A GIS APPROACH TO ESTIMATING THE VALUE OF RAIL CAR ACCESSIBILITY FOR GRAIN SHIPMENTS

This study's purpose is to empirically estimate the value of rail car accessibility to producers. Changes in transportation flows for different levels of rail usage in the 20 county grain production region of Eastern Washington are also determined. A transportation optimization model, implemented through a Geographical Information System (GIS) incorporating grain movements originating from 695 township centers and passing through over 400 grain elevators en route to final destinations is descriptively and analytically developed. Impacts on producer's (private) cost of transportation are estimated. Producer's cost is estimated by constraining the volume of grain shipped on rail, thereby generating shadow prices reflecting the marginal value associated with relaxing rail constraints. Description of the data acquisition and modification procedures are first presented, followed by the transportation optimization model description.
