The case studies reinforce the importance of major international gateway and corridor infrastructures to international trade and the economies of each country. International passenger and freight movements are highly concentrated along major trade corridors, distinguished by high-volume, efficient services. Major international ports, airports and key inland transport connections in each country handle the bulk of the traffic. Increases in demand can be expected along inland connections from gateways to the cities and industrial areas in their hinterlands, making each country’s international gateways and inland trade corridor infrastructures even more important to its national economy. World-class gateway, hub and inland infrastructure will be required in the future to attract the transport services required and to fully support the growth and development of these economies.
