Abstract: A method for generating an optimized regional architecture for efficient national transport is provided. The method integrates vehicle powertrain architectures, operations logistics, and energy pathways to optimize both behind-the-fence and public access energy dispensing solutions supported by local distributed energy resource equipment and centralized fuel sourcing. More specifically, the method provides an optimal regional architecture for electrified national transport modeling. The method assimilates critical data for seasonal operating scenarios to provide a regional specific constrained-optimal infrastructure deployment solution. As discussed herein, the present invention provides local government agencies, industry end users, energy suppliers, and equipment providers with a flexible planning tool to navigate the deployment of electrified freight transportation systems in view of localized constraints.
