THE GEOGRAPHY OF TRANSPORT SYSTEMS
| Transport Sector | Function |
| Maritime shipping companies | Control long distance segments of the global freight distribution linking major markets. Highly capital intensive industry. Decide of their network configuration (ports of call and routing). |
| Global port terminal operators | Control important intermodal infrastructures (terminals) within the world's largest container ports. Have strong linkages with maritime shipping companies. |
| Port authorities | Manage and plan port infrastructures. Tend to lease terminal operations. Important intermediaries for regional distribution (hinterland). |
| Maritime lock and canal operators | Operate strategic passages in global and national distribution (e.g. the Panama Canal, the Suez Canal or the St. Lawrence Seaway). |
| Real estate promoters | Develop logistics zones (build to lease, build to suit), often in coordination with terminals (rail and port). Manage a real estate portfolio of distribution centers (leases). |
| Rail and rail terminal operators | Strategic inland freight carriers transporting a wide array of raw materials and commodities. Responsible for many of the transshipments between rail and road, particularly for containerized freight. |
| Trucking industry | Control vast and diverse assets that include critical segments of freight distribution in all economic sectors. Short and medium haul transport. |
| Third party logistics providers | Important managerial and organizational skills within supply chains. Often act as brokers between transport customers and service providers. Some own and operate transport assets. |
| Air freight transport companies and air freight terminals | Important assets for the rapid distribution of high value added freight. Decide of their network configuration (airports serviced). |
| Freight forwarders | Perform tasks such as packaging, labeling and the consolidation of shipments on behalf of their customers. Operate distribution centers. Define how markets are serviced. Can subcontract to third party providers. |
