Answer - Road transport is a transportation of goods and passenger for short distances. It offers door to door services.
The problems of road transport in mountainous, desert and flood prone regions are different.
In mountainous region steep slope and unlevelled patterns are found which create obstacles in construction of roads. High amount of costs is required for maintenance and construction of roads.
In desert area excessive sand creates problems in construction of roads and in flood prone areas roads are damaged frequently.
(ii) What is a trans–continental railway?
Answer - Trans-continental railway run from one side of a continent to other side of the continent. It links two ends of continent. The main purpose for constructing trans-continental railway is economic development of different regions of a continent and political reasons. These networks also used for businesses. Industrialists could manage businesses on both coasts. Likely - Trans–Siberian Railway, Trans–Canadian Railways, The Australian Trans–Continental Railway and The Orient Express etc.

*The major regions of the world having a dense network of airways are U.S.A, Western Europe and Southeast Asia.
*U.S.A. alone has 60% of the airways of the world.
*Today, more than 250 commercial airlines offer regular services to different parts of world.
*The nodal points where air routes converge or radiate to all continents are New York, London, Paris, Amsterdam, Frankfurt Rome, Moscow, Karachi, New Delhi, Mumbai, Bangkok, Singapore, Tokyo and Chicago.
*U.S.A. developed largely post war International Civil Aviation.
*Some continents or countries lack air services. Likely - Africa, Asiatic part of Russia and South America etc.
