The freight community has a unique perspective on how deteriorating pavements, bridges, roadway geometry and congestion affect the movement of freight. As an initial step in the transportation planning process, information should be gathered from the freight community on current conditions and their perceptions of problems. In order to establish the most effective means of gathering these perceptions, the Oregon Department of Transportation sponsored a series of pilot studies to develop a methodology for conducting surveys of shippers and motor carriers. A telephone survey methodology was developed that was capable of yielding a 60 percent response rate. A full-scale random survey of nearly 3,6000 firms throughout Oregon achieved a 61 percent response rate and produced more than 2,200 problem descriptions, locations, and perceptions of the impact being caused by these problems. Survey responses were collected verbatim in a text format and a coding strategy was used to assign each response to a problem category such as infrastructure, congestion, restrictions, other drivers or construction. Further research and electronic mapping of information may be needed to assess the usability of the reported location of problems, especially for areas of problem congestion. This survey methodology can easily be used by other states or regions to solicit their freight community's input. The methodology also could potentially be used to create a national dataset.
