Modeling the Transition to Advanced Fuels and Vehicles
Principal Objectives of the Project
This project developed the Transitional Advanced Fuels and Vehicles (TAFV) Model, and is now developing HyTrans, a model to study the Hydrogen Transition.
The principal goals of the Transitional Advanced Fuels and Vehicles Model are:
- To account for the effect of AFV incentives/programs on vehicle supply behavior (vehicle diversity and price).
- To account for the effect of early AFV incentives/programs on fuel demand patterns and fuel distributor behavior (fuel availability and retail price).
- To determine the combined effect of these changes on the time path of household alternative vehicle adoption.

Model Features
- Solves yearly, 1996 - 2010
- US focus, urban and non-urban regions
- Tracks the on-road vehicle stock by vehicle and fuel type and vehicle technology
- Tracks sales of new vehicles in each year by vehicle and fuel type
- Accounts for the impacts of fleet mandates on manufacturer, consumer, and fuel retail behavior
- Estimates the costs and benefits of alternative scenarios
- Possibly estimates the energy imports (?) and greenhouse gas emissions
