2.2. Multimodal transport cost-model
Banomyong and Beresford (2001) explained that the multi- modal transport cost-model includes both transport (road, rail, inland waterway and sea) and intermodal transfer (ports, rail- freight terminals, inland clearance depots) as cost components. This model has been adapted from Beresford and Dubey in 1990 and improved by Beresford in 1999. Transport costs combine intermodal transfer cost. The highlighted model affects choice of transport modes or combination of modes for given movements. The model could also assist in the logistics trade-offs, such as those between speed and costs, to be thoroughly examined in a range of circumstances. The choices of multimodal transport com- binations are based upon factors other than just transportation costs, which are directly related to transit time, distance and intermodal transfer. For this reason we use a multimodal
