The background questions preceding the stated choice menus in the survey
instrument were designed to quantify the scope and type of operations for each
shipper, experience along the corridors in the study, and the nature of cargo
with respect to its perishability and any relevant delivery time windows.
Respondents are first asked to indicate whether their firm is (or is part of)
a multinational organisation, along with the specific role they play in shipping
freight (that is, manufacturer, wholesaler/distributor, retailer, freight forwarder,
all with or without owning their own trucking operations).
