What encompasses various forms of transportation such as roads and railways?

Transport links refer to the various systems and infrastructures that facilitate the movement of people and goods from one location to another. This includes roads, railways, airports, and waterways, making it a broad term that captures all types of transportation modes. Roads and railways are integral parts of the transport link system, allowing for efficient connectivity between different areas. The concept suggests a network that not only includes physical pathways but also the relationship and interaction between different modes of transport.

Communication networks, while important, generally pertain to the transmission of information rather than the physical movement of people or goods. Road systems are more specific to the infrastructure for road transport, and transit routes typically refer to specific paths taken by public transportation. Thus, transport links is the most comprehensive choice that accurately reflects the inclusion of various types of transportation systems.
