Means of transport and communication are complementary to each other: 1. Science and technology have radically improved communication between distant areas facilitating transport between both. For example, a person in Gujarat can know the transport facilities in Odisha through communication. 2. Transport has contributed a lot to improved communication. For example, packages from a country can reach any corner of the world because of improved transportation. 3. World-wide trade relations and policy making has been enabled only because of efficient transport as well as communication.
