Transport — Part 1: Importance, roadways and highway corridors: visual lesson, ICSE Class 10 Geography (H.C.G. Paper 2)

Lesson

The arteries of a nation

Part 1 — A tea packet from Assam, a car from Chennai and a sack of wheat from Punjab all reach your town by transport. India uses land transport (roads, railways, pipelines), water transport (inland, coastal, overseas) and air transport. In this part we study why transport matters and how India’s roads and highway corridors are organised.

In this lesson you will

Explain why an efficient transport network is essential for development
Explain the factors that affect road development in different terrains and list advantages and disadvantages of road transport
State the meaning and importance of expressways, National Highways, the NSEW Corridor and the Golden Quadrilateral

Table of the three modes of transport with types and uses
Mode	Main types	Typical use
Land	Roads, railways, pipelines	People and goods across the country
Water	Inland, coastal, overseas	Heavy, bulky goods
Air	Domestic and international	Fast travel, valuable goods

Why transport matters

An efficient transport network is essential for development. It carries raw materials to factories and finished goods to markets; lets farmers sell perishable crops in distant cities; widens trade, both inside the country and abroad through ports; creates jobs in transport itself; supports tourism; helps defence and disaster relief reach border and remote areas quickly; and promotes national integration by bringing people of different regions together.

Table of five roles of transport with examples
Role	Example
Raw materials to industry	Iron ore from Odisha to steel plants
Goods to market	Apples from Himachal to Delhi
Trade	Containers through ports
Relief and defence	Supplies to border and flood areas
Integration	People of all regions travel and meet

Concept

Modes working together

Modes complement one another. A consignment often moves by road from a farm or factory to a railway yard, by rail across the country, by road again to a port, and by ship overseas. Pipelines carry crude oil, gas and petroleum products. Each mode suits certain loads, distances and terrains — the skill is in combining them.
