An Activity-Based Assessment of the Potential Impacts of Plug-In Hybrid Electric Vehicles on Energy and Emissions Using One-Day Travel Data


With the success of Hybrid Electric Vehicles (HEVs) in the automobile market, Plug-In Hybrid Electric Vehicles (PHEVs) are emerging as the next evolution of this attractive alternative. PHEV market penetration is expected to lead to lower gasoline consumption and less emission. The main objective of this research is to assess PHEVs’ energy profile impacts based on simulation of vehicles used in activity and travel patterns drawn from the 2000-2001 California Statewide Household Travel Survey. Simulations replicating reported continuous one day data are used to generate realistic energy impact assessment of PHEV market penetration.

A secondary objective is to estimate the decreased gasoline consumption and increased electricity demand in California. This will involve testing various scenarios involving battery charging to develop policies and strategies to mitigate the recharging demands placed on the grid during periods of peak consumption.
