A MULTI-COMMODITY, MULTI-CLASS GENERALIZED COST USER EQUILIBRIUM ASSIGNMENT MODEL

The paper presents the development of a transportation demand-forecasting mode for assigning multi-commodity, multi-class truck trips between various origin and destination points. The model takes into account the impacts of congestion on truck route choice and is implemented as a Geographic Information System (GIS) within the TransCAD software package and Microsoft Access. It is used to ascertain impacts of proposed capital improvements on the transportation network performance. The objective is to demonstrate how the model can provide the freight transportation planner with an initial assessment of the magnitude of changes in the traffic flow and the user costs. This will enable the planner to better understand the problem at hand so that he/she can identify an issue/area that required further study. As an application, the model is used to analyze freight traffic on New Jersey highways and five transportation policy scenarios.
