Selection of freight transport services is a twofold process, which covers modal choice and carrier choice. Modal choice could be either a specific mode or intermodal transportation. The shipper chooses a particular mode and also chooses between similar services within the chosen route-mode. However, freight transport market is highly complex and contains a wide range of quite different types of services, and shipper can select either a specific carrier or intermediary (Davies and Gunton 1983). Besides the selection of mode, also origins, destinations, shipment sizes and, nodes (e.g., water port, and airport) can be selected by the shipper.
