Summary
Class 12 Geography Chapter 7 (India: People and Economy) covers the major modes of transport in India — roads, railways, waterways, air, and pipelines — along with the development of personal and mass communication systems. It explains how these networks connect people, goods, and ideas across the country.
India has one of the largest road networks in the world at about 62.16 lakh km, carrying 85% of passenger and 70% of freight traffic. National Highways span 1,36,440 km (2020) and carry 40% of road traffic despite being only 2% of total road length. Indian Railways, introduced in 1853, now covers 67,956 km across 17 zones. India has 14,500 km of navigable waterways, while ocean routes handle 95% of foreign trade by volume. GAIL's HVJ pipeline (1,700 km) and OIL's Naharkatiya-Barauni pipeline (1,157 km) are key oil and gas arteries. Communication systems include personal (internet, e-mail) and mass media (radio since 1923, TV since 1959, satellite via INSAT from 1983).
