1. The document discusses an integrated transport system model for GCC countries called ITSAM that includes an integrated transport network, information system, and framework for analysis. 2. It presents an international freight transportation equilibrium model called IFSTEM that models multi-modal, multi-commodity freight flows and was applied to a prototype network. 3. The results of applying IFSTEM to the prototype network are presented and include final transportation solutions and costs for different origin-destination pairs as well as comparisons to observed data.
