MODELING WASHINGTON STATE TRUCK FREIGHT FLOWS USING GIS-T

William R. Gillis, Waynette Nell, K L Casavant

Abstract

A particular challenge faced by State Departments of Transportation and Metropolitan Planning Organizations is obtaining comprehensive information on freight truck movements. The Washington State Department of Transportation (WSDOT) initiated a statewide freight truck origin and destination study in April of 1993 to meet this challenge. This paper provides an overview of research procedures utilized in conducting the study. Specific focus is given to the role of GIS-T as a tool for organizing, analyzing and presenting data for use by transportation planners, program administrators and policy makers. A case study of southbound trucks on SR 395 from Canada to Spokane, Washington illustrates the practical uses of GIS-T as a means to document and analyze the characteristics of freight truck movements.
