incorporating green infrastructure elements alongside road networks can improve air quality and mitigate pollution. Balancing economic growth and environmental sustainability requires a comprehensive approach.

While it's essential to consider a balanced transportation approach, focusing more on the development of Metro rail in India can offer several advantages:

1. Efficient and sustainable — Metro rail systems consume less energy, produce fewer emissions, and can transport a large number of passengers at once.
2. Reduced congestion — Metro rail networks can lead to smoother traffic flow, reduced travel time, and improved overall efficiency of the transportation system.
3. Improved connectivity — Metro rail systems can enhance connectivity within cities and regions.
4. Safety and reliability — Metro rail networks are designed with safety measures, reducing the risk of accidents compared to road transport.
5. Space utilization — Metro rail systems require less physical space compared to road networks.
