Why do roadways have an edge over railways? Explain four reasons.
The length of road per 100 sq km of area is known as density of roads.
Advantages of roadways over railways are
(i) Construction cost of roads is much lower than railway lines.
(ii) Roads can be constructed easily in hilly terrains and undulating topography.
(iii) Roadways act as a feeder to other modes of transport, as they provide a link between railway stations, air and sea ports.
(iv) Road transport is economical in transportation of few persons and relatively smaller amount of goods over short distances.
Thus, it can be concluded that roadways still have an edge over railways in India.
