Abstract
This paper presents a methodology to model statewide truck trips using publicly available data
developed by federal and state organizations. This methodology is applied for the statewide
freight planning of North Dakota. In the absence of ample research funding, states, counties
and metropolitan planning organizations can resort to these freely available data. A state level
commodity-by-industry input-output table customized from a freely available national input-output
table is used to disaggregate trips to the traffic analysis zone level. These databases are available
nationally; hence, the methodology discussed in this paper can be transferred to other states with
relative ease.
