3.2. Transportation

The global economy functions through trade and commerce, and transportation service sector is the most essential aid. It not only supports the supply chain through timely movement of raw materials and resources, but also enables eventual distribution of finished goods, in turn assuring economic competitiveness and growth. It is also the mode of travel for people for employment and education opportunities, healthcare, leisure, or social networking, etc. But while this was greatly hampered in the pandemic era, with millions with home bound.

Transportation is crucial for the economy because it facilitates trade by moving raw materials to manufacturers and finished products to consumers. Without transportation, businesses couldn't deliver goods efficiently, which would slow down economic activity. During the pandemic, many people were forced to stay at home which disrupted this flow, highlighting how vital transportation is in everyday life and the economy.

Think of a restaurant that needs fresh ingredients daily to prepare meals. If the delivery trucks (transportation) are unable to bring in fresh vegetables and meats on time, the restaurant can't serve its dishes, leading to lost sales and unhappy customers. This shows how transportation directly impacts business operations and economic growth.

Land transport can be broadly categorised into roads, railways and metros; a ‘way’ for travel. The word ‘way’ as per Britannica, stems from the Latin ‘veho’ which means, 'I carry', derived from the Sanskrit word, ‘vah’ meaning to 'carry, go or move'.

Land transport consists of various means like roads, railways, and metros that facilitate the movement of people and goods. The term 'way' comes from ancient languages indicating its foundational role in transport. Each mode of land transport has specific characteristics and serves distinct purposes in society, making it essential for connectivity and economic activities.

Imagine a busy city where people use different modes of transport: cars travel on roads, trains run on railways, and metros provide quick access across urban areas. Each type of transport plays a unique role in keeping the city moving, similar to how different parts of a watch work together to tell time.

The earliest records of animal trodden paths used by man have been dated back to 6000 BCE, with evidence on first constructed road dating 4000BCE at Ur, present day Iran. Oldest existing paved road, made of layers of sandstone bound by clay-gypsum mortar with two rows of basalt slabs in the centre for use by foot, while the dipping edges were for animals, was built by the Minoans on the island of Crete.

Roads have been critical for human development since ancient times. The first paths allowed early humans to travel and trade, evolving into paved roads that could support heavier loads and more traffic. Roads enabled societies to connect, trade, and grow economically. Ancient civilizations like the Romans and Minoans designed roads that facilitated long-distance travel and commerce.

Consider a modern highway that allows for fast travel between cities, making it easier for businesses to reach their markets and for families to visit loved ones. Just like in ancient times, roads are foundational to our lives today.

In earlier chapters, we have discussed the oncoming of railways. The role civil engineer is pivotal for railway transport infrastructure, and encompasses surveying for a new line, construction and maintenance of the line, ensuring longevity, safety and reliability of the structure.

Railways have transformed transportation by enabling efficient movement of goods and passengers over long distances. Civil engineers are essential in planning and constructing railway lines, ensuring they are safe and durable. They survey land, design tracks, and manage construction, making rail networks a backbone of transportation infrastructure.

Think of the role of an architect in building a skyscraper. Just as architects ensure that buildings are structurally sound and suitable for use, civil engineers work on railways to create safe and reliable transport options for everyone who relies on trains for travel or transporting goods.

Today, the Indian Railways is Asia’s largest network and among the world’s largest. It is about 108,706 track Kms and runs around 11000 trains daily, off which 7000 are passenger trains carrying around 13 million passengers every day.

Modern transportation infrastructure, like India's railways, represents significant engineering achievement. With vast networks and high traffic volume, railways must be managed efficiently to maintain service quality. The Indian Railways plays a vital role in connecting people and facilitating commerce, showcasing how effective transportation can positively impact millions of lives.

Consider how a subway system in a big city allows countless commuters to travel swiftly to work every day. Similarly, India's extensive railway network connects remote areas to urban centers, ensuring that people can travel easily for work while also enabling visitors to explore the country.

Civil engineering plays a crucial role in the design of water transportation and construction of ports and harbours. Ports are locations where ships and vessels can dock and allow movement of people and goods and are either on coasts or shores, while harbours are constructed for the safe keeping of the vessels.

Water transport, including seaports and harbors, is essential for international trade. Civil engineers design these structures to ensure they can accommodate large vessels and facilitate safe loading and unloading of goods. Ports serve as gateways for commerce and require careful planning to maximize efficiency and safety in operations.

Think of a large airport where planes land and take off. Just like airports facilitate air travel and cargo transport, seaports allow ships to load and unload products from around the world, making them vital to a country's economy.
