UNDERSTANDING THE VALUE OF TRANSPORT INFRASTRUCTURE
• Intermodal freight facilities within the airport with connections to modes other
than road on its landside.
• Connections to other modes of transport provided within the airport for connection
to other modes of surface transport, including access to high speed rail services,
access to main line rail services, access to city metro and underground services,
access to express and inter urban coach services and access to local bus services.
Sea port
The Glossary of Transport Statistics defines a port as a place having facilities for
merchant ships to moor and to load or unload cargo or to disembark or embark
passengers to or from vessels, usually directly to a pier. The definition of a port includes
port land-side facilities such as storage and stacking areas, port cranes, port repair
facilities, navigation aids and services as well as hinterland links.
2.3 Critical data needs and availability of data
To invest efficiently in transport infrastructure, policy and decision makers need to have,
at minimum, key information on:
• Infrastructure inventory - the type, amount (i.e., stock), location, and condition of
transport infrastructure, categorized by mode;
• Use and performance - the effectiveness and efficiency of the transport
infrastructure in moving people and goods, as well as the undesirable
consequences (e.g., accidents);
• Factors affecting the performance of the transport infrastructure - such as the
aging of, and the increasing demand on, the infrastructure;
• Economic drivers - trends and developments that affect economic growth;
• Investment impacts and trades-off - the costs and impacts of competing
investment choices.
Unfortunately, the available information is often extremely limited.
This section identifies minimum data requirements to carry out the macroeconomic
analysis where the relationship between transport infrastructure investment and
economic development will be developed. The minimum data requirements include
investment flows by mode and by asset type as well as operation and maintenance
(routine and periodic) expenditure by mode and by asset type. Furthermore, there is a
need for breakdown of data by asset types. For example, productivity, determinants and
financing of roads are very different from that for rail (and rail track from rolling stock),
so there is a need to report and analyse different types of infrastructure assets
separately.
To estimate the productivity of, say, road infrastructure, one needs information not only
on the size and the use (traffic flow) of the road network (stock) but also on the marginal
productivity. This information is needed also in monetary terms to be able to: (1) add
them up (1 km of road can have very different values in different locations); and to (2)
account for its quality. As infrastructure reduces production and transaction costs, its
