Abstract:
In many regions throughout the world, freight models are used to aid infrastructure investment and

policy decisions. Since freight is such an integral part of efficient supply chains, more realistic

transportation models can be of greater assistance. Transportation models in general have been moving

away from the traditional four-step model into activity-based and supply chain-based models. Personal

transportation models take into consideration household demographics and why families travel.

Freight research has yet to fully identify the relationships between truck movements and company

characteristics, so most freight models use the methodology of personal transportation models, despite

situational differences. In an effort to classify freight companies into groupings with differentiated

travel movements, a survey of licensed motor carriers was designed and conducted in Oregon. The

survey consisted of 33 questions. Respondents were asked about their vehicle fleets, locations served,

times traveled, types of deliveries, and commodities. An analysis of the data revealed clusters of

company types that can be distinguished by determining characteristics such as their role in a supply

chain, facilities operated, commodity type, and vehicle types. An assessment of how the relationships

found can be integrated into state models is also presented.
