What is the role of trade terms in global transportation? Briefly describe and explain the four groups of Incoterms. How are air cargo rates calculated? Calculate the cost of international air transportation for the following shipment: $200$ cartons of fine jewelry weighing a total of $2,500$ pounds. The carton dimensions are $18$ inches by $12$ inches by $12$ inches $($L $\backslash$times W $\backslash$times H$).$ The freight rate is $$10\mathrm{.}25$ per pound. When developing transportation routes for global freight, what considerations should influence the decision maker? We have all experienced highway congestion and $$bumper$-$to$-$bumper$$ traffic, but congestion is a huge issue for supply chains and transport service providers. Why? The U$.$S$.$ Environmental Protection Agency has implemented the Smart Way Transport Program. Discuss the nature and role of the program. DO you think it will be effective? Why or why not?
