A TRANSPORTATION-SENSITIVE MODEL OF A REGIONAL ECONOMY

AN INTEGRATED MODEL SYSTEM FOR ANALYZING ALTERNATIVE REGIONAL MULTIMODAL FREIGHT TRANSPORTATION INFRASTRUCTURES IS DEVELOPED. AN ECONOMETRIC MODEL USES TRANSPORTATION PRICE INFORMATION TO DETERMINE THE ORIGIN DESTINATION FLOWS OF COMMODITIES THROUGHOUT A REGION. THESE FLOWS ARE INPUT TO A FREIGHT MODAL SPLIT MODEL, WHICH APPORTIONS THEM AMONG THE VARIOUS MODES ON THE BASES OF RELATIVE TRANSPORT SERVICE VARIABLES. A NETWORK SIMULATION MODEL ASSIGNS THE COMMODITY FLOWS BY MODE TO SPECIFIC ROUTES AND CALCULATES FLOW- DEPENDENT ORIGIN-DESTINATION IMPEDANCE VALUES. EQUILIBRIUM VALUES OF MODEL OUTPUTS ARE ATTAINED BY MEANS OF A MULTI- FEEDBACK ITERATION PROCESS. THE NATURE OF MODEL SYSTEM INTERACTIONS IS EXPLORED BY APPLYING THE MODEL TO A HYPOTHETICAL REGION. /AUTHOR/
